One of Mayfair's grandest old buildings is finally getting a new lease of life. Cambridge House at 94 Piccadilly — better known to generations of Londoners as the former Naval and Military Club, the famous 'In & Out' — will reopen in February 2027 as a 102-key hotel and residences under Auberge Collection, the US luxury brand better known for its resorts.

The project is the centrepiece of a £1 billion regeneration of 1.3 acres of the Piccadilly Estate by the Reuben Brothers, who have restored the Georgian landmark with an eye on keeping its heritage intact. Inside, Parisian designer Jean-Louis Deniot has handled the hotel and guest spaces, while Laura Gonzalez has designed the signature bar, a members club arriving later in 2027, and the wellbeing facilities. The location is a big part of the appeal: quiet Green Park on one side, buzzy Shepherd Market on the other.

The food offering may end up being the headline act. Major's, a new restaurant from Major Food Group — the team behind Carbone and Torrisi — will occupy the restored Georgian ballroom and a jasmine-fringed courtyard. It's billed as the first time MFG has fused its American chophouse style with the traditions of the London grill, with menus built around British produce, seafood towers, caviar service and spit-roasted prime rib carved tableside from bespoke trolleys. The bar will pour ten different martinis, backed by a serious wine cellar.

Wellbeing gets unusual billing too. Spread over three floors and inspired by Britain's Roman bathhouse heritage, the spa will include hydrotherapy, a heated pool, six treatment rooms, wet and heat rooms, and a circular relaxation lounge with a fire pit at its centre — part of Auberge's socially minded 'Joy of Wellbeing' approach rather than a hushed, heads-down spa.

For travellers, this adds a genuinely new anchor to the London luxury hotel scene. Auberge is best known for properties like its Napa and Tulum outposts, so its first flagship-style urban property in the UK capital is a marker of where high-end Mayfair hospitality is heading: experience-led dining, wellness as a social activity, and members' club energy wrapped in a heritage shell. Reservations are already open for stays from February 2027, and event spaces across the restaurants, bars and private rooms will cater to everything from weddings to corporate takeovers.

Worth watching: the members club and bar follow later in 2027, so the property will evolve through its first year. If you want the full experience — Major's, the bathhouse, the Gonzalez-designed bar — a trip in mid-2027 or beyond may be the smarter bet.
