In Mayfair, close to Green Park and the West End’s galleries, tailors and theatres, Cambridge House, Auberge Collection brings a historic London mansion back into hotel life. The Grade I-listed Georgian house, once the In and Out military club, is being reshaped as a polished city retreat with rooms and suites that are expected to balance Palladian bones, tailored interiors and contemporary comfort. Its mood is formal without feeling frozen: carved stone, grand salons and a sense of old London ceremony, softened by Auberge’s resort-style service. Dining is planned around Major’s Grill, with additional salons for all-day eating and afternoon tea, intimate bars and a fumoir. Wellness is a major part of the project, with a destination spa, swimming pool, bath house, treatment rooms, gyms and studios. The setting is ideal for travellers who want Mayfair’s composure, Hyde Park nearby and central London within easy reach.
