The Little Orange Door will replace Balans Soho Society, which has closed after two and a half years, in April.
It will have the same flatshare theme as its sister sites, offering cocktails, bottomless brunches and ‘house parties’ in a space run by ‘flatmates’.
The Little Yellow Door started as an 'immersive' pop-up in Notting Hill in 2014 and has since opened a permanent site in the area.
A sister venue The Little Blue Door launched in Fulham in 2018.
Balans Soho Society began as a Soho sandwich shop in 1987 and is now left with seven London restaurants.
CDG Leisure acted on the Clapham deal.
