Mountain Retreat is a stone and concrete cabin dug into a hillside in the mountains of New Zealand’s South Island. It was designed by Fearon Hay Architects as a year-round retreat for a young family. The entry approach to the small cabin is from above, with only the gravel-covered roof visible. Suddenly a stone staircase appears, leading visitors down to ground level on the downhill side. The low boxy form of the building is visible from there, appearing like a fortified bunker set into the slope. Clad with roughly textured local schist stone, the cabin blends into the rugged landscape.
