Burdett Suite at No.11 Cavendish Square

The Burdett Suite operates as a self-contained event space on the ground floor of No.11 Cavendish Square — its own entrance via Dean’s Mews, its own registration area, two green rooms, and direct access to the Orangery and courtyard garden for catering and breakout. It’s the venue’s dedicated large-format space, recently refurbished with conference-grade technology that sits behind the Georgian townhouse’s period exterior.

Conference and Theatre Setup at No.11 Cavendish Square’s Burdett Suite

The Burdett Theatre anchors the suite with a pillar-free, contemporary interior that seats 282 theatre-style — some sources list 248–280 depending on configuration. Classroom holds 132, cabaret 120, and dinner layouts seat up to 200. A configurable stage with a portable accessibility lift gives flexibility for presentations, panels, and awards formats. The recent lighting upgrade installed LED spotlights with dynamic colour-matching capability, useful for brand activations and award ceremonies where the lighting needs to do more than illuminate. Three projectors and screens, a conference lectern with comfort monitor, a PA system with recording and streaming capability, and HD cameras for hybrid events come as standard. A dedicated AV technician is included in every hire — not an optional extra. The suite’s 500MB WiFi supports live streaming and hybrid participation without the bandwidth anxiety that older venues often create.

Indoor-Outdoor Flow at No.11 Cavendish Square’s Burdett Suite

What distinguishes the Burdett Suite from comparable conference spaces is its connection to the Orangery and courtyard garden. The Orangery — a bright, glass-ceilinged conservatory — serves as the natural catering and networking space for conferences, while the courtyard adds genuine outdoor breakout for summer events. Standing capacity across the whole suite reaches 300–400 when the Orangery and courtyard are included. That combination of serious AV infrastructure and al fresco networking space is unusual at this capacity level in central London.

Evening and Celebration Events at No.11 Cavendish Square

After-hours, the suite transforms for gala dinners seating 200, dinner-and-dance formats for 150, and standing receptions. The LED lighting system shifts from conference-neutral to atmospheric, the courtyard garden adds evening dimension with bespoke wall lighting, and the self-contained floor plan means evening events don’t share circulation with the rest of the building. Searcys handles all catering with seasonal British menus across formats from working lunches to black-tie service. The private Dean’s Mews entrance means guests, production teams, and catering deliveries all arrive without crossing the main building — the cargo lift handles heavy equipment. AIM Gold accreditation signals professional event delivery standards, and the 20% health and social care discount applies through the venue’s King’s Fund connection. Oxford Circus and Bond Street stations are both within a five-minute walk.
