The 300m2 Passivhaus will occupy an abandoned Victorian concrete water tank
The concrete water tank once served the village of Dunlop, which lies on the hill below the proposed site.
Having sat empty for a number of years, the Victorian water tank is to be repurposed as the site for the dwelling.
Sitting within the hillside, the house is insulated by the earth to the north, with all the living spaces facing south, looking over a newly created courtyard garden.
The house will be a block and timber kit hybrid construction, featuring timber triple glazed windows, natural slate and pre-patinated copper cladding and a sedum roof. The construction is designed to be thermal bridge free.
Renewable energy systems will also be incorporated, including photo voltaic panels and a vertical axis wind turbine manufactured by UK based company, Quiet Revolution.
The project is due to be completed in summer 2013.
