CASE STUDY DUNDON PASSIVHAUS PREWETT BIZLEY ARCHITECTS

摘要

Set at the foot of a wooded hill, the Dundon Passivhaus is an extremely energy-efficient house overlooking the Somerset Levels. Built as a self-build project with the owners as the clients, designers and main contractors, the house replaced a dilapidated 1920s bungalow. By digging the lower floor into the hillside, planning permission was gained for a two-storey house with a roof only marginally higher than the bungalow it replaced. The house is intended to sit unobtrusively in the landscape, emerging from the hillside and nestling into its context. The thermal envelope is defined by thick, timber-framed walls clad with green oak boards. On three sides the shallow pitched roof extends beyond the footprint to create sheltered outdoor spaces that catch the sun at different times of day. An outrigger structure of green oak posts supports the roof and frames views through the covered spaces, binding the building into the landscape.
