The project, for a major addition to a 1912 Arts and Crafts style house, is situated on the banks of the Thames in South Oxfordshire, within a conservation area, designated as being of Grand Landscape Value.

The existing house is situated on the edge of the floodplain with grounds leading down to the banks. It is one of a number of scattered buildings, of varying scales and types, that are sited between the denser ribbon of the village of Long Wittenham and the Thames. The project refers to the existing hierarchy of these buildings, with the new addition being understood as a secondary volume to the house. It reads externally as a simple timber clad enclosure, in the manner of adjacent barns, which acts as a foil to the complex form of the existing brick building. The two volumes are unified through a new brick and lime mortar garden wall, which replaces the existing.
