The northern and eastern facades of the long pavilion structure are entirely glazed and sit under a high eave. This layout encourages winter sunlight to penetrate the interior living spaces and warm the internal thermal mass. Conversely, in the summertime, the operable aluminium venetian blinds on the exterior block the light from entering and allow the insulated concrete floor and RVB walls to keep the interiors cool.
The all-important RVB wall is situated on the southern façade and consists of a three layered system. Beginning from the outside-in (and much like a lot of his other projects), Murcutt chose corrugated aluminium from Alucobond to make up Magney House’s external skin. Next a small cavity zone was formed with 37mm battens and filled with Insulwool 75 insulation. The final layer of the system is the painted single brick interior skin—the thermal mass.
