The extension of the South London Gallery comprises three interventions dispersed around an expanded site that together more than double the area of the original gallery. A café, exhibition spaces and a flat for an artist-in-residence have been created in the neighbouring derelict house. Behind the house, a three-storey extension has been built to create a double-height room leading to the new Fox Garden and Clore Education Studio. The new education building occupies the footprint of the original lecture theatre that was destroyed after World War II. Two surviving brick walls provided the natural start for the building which links the Fox Garden on one side and the gallery’s garden on the other. Continuing the architectural tradition established by the original buildings, the Clore Studio is a generous single volume topped by a central lantern and also develops themes from the house, with an exposed roof structure to create calmness and warmth.
