Sinfonia Smith Square

Sinfonia Smith Square, home of Smith Square Hall, is a distinctive London venue available for concerts, corporate events, weddings, private celebrations and cultural occasions. Set in the heart of Westminster, this Grade I listed Baroque building combines historic architecture with practical facilities for modern event production.

The main hall creates an impressive setting for receptions, dinners, award ceremonies, conferences, graduations, fashion shows, private performances and Christmas parties. Its soaring canopy ceiling, grand columns, brass chandelier, gallery and portico steps provide a memorable backdrop, while the built-in stage, theatre lighting and in-house PA support speeches, presentations, live entertainment and formal ceremonies. The hall can accommodate up to 500 guests for a standing reception, with flexible layouts available for seated dinners, cabaret and theatre-style events.

For more intimate occasions, the vaulted Crypt offers a separate atmospheric space for smaller receptions, meetings, parties, comedy nights, cabaret and live music. It includes a bar and PA system and can host up to 180 guests.

The venue also provides concert hire with excellent acoustics, flexible staging, professional front-of-house support, dressing rooms, internet access, soundproofing, fixed stage lighting and two Steinway grand pianos. Wedding celebrations are supported by an experienced events team, dedicated catering options and dry hire availability for selected receptions. On-site catering ranges from drinks and canapes to bowl food, afternoon tea and three-course dinners, with vegetarian, vegan and dietary-specific menus available. Its central Westminster location makes Smith Square Hall a compelling choice for organisers seeking an elegant, versatile and highly characterful London venue.
