While the exteriors of the house display drama, the interiors are relatively sombre in nature. “Interiors are articulated and finished to enhance the expansive and overlapping relationship between spaces. A limited palette of whites and light woods are carried throughout the interior. Details throughout leave corners open to imply interlocking spatial relationships,” says Mark. The house was built for a modest $80 per square metres, keeping a sustainable, low-cost concept — a policy that echoes the architect’s belief, “We gained other economies by using off-the-shelf readily available materials and fixtures. The minimal footprint reduced foundation costs, which are at a premium in Arkansas because of the unstable soils. We also collocated utilities in the layout to minimise costs for mechanical, electrical, and plumbing distribution costs,” he says. A house like this is sure to rouse neighbour’s curiosity, “Following the completion of the Mood Ring House, nearby homeowners have begun to equip their porch lamps on with multi-coloured LED bulbs, transforming the neighbourhood into a Rainbow Light District!” says the architect.
