1 Hotel Mayfair can host meetings, workshops, receptions and private dinners for 10 to 70 guests in a set of event rooms with windows over Mayfair. The hotel stands at 3 Berkeley Street in London, steps from Green Park, and was built from two existing buildings.
Seminars and company events
The event floor offers six rooms that can be used alone or in pairs. Wild Oat is a boardroom for 10. Foxtail takes 25 for a reception or 20 theatre style. Sweet Reed, Field Wood and Clover each take 30 for a reception, with 20 at a banquet table and 15 in classroom layout. Joined rooms give more space: Foxtail Sweet Reed takes 70 in theatre, 60 for a reception and 40 for a banquet, and Field Wood Clover is advertised for up to 60. Field Wood has sound systems and projector screens. The hotel offers a certified sustainable gatherings program for organisers who want to report on their event.
Weddings and receptions
The hotel lists private dining and social events among its offers, with rooms for receptions and celebrations. It does not publish a dedicated wedding program on the pages we reviewed, so couples should ask the events team what is possible for a ceremony or wedding meal.

History and setting
The hotel was built and refurbished from two existing buildings and designed to reduce CO2 emissions. It has living green walls fed by rainwater from the roof and 1,300 plants, shrubs and trees. Rooms use filtered water taps instead of single-use bottles. Mayfair is surrounded by Royal Parks, galleries and theatres.
Getting there
The hotel is steps from Green Park, in central London. Guests can walk through Green Park, St James's Park or Hyde Park, and the hotel lends a fully electric Audi for city trips.
