The Old Billiard Room at 8 Northumberland Avenue

The Old Billiard Room at 8 Northumberland Avenue is the venue’s blank canvas — a versatile space within a Grade II-listed Victorian building, steps from Trafalgar Square. Where the adjacent Ballroom trades on ornate grandeur, the Old Billiard Room takes a deliberately different approach: white walls, mirror details, and subtle architectural features that create a classic-yet-contemporary feel. It’s a space designed to be personalised rather than admired as-is, which makes it genuinely flexible across event types.

The Old Billiard Room at 8 Northumberland: Space and Layout

The room holds 500 standing, 300–350 theatre, up to 300 dining, or 200 cabaret — substantial capacity within a space that retains Victorian proportions without the decorative density of The Ballroom. The adjoining Annex extends the footprint, giving two interconnected spaces that work together for larger events or separately when a breakout or secondary zone is needed. The Annex handles up to 140 standing in its own right, with columns and ornate detailing providing architectural character within its clean, adaptable layout. White walls make the Old Billiard Room effective for projection, branding, and bespoke lighting design — clients can transform the space to match their event identity without fighting existing decoration. The room can also operate with its own entrance, useful for events where arrival experience and guest flow need careful management.

Production and Technology at 8 Northumberland Avenue

Cutting-edge event technology and an intelligent lighting system integrate discreetly within the Victorian architecture — state-of-the-art AV that handles conferences, product launches, and presentations without visual compromise. The Old Billiard Room’s production setup is part of 8 Northumberland Avenue’s all-inclusive package: venue hire comes with integrated catering from AlchemyLive (headed by Executive Chef Nate Brewster), production and AV from Opal Fusion, event security, a manned cloakroom, furniture, professional staffing, and a dedicated event manager. That end-to-end model eliminates the need to coordinate multiple suppliers — one team manages everything from first call to final guest exit.

Events in the Old Billiard Room

The blank canvas positioning suits corporate conferences and presentations (300–350 theatre with full AV), awards dinners and gala events (up to 300 seated), product launches and exhibitions (20 stands at 8×6 feet with 200 standing and white walls for branding), and standing receptions at scale. Christmas parties benefit from a specific advantage: DJs are permitted until 2am in the Old Billiard Room, compared to midnight in The Ballroom — making this the preferred late-night celebration space within the venue. For multi-stage events, the Old Billiard Room works in tandem with The Ballroom. The two equally-sized spaces enable uninterrupted guest transitions between different environments — a conference programme in the Old Billiard Room flowing into a gala dinner in The Ballroom, or an awards ceremony using one space for drinks and the other for the main event. Combined capacity reaches 1,000 guests.

8 Northumberland Avenue: Location and Access

The building sits a one-minute walk from Trafalgar Square — London’s geographical centre — with Charing Cross station 0.1 miles away and Embankment within easy reach.

The four supporting meeting rooms (Victoria Room seats 70 theatre; G3 and G4 seat 10 boardroom each), The Salon, and The Parlour (up to 12) provide registration, breakout, and organiser hub options alongside the main spaces.
