Sanctum Soho Hotel

Project Information

Sanctum Soho Hotel
Warwick Street, London W1

The site consisted of two finely crafted period buildings, one of which is Grade II Listed.  It is located in the heart of Soho and much of our research was based on the architectural context of the area.


We converted the buildings from office space into a boutique hotel.  The period façades were retained, whilst a new steel framed structure was added behind them to allow common floor levels across both buildings.  A new roof storey was also constructed.  We sought innovative solutions to make the building more efficient, investigating a number of energy solutions including ground source heat pump technology.


The hotel is designed to the highest specification. It hosts public functions on the ground and basement floors with a restaurant, bar and preview cinema.  The thirty private rooms are situated above and a spa was constructed in the roof storey along with other outdoor facilities.
