A world-class energy-efficient design defines this home on a rural lifestyle block north of Hamilton. The collaborative design with Edwards White Architects ensured the home treads lightly on the environment despite its generous 252 sqm footprint. Computer modelling before construction used local climate data to ensure ultimate thermal performance. The Euro from eHaus is built to the German PassivHaus energy-efficient building standard, the highest on the planet. The four-bedroom, two bathroom home is north facing for ultimate solar gain. Two living areas spill onto a spacious deck. The contemporary black brick and cedar, tie in well with modern designer kitchen, scullery, bathroom and laundry. German-engineered joinery, a solar photovoltaic system, hot water and ventilation systems and heat-pumps, plus airtight construction make this a star.
