Winner ANDZ National Award Best House under 250m/2  2011

Brief
Make most of the site , optimize for sun and view to Dunedin.
 
Site
NW  orientated site with extensive views down the Otago Harbour. 12 deg slope. Large site but small building platform
Context
The object was to produce a passive  solar house that required  minimal additional  heating and maximized the view to the SW.  A hill to the NE  made this  difficult to achieve as  sun rise mid winter  is 10.30a.m.
Details
The linear nature of this house allows all  rooms to benefit  from both sun and views down the harbour to Dunedin city . No windows  to the earth-bermed south wall to maximize  heating efficiencies while reducing heat loss. Projected Annual heating load from April to October  at 20 deg 24 hours is 4250 kwh. At 16deg it is zero. Data recorders show that the winter 7.00am  indoor temp average was 16 deg.- only occasionally dropping below this. Solar water collectors along with  a lighting load of 500w  translates to power bills  of $60.00 summer,$100.00 winter. Total Power consumption 3500kWh Pa.
A simple pallet of  exposed block, conc floor ,macrocarpa, and neutral paint complete the house.

No house should ever be on a hill or on anything. It should be of the hill. Belonging  to it. Hill and house should live together each the happier for the other.
