Our Private Party Spaces

Discover our three event spaces which are best suited to hosting private parties in central London.

Located on the first floor, the Argyll Room is one of the most unique spaces in London. This elegant room boasts large bow windows and a west-facing garden terrace, making it perfect for a memorable event. In the summer, the outdoor terrace can be used for sunny barbecues, or in the winter it can be transformed with a heated marquee so that you can still enjoy this beautiful space. The Argyll Room and Terrace can host up to 200 guests for a reception or 100 guests for a private dining experience. Plus, this room can be hired with or without furniture and adapted to any style to suit your event requirements.

Our largest event space, the Bill Boeing Lecture Theatre, works as a blank canvas space which can be transformed for parties and dinners of up to 200 guests. This fully air-conditioned space is equipped with the latest audio-visual aids and fully qualified technicians are available to assist with any equipment you may need. Included in room hire is AV equipment such as coloured ceiling LED lights, wall-mounted screens, in-house PA sound system and microphones.  The Marshall of Cambridge Room & Foyer is perfect for smaller private events of up to 120 guests. This elegant room is located on the ground floor and boasts plenty of natural light. Adjoining the Bill Boeing Room, these spaces can be combined for larger private events, or used for catering breaks.
