Domes Resorts, owner of all three hotels

Founded in 2008, Domes Resorts runs five-star hotels in Greece, Portugal and Spain, eight of them under Marriott brands and three under Hilton brands. In April 2026, the group became the majority shareholder of Casa Collective, the company behind three brands: Casa Cook, which the brand presents as a collection of luxury boutique hotels, Cook’s Club, a more accessible lifestyle brand, and XIA.

In the group’s press release, George P. Spanos, CEO of Domes Resorts and Chairman of Casa Collective, describes the acquisition of Casa Collective as an important step in the group’s growth strategy, one that will allow it to expand its lifestyle ecosystem while building on the distinct identities of Casa Cook and Cook’s Club. In his view, these three openings, in hotels the group owns, show how strongly it believes in the soul and character of these brands.

A 1959 hotel facing Mount Athos

Casa Cook Athos will stand near Ouranoupoli, 300 m from the village centre and 90 minutes from Thessaloniki airport. It will take over the Xenia Ouranoupolis, designed in 1959 by architect Periklis Sakellarios as part of the Xenia hotel programme. The building is an example of post-war Greek modernist architecture, with details inspired by the monasteries of nearby Mount Athos.

60 keys, two restaurants and the beach

Berlin studio Vision Alphabet is redesigning the hotel, which will open with 60 keys: rooms, suites and a villa. A second phase will add 45 rooms. The hotel will have two restaurants, direct beach access and a spa focused on yoga, breathwork, meditation and sound rituals. It will welcome guests aged 12 and over.

The Casa Cook website announces an opening in May 2027, with bookings “opening soon”; the group’s press release, for its part, mentions summer 2027. Rates have not yet been published.

What will Cook’s Club Kassandra offer?

Also in Chalkidiki, Cook’s Club Kassandra will open in summer 2027 in Kriopigi, on the Kassandra peninsula. It will be the first Cook’s Club on the Greek mainland, adults-only and conceived as a summer house around a main pool with its own bar.

It will feature The Boathouse restaurant, a spa, an open-air gym, a yoga platform and gardens. Artworks and murals will decorate the property, including a collaboration with Brazilian artist Luciano Cian. No official images of this hotel have been released yet.

Santorini: homes carved into the rock

In Firostefani, above the caldera, Casa Cook Santorini will occupy cave houses carved into the rock, former wine cellars and old shelters. Adults-only, it will be, according to the brand, the most intimate of the Casa Cook hotels.

The two official sources do not yet agree: the press release announces six residences and an opening in early Q2 2027, while the Casa Cook website mentions seven rooms and a first season in June 2027. In the meantime, see the best hotels in Santorini with caldera views.

After Crete and Rhodes, eyes on 2027

These projects follow a busy 2026 for the group. Domes Resorts opened Aulūs Chania, with 200 adults-only rooms and suites, in Stavros, Crete, and Aulūs Lindos Rhodes, a family hotel near Lardos. It also added Chora, a 16-suite adults-only extension, to Domes of Elounda in Crete; Elounda is also where the Rosewood Blue Palace resort will reopen in 2027.

Greece will see other adults-only addresses open the same year, such as the Ella Elyra, due in June 2027 in Corfu.
