Orangery & Courtyard at No.11 Cavendish Square

A glass-ceilinged conservatory and a private walled garden in the heart of Mayfair — the Orangery & Courtyard at No.11 Cavendish Square gives evening receptions and celebrations something that almost no W1 venue can offer: genuine indoor-outdoor flow without leaving the building. The Orangery is bathed in natural light from its vaulted glass ceiling, with a gentle citrus aroma drifting from the orange trees that line the space. Open-plan and airy, it runs from the main venue through to large sliding glass doors that open directly onto the courtyard. That transition — conservatory to walled garden in three steps — is what makes the space work for events. Guests move naturally between inside and out without bottlenecks, queues, or the awkward funnel that most venues create when they bolt on an outdoor area.

No.11 Cavendish Square’s Courtyard Garden

The courtyard itself is enclosed by a living wall that changes character with the seasons: vivid colour through spring and summer, dark evergreen foliage through winter. A rustic central water feature provides ambient sound, and bespoke LED lighting threads through the planting for evening atmosphere. Upper and lower decks create natural zones for different groups without formal barriers. It holds 120 standing on its own, but works best as the breathing space alongside the Orangery’s larger capacity.

Capacity and Event Formats at No.11 Cavendish Square’s Orangery

Combined standing capacity reaches 280–300 guests. Wedding ceremonies seat up to 160, wedding breakfasts up to 144, with a minimum of 80 guests for the No.11 Package. The space sits on the ground floor with full accessibility from the main entrance. A removable stage accommodates bands, DJs, or speeches, while a PA system covers both indoor and outdoor areas. Dynamic lighting can match brand colours for corporate launches.

Weddings and Celebrations at No.11 Cavendish Square

Wedding bookings get particular mileage from the courtyard — outdoor photography in a private setting without leaving the venue, drinks receptions under the living wall before guests move inside for dinner, and a genuine sense of occasion that a single-room hire rarely achieves. The adjacent Garden Room, with its 18th-century wallpaper and views across both Cavendish Square and the courtyard, extends the options further. Searcys provides all catering in-house with seasonal British menus. Standard evening hire runs 6pm to midnight, with additional hours available. The venue includes a PA system with Bluetooth, roving microphones, digital branding screens, multicolour LED lighting, and 500MB WiFi in the room hire — no hidden AV costs. A dedicated Event Manager coordinates everything from planning through to the night itself. For summer parties, product launches, and wedding receptions that need a West End address with genuine outdoor space, the Orangery & Courtyard at No.11 Cavendish Square delivers a combination that Mayfair almost never provides. Oxford Circus is 400 yards away. The courtyard makes it feel much further.
