Construction Type: Standard timber frame
Year of Construction: 2020
Brief
Bluegum: This conventional suburban style plan with an integral garage, living areas facing the street and a covered veranda across the rear is enhanced by the use of clerestory glazing.
Description
This high-level glazing brings sunlight into the living areas (which face away from the sun) and free solar energy which enables the house to achieve Passivhaus Plus. Walls are standard 90mm timber studs with rendered external insulation cladding. The roof is timber trusses with glasswool insulation. The floor is insulated above the slab to eliminate thermal bridges from the structural piers. Window frames are Upvc. More information is available here.
Special Features
Large clerestory glazing was used to compensate for poor solar access to windows.
The Brief
A tow living room, 3 bedroom , two bathroom house with large veranda and integral garage on a low budget.
