Smith Square Hall in Westminster, London, is hired for corporate parties, award ceremonies, concerts, weddings and filming. The main hall holds up to 500 guests at a standing reception, 324 in theatre layout and up to 280 at a long-table dinner. A vaulted crypt below takes up to 180 guests. The hall is run by the music charity Sinfonia Smith Square.
Seminars and company events
The hall is a multi-purpose space with a built-in stage and theatre lighting. Theatre layout seats 324, which suits conferences, product launches, shareholder meetings and award ceremonies. A cabaret layout seats 184. The venue lists a PA system and venue uplighting in its sample packages, along with a cloakroom and security. The site also describes the hall as a concert space, with a Klais pipe organ and two Steinway grand pianos, so a company event can include live music on the same stage.
The crypt is the option for smaller functions. It is a vaulted space with a bar and a PA system, and holds up to 180 guests.
Weddings and receptions
Smith Square Hall offers wedding hire in a quiet square in Westminster. The hall's architecture is the main draw: twelve columns, a canopy ceiling, a black and white checkered floor, a gallery, a brass chandelier, gardens and portico steps. Dinner for 220 at round tables or 280 at long tables is stated for the main hall, and the crypt can serve a separate reception or an after-dinner party for up to 180.
Rooms and capacities
The main hall: standing reception 500, theatre 324, dinner at long tables 280, dinner at round tables 220, cabaret 184. The venue's text also quotes up to 440 guests for private performances and award-style events, and up to 300 for a formal seated banquet, which differ from the layout table, so confirm the figure for your format. The crypt: up to 180 guests, with a bar and PA system.
Catering
The on-site caterer is Leafi, which offers several packages. Samples include a three-hour drinks reception with six canapé options, and a drinks reception followed by a three-course dinner. A venue hire brochure is available as a PDF from the website.
History and setting
The building is a Grade I listed 18th-century Baroque church, formerly St John's Smith Square, now known as Smith Square Hall. It has welcomed musicians and audiences since 1969. Its exterior and interior are among the finest examples of English Baroque architecture, according to the venue, and it has been used as a filming location because the square is quiet. Sinfonia Smith Square, the resident orchestra, runs a programme of concerts and a fellowship scheme for young players.
Getting there
The hall is on Smith Square, London SW1P 3HA, in the heart of Westminster. Westminster is the nearest Underground station, and Heathrow and London City are the main airports serving central London.
