The brief

Glendhu Bay sits at the western end of Lake Wānaka, ringed by alps. The original 1980s home had a tired aluminium envelope; the owners wanted to keep the house but change how it met the view. We replaced eleven openings with W40 — the everyday suite — and the room turned inside out.

The work

How it came together.

The drawings called for full-height French doors on the lake elevation, paired with a run of casement windows over the kitchen bench. W40 was the right suite — slim enough to keep the proportions delicate, deep enough to take a 22mm IGU. The whole package fitted into the existing aluminium reveals, which kept the renovation contained to within the building line.

The owners had a tight budget. We worked with the design team to find the right reduction — a single fixed window in the bathroom in place of the original casement — to get under the line. The eleven openings landed at exactly the agreed number.

Six weeks of fabrication, three days on site for install. The original kitchen joinery was kept; the casement above the bench was sized to match the existing reveal exactly so no carpentry was needed.

“They told us, in our first call, our budget would not stretch. Then helped us scope a smaller package that did. Wholly unusual.”
