/ About
The Biltmore Mayfair occupies a grade II listed Edwardian building on Grosvenor Square, one of London's most recognisable addresses. Opened in 2019 following a comprehensive restoration, the hotel sits within the building's original neoclassical shell while its interiors were entirely remade: 307 rooms, a pillarless grand ballroom, three banqueting suites, and a pair of private dining rooms that open on to corridors papered and panelled in the hotel's distinctly warm palette of brass, herringbone timber, and curated art.
For private events, the hotel offers genuine range. The 484-square-metre Ballroom is the centrepiece: pillarless, divisible into three sections, with a built-in LED wall, configurable coloured ambient lighting, and a private foyer that stands alone as a reception space for up to 250 guests. The Pine Bar operates as an intimate cocktail lounge with deep crimson velvet seating and Art Deco panelling, and is available for exclusive hire. The Manhattan Suite and Waterloo Suite sit at the other end of the scale, suited to dinners and celebrations of 40 to 70 guests, with the Waterloo Suite adding a private outdoor terrace onto Adam's Row.
Two private dining rooms complete the private-hire portfolio. The Chairman's Suite seats 14 around a single long table beneath a crystal chandelier, with herringbone dark wood floors and original artworks on each wall. The Blue Room, by contrast, is entirely self-contained with soundproofed walls hung with ocean-themed pieces, an oval table, and dimmable central lighting. Events catering covers British, Asian, and Middle Eastern menus, with kosher and halal options available. The hotel holds multiple licences and the events team manages load-in, AV, and on-site coordination.
/ Rooms Available
The Ballroom
Exclusive HireA pillarless 484-square-metre grand ballroom with its own dedicated private foyer. The room divides into three independent sections using internal partitions, making it equally suited to full-venue parties of 600 or more contained dinner formats of under 100. A built-in LED wall, configurable coloured ambient lighting, and a full audio system are integrated into the architecture.
Manhattan Suite
PrivateA bright, high-ceilinged suite with views directly onto Grosvenor Square through large sash windows. Divisible into three sections, it suits both long-table dinners and cocktail receptions. A crystal chandelier and warm lighting give the room an evening character quite different from its daytime aspect.
The Pine Bar
Exclusive HireAn intimate, moodily lit cocktail bar. Art Deco panelling runs floor to ceiling, and deep crimson velvet armchairs are arranged around low marble-topped tables. Available for exclusive hire from 4pm, with a programme of fine spirits, cognac, and bespoke cocktails. Capacity for around 60 guests standing.
Waterloo Suite
PrivateAn 80-square-metre suite with a private connecting outdoor terrace overlooking Adam's Row. At this scale it works best as a dinner for 40 or a cocktail reception for 60. The terrace extends usable space in warm weather and gives guests a discreet outdoor option without leaving the venue.
Kendal Suite
PrivateA compact 43-square-metre room suited to smaller gatherings and breakout sessions, with natural light through tall windows and a wall-mounted screen.
The Chairman's Suite
PrivateAn intimate private dining room for up to 14 guests, with herringbone dark wood floors, a crystal chandelier overhead, and a curated collection of paintings on each wall. The long central table and formal room proportions make it one of the hotel's most serious spaces for a small, considered dinner.
The Blue Room
PrivateA fully soundproofed private dining room for up to 10 guests, walled with ocean-themed artwork in brass-framed panels. An oval table sits beneath a contemporary multi-arm chandelier with dimmable lighting. The room's acoustic design makes it unusually quiet for its size.
