Project Revisit: Karangahake House

Built in 2019, the silvered patina of the Tundra weatherboards at Karangahake House in the Kaimai Ranges is proof of the effectiveness of Abodo’s naturally derived silicate coating.

This Make Architects-designed, NZIA award-winning home has now been standing for three years, making it an excellent test of the success of the silicate coating that was applied to its Abodo Tundra weatherboard cladding.

After exposure to rain, frequent fog and sun in this temperate climate, the Tundra timber has silvered off to a tone that merges beautifully with the forested and tussocked surroundings of this rural property, as well as with its pale grey steel roof.

While it starts life in a pleasing warm timber tone, the weathered grey patina that Abodo’s silicate coating takes on over time is often one of the main reasons it is specified - the other being its low maintenance qualities. Silicate is used a to create a protective shell, which can last for up to 7 years without requiring a re-coat depending on exposure conditions. The speed at which the even, silvered look is achieved depends on exposure to weather, but in most climates, it is well on its way after a year.

For this home, time has only improved the backcountry hut aesthetic that the architects were aiming for in its design - and for the homeowners, the ability to sit back and let the finish synergistically work with the naturally durable Tundra Cladding, means they are able to enjoy their house without the stress of constant maintenance.

Before and After: Once silvered off, the knots and inherent blemishes in the Tundra timber lend a natural appearance to the home.

After three years, the colour of the weatherboards now merge with the roof and appear at one with the rural landscape.
