Here’s why a spiral staircase was the perfect addition to this edgy house

Architect Vaughn McQuarrie shares design insights from an industrial Waiheke home, highlighting its unique spiral staircase. Originally planned in steel, the staircase was finished in unpainted plaster to soften the interior and act as a sculptural feature.

This decision complements other key choices, such as embedding the house into the slope to avoid deck balustrades. The design also features enormous, unsplit windows that lighten the structure's appearance and create a suspended floor effect from the inside.
