PASSIVE HOUSE CLASSIC

St Clair Dunedin

41,660 KG

94%

This amazing home sits south west over the coastal view. The architects had to solve the issue of being able to enjoy the vista while enabling some shelter from the prevailing winds. Super insulation was used along with Triple argon filled low-E coated glazing necessary for the climate this far south. European windows by ecoWindows in wood and aluminium also feature. This grid tied photo-voltiaic home is perfect for this progressive family, often generating more energy than it uses.
