The Octagon sits proudly on the first floor of House 21, where an 1820s Neo-Classical ceiling presides over every gathering. We've watched countless celebrations unfold beneath its ornate plasterwork, from intimate wedding breakfasts to focused board meetings around our polished tables. Natural light pours through tall windows overlooking our courtyard garden, while French doors open onto a private balcony, perfect when your guests need a breath of fresh air between courses. The room's warm tones come alive in the evening when we light the candles and the original fireplace casts its glow across the space. We can arrange The Octagon in various configurations to suit your needs. For banquets, we seat up to 40 guests at round tables with our elegant clear chairs. Theatre-style presentations work beautifully here for 48 attendees, while cocktail receptions flow naturally with space for 50 guests to mingle. The illuminated alcoves displaying fine glassware add an extra layer of sophistication that particularly impresses at evening events. Our events team regularly transforms this space for different occasions. Morning board meetings for 18 executives benefit from the room's natural acoustics and privacy. Afternoon presentations utilise our U-shaped setup for 36 participants, encouraging discussion and interaction. Evening wedding dinners become magical affairs with candlelight reflecting off the ceiling's intricate details. The lift access ensures all your guests can join you comfortably, regardless of mobility requirements. Being in the heart of London means excellent transport connections, with several tube stations within walking distance. Whether you're planning a milestone celebration, corporate presentation, or networking event, The Octagon offers both the historical character and practical amenities your occasion demands. Our kitchen team works closely with you to create menus that complement the space's elegance, while our events coordinators ensure every detail runs smoothly.
