The project is composed of a collection of components serially developed through previous projects, but these components are loosely assembled rather than forming a single coherent composition—allowing visual dominance to oscillate between the original and new elements. To the exterior, a sculptural composition of timber and white render is formed by the new rear extension to the lower-ground floor, the ground floor terrace, and the reworked closet wing. However this composition is relatively diminutive in relation to the original building, which dominates this elevation.
The decking timber of the ground floor terrace is continuous with the cladding of the extension below, lending it the character of an occupied under-croft, rather than a building form per se. The loft extension is articulated as an incision into the original slate roof form, and the interior spaces are defined by planes and rectangular volumes that sit slightly detached from the original building.
