42 Berners Street is the result of a full demolition and redevelopment of two town houses at the prestigious Fitzrovia address. Architect, Buckley Gray Yeoman specified underfloor air conditioning as a means to maximise internal floor to ceiling height, and the final design achieved an extra floor but still within planning constraints. The design brief also stipulated a “flexible building” and to maximise the available lettable space.
The system specified was a CAM-C direct expansion system with full underfloor supply and return air. TU4-EC Fantiles extract conditioned air from the underfloor plenum and introduce it into the workspace. Due to the system’s inherent flexibility, additional Fantiles are easily added according to incoming occupier requirements.
Reaching practical completion in December 2018, the building has transformed the streetscape with its modern façade and bronze windows, and developers are currently finalising lease negotiations with a single client.
