Cedar House, Perthshire Walker Architecture
A timber-framed house with a translucent internal screen The construction of the singlestorey house is relatively simple, almost barn-like. It comprises a timber frame supporting a series of assymetrical timber trusses at 600mm centres which span 10.5m and are covered with cedar shingles. Apart from the bedrooms and garage, the walls are formed of timberframed, glazed sliding doors which can be screened by blinds of horizontal cedar slats.
The main entrance lobby is a 3m-wide space which rises to reveal the slope of the roof, expressing the full volume of the structure. The soffit is supported by paired trusses which run above the lobby walls. It is lit by a triple-walled polycarbonate rooflight framed in cedar and set in the south-west pitch of the roof, just below the ridge.
The south-east wall of the entrance lobby is clad with sheets of 16mm triple-walled polycarbonate, a material commonly used for conservatory roof glazing. It has a milky, translucent quality through which the bedroom corridor and structure of the timber wall and truss can be discerned.The 1,200mmwide sheets are trimmed at their edges with standard channels and screwed to a 75 x 45mm softwood frame at 600mm intervals; the screws - as used for roof glazing - are covered with white domeheaded caps.
The end of the bedroom corridor, lying behind the wall, is lined with an additional layer of studwork and polycarbonate sheet.
Fluorescent lamps hang in the studwork cavity and are fixed behind the trusses at high level; their light is diffused and refracted by the cellular structure of the polycarbonate.The soffit of the pitched roof, painted a light grey, extends beyond the entrance lobby and above the main living space.
