It’s been a long road to their “forever home” but the wait for this newly certified Passive House just north of Wellington has been worth it. Work began in 2016, but the subdivision and gaining title dragged on and then Covid created unforeseen delays. But all’s well that ends well. The four-bedroom 187m2 home shelters multiple generations. It sits on …

Brokenshire House

This dramatic Christchurch home, nicknamed ‘The Lighthouse’ by neighbours, has just been certified as a PHI Low Energy Building. It’s a stand-out for many reasons; on a technical level, it’s notable for its use of panellisation on a challenging site with a 35% slope.  A house on the site was extensively damaged in the Canterbury earthquakes and had already been …

The result is an appealing home full of surprises and perfectly suited to the needs of its family.

HCC Staff Facilities

It’s confirmed: New Zealand’s first non-residential building has won PHI-certification. Hutt City Council’s facilities building at Silverstream landfill is a Low Energy Building. The climate (30km north of Wellington) doesn’t present undue difficulties but the small building does face some intrinsic challenges. Its footprint is a simple shape, but the form factor sits at a very high 4.1 due to …
