This month 'All About Architecture' explores a project in Western Australia that utilises products manufactured by Australian Architecture Association sponsor - Kingspan Insulation. Multi-Award Winning 'Bedfordale House' was designed by Suzanne Hunt Architect and built by Gransden Construction, with Kingspan Insulation playing a pivotal role in bringing the residential masterpiece to reality.

Winner of the 2015 HIA Australian Home of the Year Award, as well as the Australian Custom Built Home of the Year Award, ‘Bedfordale House’ is a Japanese-inspired 864 square metre masterpiece set in a semi-rural suburb in southeast Perth.

Every element of this energy-efficient, multi-zonal residence was hand selected to deliver world-class aesthetics and performance.

With a heavy emphasis on raw timber and stonework, the sleek and uncluttered lines of the construction and its interior design called for a subtle insulation treatment to maximize internal space and retain the simplicity and lightness of the walling. The solution was Kingspan Kooltherm® K8 Cavity Board supplied by Kingspan Insulation.

These incredibly efficient, narrow-profile rigid insulation boards occupy little lateral space, and they deliver higher thermal performance than any other commonly available cavity insulation product. Thanks to the minimalist characteristics of the Kingspan Kooltherm® K8 boards, Architect Suzanne Hunt, from Suzanne Hunt Architect, and builder George Allingham, from Grandsen Construction, were able to harness the full simplicity of the Japanese design and achieve energy efficiency targets without large wall cavities.

“Our Bedfordale project introduced unique challenges,” says Grandsen’s Managing Director George Allingham. “We didn’t have the conventional cavity area available – the design called for a brick surface interior and an exterior clad in 200 mm drybed basalt, quarried in Bunbury. Our stonemason hand selected 220 ton of stone to site. We needed to achieve the best possible thermal block in the limited cavity area; Kingspan Insulation worked closely with us to identify the best possible solution.”

The home, positioned on a 20 hectare property bordering Albany Highway, has premium functionality to match its gentle aesthetic taste, which means the owners will be perfectly placed to enjoy the indoor-outdoor spirit of their dwelling year-round.
