Designed by Ben Brady of Linetype Architectural, the home was built opposite a river in a flood management area on an unforgiving narrow site with a high ground water level.
It won the supreme award for a new residential home between 150m2 and 300m2 at the NZ Architectural Design Awards.
Built on stilts with raised decking and an open subfloor for drainage, it was built for a retired couple who had moved from a lifestyle block and wanted a house that was easily accessible with good building performance.
"Throw in a custom steel screen for privacy on your raised deck and maybe a wharf for a rainy day," Brady said.
"When you peel back the engaging and pleasing skin of this building, underneath you find the solid bones of a set of well-understood, eco-friendly technologies and design solutions. Out of the swamp has risen a sophisticated but unassuming beauty," they said.
