Challoner House


Significant restoration, refurbishment and extension of Nos. 19-21 Challoner House, a four storey locally listed office building located on Clerkenwell Close. Externally the works include the replacement of the existing mansard with a green roof; new roof extensions above; as well as the reinstatement of numerous architectural features to the historic front elevation. The contemporary extensions to the rear of the site are designed to be harmonious with the existing buildings and the wider context, using a palette of steel and glass that reflects the light industrial heritage of the building as a zip factory.
