Architect Vaughn McQuarrie has replaced a 1920s cottage on New Zealand's Waiheke Island with a modest concrete and timber residence, set among mature gardens.

McQuarrie was asked to design Oneroa House for a client who has spent 26 years residing in the cottage on the edge of the island, located around 20 kilometres off Auckland's coast.

"The owners had lived on the site in a 1920s cottage for the past 26 years; the cottage was beyond repair however the site has grown up around it," explained McQuarrie, who set up his practice on the island in 2009 after a decade working in the UK.

"In order to take advantage of the existing established planting, the new house was designed in a similar position to the cottage, incorporating the original large concrete water tank," he added. "The house opens up to views to the east of the sea and west to the garden. Neighbouring properties to the north and south are intentionally 'blinkered'."

Two mono-pitched roofs lift up from the main body of the 104-square-metre house to make room for north-facing clerestory glazing. This brings light down into the kitchen and a snug, but prevents spaces being overlooked by a neighbouring property.
