About The Green House at No. 11 Cavendish Square

The ground-floor Green House is one of our favourite spaces at No.11 Cavendish Square. This 140 person capacity room in the townhouse’s contemporary building has amazing features to ensure smooth running of your event. There is a stunning central wood panelled champagne bar for serving nibbles and drinks, two 65in LED monitors with a sound bar, and a cool Sonos wireless music system. The room is also bathed in natural light thanks to large high windows which offer a beautiful view all day through to night. Centrally located within the buzz of Oxford Circus in the heart of the West End, the Green House has excellent public transport links to mainline stations.

The venue space remains true to the origins of the Grade II listed townhouse while still being modern and excitingly innovative in its design. The truly versatile room can be used for a variety of functions from hosting the annual office Christmas party to corporate dinners or an elaborate awards ceremony. No matter the season, summer or winter, the venue sparkles with natural light or can be lit up from within to create a whole new atmosphere for the DJ to take the night away. You can trust in the team at No.11 to help you plan the ultimate event, stress-free.

While receptions are an option and great use of the space, the room shines best for celebrations or dinners. There are different possible layouts for each type of event. Seating capacities for dinner or lounging are for 80 spaces. Catering comes from Dish, the in-house restaurant with delicious themed menus for indulgent lunches and bespoke dinners for special occasions. The catering minimum spend is £3500 on weekends. The room is available Monday to Friday from 6pm and can be hired for 8 hours with additional charges for every subsequent hour.

Testimonials For The Green House At No. 11 Cavendish Square

'Thank you once again for everything'FEBRUARY, 2020

I just wanted to say a huge thank you to both of you for going above and beyond with our event. All the bits that cropped up – like getting a sign on the green room door so our team didn’t barge in when the teleconference was happening were wonderful – it’s those small details that really stand out (and of course, everything else went without a hitch). I can’t tell you what a difference it meant. The arrangements were amazing, and you clearly work as a very tight-knit and friendly team. James – a particular thank you to you for insisting on that technical run through. It made all the difference – we were able to allocate resources accordingly and could brief a team member to collect everyone up and bring them over. We overran only because our final speaker was asked so many questions – for the rest of the day everything was pulled back to time. Thank you once again for everything.

'We certainly want to book for next year'NOVEMBER, 2019

I'd be grateful if you could get back to me on possible dates for 2020; From the experience of yesterday we certainly want to book for next year. It was all quite perfect. The venue is great, fantastic AV, wonderful food - which lots of delegates mentioned. The staff were all both efficient and very friendly, which makes a difference. Even the chairs were comfortable - at a Conference you spend all day sitting and at some venues I've been to they've been instruments of torture! Thank you, very well done - consider us regular customers.
