Plinth House

The house was in poor condition, the ground floor stepped across numerous levels to accommodate the topography of the site and the ceiling level diminishing to 2m at its lowest point. Combined with the cellular nature of the rooms this resulted in a dark internal environment with little engagement with the dual-aspect garden.

By excavating the garden and partially submerging the rear extension, the ground floor was unified across one level. The perimeter of the extension was wrapped in a brickwork plinth; a sculptural, architectural feature that elevates the functional requirement of a retaining wall through the use of finely detailed pale buff brickwork and solid oak to create built-in seating and garden steps.

The materiality of the plinth, combined with the polished concrete floor, exposed rafters and quality of natural light, give the space its calm, distinctive appearance.

Externally the solid plinth grounds the building, reflecting the datum of the garden level, while a Siberian larch and glazed volume gives the building a lightweight, pavilion-like appearance above ground. The significant level change between the interior and exterior is mediated by pushing the plinth out to create two sunken terraces, allowing the building to engage with the garden in multiple directions.

Standing-seam zinc clads the loft extension, its vertical rhythm echoing the larch cladding, while adding a point of contrast within the composition of forms and materiality which serve to breakdown the overall scale of the house.
