Domes Resorts has mapped out the next chapter for its newly acquired Casa Collective portfolio, with three Greek openings lined up for Summer 2027: two Casa Cook hotels and a Cook's Club, spanning Halkidiki and Santorini.

The most architecturally interesting of the three is Casa Cook Athos, in northern Greece near the gateway to Mount Athos. The property revives a 1959 Modernist landmark originally designed by Periklis Sakellarios, one of Greece's leading architects of the era. Berlin-based studio Vision Alphabet, founded by Casa Collective's Remo Masala, is handling the reimagining, keeping the building's mid-century character intact. It opens with 60 keys and a further 45 rooms to follow, plus two restaurants serving local dishes and wines built around the Greek idea of paréa — the joy of gathering — direct beach access on a sheltered bay, and a spa running yoga, breathwork, meditation and sound rituals.

Also on Halkidiki, Cook's Club Kassandra will be the brand's first property on the Greek mainland. Set among the pine-covered hills of Kriopigi on the western peninsula, the adults-only hotel is styled as a relaxed private summer house, organised around a central pool and pool bar. There's an open-kitchen restaurant called The Boathouse with locally sourced dishes, a spa, an outdoor gym, a yoga platform and landscaped gardens made for lingering. Art is a bigger part of the plan here than in past Cook's Club openings: contemporary works and large murals run through the hotel, and a partnership with Brazilian artist Luciano Cian kicks off a wider programme of commissions, live murals and occasional artist residencies.

The third opening is the smallest and arguably the most tempting for couples. Casa Cook Santorini sits in the village of Firostefani with just six traditional cave-style residences, whitewashed in the island's signature style and looking out over the Caldera. It's pitched as the brand's design ethos at a more personal scale — tailored experiences, privacy and the freedom to explore Santorini on your own schedule.

Domes CEO Dr George P. Spanos framed the trio as a statement of confidence, noting that the hotels are owned outright by the group, while Masala emphasised building reasons for guests to return without flattening each brand's individual identity.

Why it matters: Casa Cook has a loyal following for its low-key, design-forward take on all-inclusive-adjacent holidays, and Cook's Club is its livelier, adults-only sibling. Until now the brands have been almost entirely island-focused, so the Kassandra opening finally gives mainland-bound travellers an option, while the Athos project — a restored Modernist classic on one of Greece's quieter peninsulas — is the kind of property that tends to sell out early once word gets around. Santorini loyalists who find the island's big caldera-view hotels too big now have a six-room alternative. If any of these appeal, it's worth watching for early-booking rates when 2027 inventory opens.
