Montana and New Zealand share breathtaking mountains and pristine water. The owners of the Kiwi House love both places and sought to build a residence that supported an active lifestyle, was about minimum size and maintenance, and of maximum quality. Claiming only 823 square feet of land, the house looks to the sun, gathers around a hearth, and creates a solution that is energy efficient and comfortable. The house was constructed on a bustling urban infill site. In response, exterior public-facing walls were constructed of carefully detailed Montana stone, while other walls were clad with reclaimed redwood and metal. A small floor area, super-insulated construction, and photovoltaic panels effect budget-friendly utility bills and actually fuel the grid when the owners are away.
