The site floods. Instead of fighting the tide with walls, the house is lifted on slender steel legs so that the inlet runs under the living room. At high water the house appears to float; at low water the mudflats become its garden.

The plan is a long bar, one room deep, so every space has water on one side and bush on the other. Sliding screens of cedar batten control glare and privacy from the boats that pass at the weekend.

The structure was prefabricated in Hamilton and installed in six days from a barge.

Approach

Design for the water, not against it. The tide sets the section.

Prefabrication kept the site untouched: no excavation, no concrete beyond the piles.
