contemporary interior net zero carbon house design
The design intention is to create a contemporary single storey ‘long house’ which is recessive in the landscape, sustainable in its construction, very low in energy consumption, and aiming for zero net emissions of carbon dioxide for all energy use in the house.

The design uses lightweight but highly insulated steel and timber frame construction, clad in cedar weatherboarding allowed to weather to a natural silver grey colour. The roof uses pre-weathered grey standing seam zinc. Windows and external doors are to be high performance timber, painted grey.

The slope of the roof of the main living accommodation follows the slope of the hillside, with the roof of the rear accommodation meeting the main roof at a shallower angle to allow morning sunlight to penetrate the centre of the house.

The entrance to the house is sited on the north east side of the house under the cover of the roof to provide shelter from the prevailing wind. The principal rooms are situated along the contour of the site to sit comfortably in the landscape and enjoy the views across the valley to the west. The ancillary or ‘servant’ spaces are generally at the rear.

It is proposed to achieve a ‘zero carbon’ house by using very high levels of insulation, minimising air infiltration, heating using a ground source heat pump with solar hot water heating panels in the roof and generating electricity using a wind turbine. Surface water run off from the house will be channelled to a pond and used for watering the garden, etc. Foul water will be treated by a sewage treatment plant and reed bed system.
