This lovely little house showcases a variety of stunning timber claddings, a renewable alternative to plasterboard and cement sheet. Radial cut timber boards imbue this compact home with a softness and warmth that is only possible with natural materials.

Sustainable strategy:

Water Saving: above ground water tank used to irrigate the permaculture garden, low water native garden at front requires little water

Passive Design: warped gable roof provides shading to north & east facing windows, highlight windows allow light to penetrate deep into the living space, there is zero western glazing to protect from the harsh summer sun, airlock between living & bedrooms, operable windows located for cross ventilation

Building materials: Brick thermal mass wall, Sustainable materials are used throughout from the radial cut timber weatherboards to the internal plywood clad walls, plasterboard has no place in this eco design, steel framing minimised

Windows: Timber high performance double glazed windows

Active Heating & Cooling: Woodfire heater is located on thermal mass wall located to capture northern sun and separate the kitchen from the living room, ceiling fans

Lighting: Daylight maximised, LED fittings

Paints, finishes & floor coverings: floating floor over concrete slab, low VOC paint throughout, external blinds shade doors & windows where necessary

Other ESD features: building footprint minimised to preserve garden for growing food, mezzanine nestled into roof spaces reduces overshadowing to neighbours
