No.11 Cavendish Square

Situated in the heart of London’s West End, No.11 Cavendish Square is a Grade II listed Georgian townhouse with stunning original features complemented by an exquisite contemporary design. The venue houses 20 flexible event spaces spread across four floors, including several large lecture theatres, breakout rooms, board rooms, and a light and airy Orangery and Courtyard garden ideal for alfresco entertaining. Conference and meeting facilities include the Burdett Theatre (seating capacity 282), the Maynard Theatre (capacity 165) and the Marlborough Theatre (capacity 86), with 4 adjacent break-out rooms, all equipped with the latest AV technology. The Burdett Suite, adjacent to the Orangery, is ideal for large conferences, grand-scale celebrations and flamboyant entertainment as it can be re-configured in many ways, providing you with the freedom to design your event or meeting the way you want. The Orangery offers contemporary style bathed in natural daylight from the glass ceiling and a delicate citrus aroma from the orange trees. The spacious, open-plan room provides a stunning setting for receptions, celebrations and exhibitions. The courtyard garden features a delightful lush green ‘living wall’ installation and water feature with high wooden stools and tables for seating. It is a delightful space in which guests can relax. Few venues in central London can boast such a wonderful outdoor area, which is perfect for an informal drinks reception.
