The Maybourne Saint-Germain hotel to open in 2027 in the former headquarters of the Ministry of Armed Forces

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

Converting a 17th-century military headquarters into a hotel means dealing with a structure that was never designed for hospitality: load-bearing walls everywhere, administrative layouts, and heritage protection. It is the kind of project where opening dates often slip. The second half of 2027 is currently the target; we shall revisit this when the hoardings come down.

Practical Information on The Maybourne Saint-Germain

• Address · 231 Boulevard Saint-Germain, Paris 7th
• Announced opening · second half of 2027
• Capacity · 101 keys, comprising 51 rooms and 50 suites, plus 23 branded residences
• Dining · six venues, including a Japanese restaurant, a pastry shop, and a tea salon

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

• Owner · Constellation Hotels, backed by the Qatar Investment Authority

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there. The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

A Palace, a Nursery, and 254 Housing Units

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

Converting a 17th-century military headquarters into a hotel means dealing with a structure that was never designed for hospitality: load-bearing walls everywhere, administrative layouts, and heritage protection. It is the kind of project where opening dates often slip. The second half of 2027 is currently the target; we shall revisit this when the hoardings come down.

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there. The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

A Palace, a Nursery, and 254 Housing Units

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

Converting a 17th-century military headquarters into a hotel means dealing with a structure that was never designed for hospitality: load-bearing walls everywhere, administrative layouts, and heritage protection. It is the kind of project where opening dates often slip. The second half of 2027 is currently the target; we shall revisit this when the hoardings come down.

Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there. The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

A Palace, a Nursery, and 254 Housing Units

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

Converting a 17th-century military headquarters into a hotel means dealing with a structure that was never designed for hospitality: load-bearing walls everywhere, administrative layouts, and heritage protection. It is the kind of project where opening dates often slip. The second half of 2027 is currently the target; we shall revisit this when the hoardings come down.

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

Converting a 17th-century military headquarters into a hotel means dealing with a structure that was never designed for hospitality: load-bearing walls everywhere, administrative layouts, and heritage protection. It is the kind of project where opening dates often slip. The second half of 2027 is currently the target; we shall revisit this when the hoardings come down.

Practical Information on The Maybourne Saint-Germain

• Address · 231 Boulevard Saint-Germain, Paris 7th
• Announced opening · second half of 2027
• Capacity · 101 keys, comprising 51 rooms and 50 suites, plus 23 branded residences
• Dining · six venues, including a Japanese restaurant, a pastry shop, and a tea salon
• Wellness · Surrenne spa, 30-metre rooftop swimming pool
• Owner · Constellation Hotels, backed by the Qatar Investment Authority

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there. The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

For two centuries, wars were planned here. 231 Boulevard Saint-Germain, the headquarters of the Ministry of Armed Forces since Napoleon I, will open in 2027 as The Maybourne Saint-Germain. The French State sold the eastern section of the Îlot Saint-Germain in 2019 for €300 million to a Qatari fund. Construction is currently underway behind the hoardings on the boulevard.

What the State Sold, and to Whom

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

A Palace, a Nursery, and 254 Housing Units

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

Converting a 17th-century military headquarters into a hotel means dealing with a structure that was never designed for hospitality: load-bearing walls everywhere, administrative layouts, and heritage protection. It is the kind of project where opening dates often slip. The second half of 2027 is currently the target; we shall revisit this when the hoardings come down.

Practical Information on The Maybourne Saint-Germain

• Address · 231 Boulevard Saint-Germain, Paris 7th
• Announced opening · second half of 2027
• Capacity · 101 keys, comprising 51 rooms and 50 suites, plus 23 branded residences
• Dining · six venues, including a Japanese restaurant, a pastry shop, and a tea salon
• Wellness · Surrenne spa, 30-metre rooftop swimming pool
• Owner · Constellation Hotels, backed by the Qatar Investment Authority

For two centuries, wars were planned here. 231 Boulevard Saint-Germain, the headquarters of the Ministry of Armed Forces since Napoleon I, will open in 2027 as The Maybourne Saint-Germain. The French State sold the eastern section of the Îlot Saint-Germain in 2019 for €300 million to a Qatari fund. Construction is currently underway behind the hoardings on the boulevard.

What the State Sold, and to Whom

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there. The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université.

Practical Information on The Maybourne Saint-Germain

• Address · 231 Boulevard Saint-Germain, Paris 7th
• Announced opening · second half of 2027
• Capacity · 101 keys, comprising 51 rooms and 50 suites, plus 23 branded residences
• Dining · six venues, including a Japanese restaurant, a pastry shop, and a tea salon
• Wellness · Surrenne spa, 30-metre rooftop swimming pool
• Owner · Constellation Hotels, backed by the Qatar Investment Authority

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there. The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

A Palace, a Nursery, and 254 Housing Units

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

For two centuries, wars were planned here. 231 Boulevard Saint-Germain, the headquarters of the Ministry of Armed Forces since Napoleon I, will open in 2027 as The Maybourne Saint-Germain. The French State sold the eastern section of the Îlot Saint-Germain in 2019 for €300 million to a Qatari fund. Construction is currently underway behind the hoardings on the boulevard.

The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

Converting a 17th-century military headquarters into a hotel means dealing with a structure that was never designed for hospitality: load-bearing walls everywhere, administrative layouts, and heritage protection. It is the kind of project where opening dates often slip. The second half of 2027 is currently the target; we shall revisit this when the hoardings come down.

Practical Information on The Maybourne Saint-Germain

• Address · 231 Boulevard Saint-Germain, Paris 7th
• Announced opening · second half of 2027
• Capacity · 101 keys, comprising 51 rooms and 50 suites, plus 23 branded residences
• Dining · six venues, including a Japanese restaurant, a pastry shop, and a tea salon
• Wellness · Surrenne spa, 30-metre rooftop swimming pool
• Owner · Constellation Hotels, backed by the Qatar Investment Authority

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there. The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

A Palace, a Nursery, and 254 Housing Units

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

A Palace, a Nursery, and 254 Housing Units

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

Converting a 17th-century military headquarters into a hotel means dealing with a structure that was never designed for hospitality: load-bearing walls everywhere, administrative layouts, and heritage protection. It is the kind of project where opening dates often slip. The second half of 2027 is currently the target; we shall revisit this when the hoardings come down.

• Wellness · Surrenne spa, 30-metre rooftop swimming pool
• Owner · Constellation Hotels, backed by the Qatar Investment Authority

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated.

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there.

For two centuries, wars were planned here. 231 Boulevard Saint-Germain, the headquarters of the Ministry of Armed Forces since Napoleon I, will open in 2027 as The Maybourne Saint-Germain. The French State sold the eastern section of the Îlot Saint-Germain in 2019 for €300 million to a Qatari fund. Construction is currently underway behind the hoardings on the boulevard.

What the State Sold, and to Whom

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned.

Practical Information on The Maybourne Saint-Germain

• Address · 231 Boulevard Saint-Germain, Paris 7th
• Announced opening · second half of 2027
• Capacity · 101 keys, comprising 51 rooms and 50 suites, plus 23 branded residences
• Dining · six venues, including a Japanese restaurant, a pastry shop, and a tea salon
• Wellness · Surrenne spa, 30-metre rooftop swimming pool
• Owner · Constellation Hotels, backed by the Qatar Investment Authority

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.

The buyer is no stranger to Paris: Constellation already owns the InterContinental, the Hôtel du Louvre, and a Hyatt property there. The fund has owned the Maybourne Group since 2015 and has stated its ambition to triple its portfolio by 2035, aiming for fifteen to seventeen addresses in luxury capitals.

One Hundred and One Keys and Twenty-Three Residences

The details of the project have now been revealed. The hotel will feature 101 keys: 51 rooms and 50 suites, a proportion of suites that immediately positions the establishment at the ultra-luxury end of the market, where the Parisian average hovers around one suite for every five rooms.

In addition, there will be 23 branded residences, split between two interior designers and two streets: seven designed by Pierre-Yves Rochon on Rue Saint-Dominique, and sixteen by Laura Gonzalez on Rue de l’Université. Six dining venues will bring life to the complex, including a Japanese restaurant, a pastry shop, and a tea salon. The spa will be operated under Surrenne, the well-being and longevity brand launched by the group. Three pools are planned, including a thirty-metre rooftop pool reserved for hotel guests and a twenty-five-metre pool for residents.

What the July Agreement Clarified

This is where the story gets interesting, and where the original announcements are now outdated. On 9 July 2026, Regis Maybourne and Constellation Hotels ended their joint venture: Regis Maybourne became the sole owner of Maybourne, the operating company, without the ownership of the hotels changing hands. We reported on this here. Claridge’s, The Maybourne Riviera, and The Maybourne Beverly Hills remain owned by Regis Maybourne. Constellation owns The Connaught, The Berkeley, The Emory, and the Paris and Marrakech projects.

In other words: the hotel on Boulevard Saint-Germain will open under the Maybourne brand, but it belongs to the Qatari side, not the British parent company. The distinction is not trivial for those who follow the ownership of Parisian palaces.

Indeed, this is evident in the quotes still circulating about the project, attributed to Gianluca Muzzi as co-CEO of Maybourne. He no longer holds this position: he stepped down at the time of the agreement to take the helm of Constellation. The statements remain valid, but the title does not.

A Palace, a Nursery, and 254 Housing Units

The rest of the block is designated for a different purpose. According to the town hall of the 7th arrondissement, the overall development includes 254 housing units, a nursery, and a gymnasium on the other sections of the former military site.

This cohabitation is worth noting: within the same block in the 7th arrondissement, an address where a single night will likely cost thousands of euros and social housing units will share the same postal address. This is the exact opposite of the usual model, where palace hotels displace housing.

Our View

Paris has a dozen properties with the prestigious ‘Palace’ distinction, and the waiting list is growing. The arrival of a British brand of this calibre on the Left Bank, where the ultra-luxury offering remains scarcer than on the Right Bank, shifts the centre of gravity slightly. Yet the real talking point is not the number of keys, but the building itself.

For two centuries, wars were planned here. 231 Boulevard Saint-Germain, the headquarters of the Ministry of Armed Forces since Napoleon I, will open in 2027 as The Maybourne Saint-Germain. The French State sold the eastern section of the Îlot Saint-Germain in 2019 for €300 million to a Qatari fund. Construction is currently underway behind the hoardings on the boulevard.

What the State Sold, and to Whom

The general staff vacated the premises in 2016 to relocate to Balard, in the 15th arrondissement. Once vacated, the Îlot Saint-Germain was partitioned. Its eastern section was sold in 2019 for €300 million, following a competitive tender process, to Constellation Hotels, a vehicle owned by Qatar Holding and controlled by the sovereign wealth fund Qatar Investment Authority.
