An impressive two-storey timber extension to a historic office building

As part of the works to renovate and re-purpose this historic office building in Farringdon, London, we used both our specialist timber expertise and our extensive experience working with existing buildings to design a two-storey timber rooftop extension.

The extension comprises an additional floor, and an additional mezzanine floor. Two internal glulam column lines support Baubuche beams at mezzanine and roof level, which in turn support cross-laminated timber (CLT) panels. CLT panels form perimeter walls, with the long elevations pitched to form a mansard with large windows.

The result is an impressive, sustainable and flexible office space.
