Arkus were approached to design a flexible office space that can easily be reconfigured, so they developed an floor plan of 4 expandable blocks divided by “green” entrance service cores. A double roof system with an air flow cavity helps reduce solar gain, while west-facing thermal mass fins absorb heat and stabilize internal temperatures in the office space throughout the year. Natural stone walls, green walls, green roofs, timber, off-shutter concrete, and steel portal frame structures provide a rich mix of materials. The home’s vegetated walls are used for insulation purposes and to ground the building within the surrounding grassland landscape. Numerous passive design techniques were explored within the building, using the natural vegetation to ground the building to the site.
