RIBA Head Office

Theis + Khan, the appointed architect, design approach at 76 Portland Place was to create a sustainable and flexible working environment within the confines of the existing 1950s building, the fluidity of this new working environment is in direct contrast to the formality of the current headquarters building. The brief stated that the new offices should be ‘exemplary in environmental sustainability given the constraints of the building’. The open-plan ground floor space flows vertically up the tower to the sixth floor where the openable rooflights create a naturally cooling stack effect. All windows are openable to allow for natural ventilation with supplementary heating and cooling as required.

Theis & Khan appointed Ridlands to partner with them on the project in the knowledge that we could deliver their desired brief and aesthetic within the confines of the budget and building.
