The retreat’s southern exposure maximizes sunlight with 24 feet of floor-to-ceiling windows. The sun’s warmth is absorbed and stored in the concrete floor, keeping the interior warm. Combined with thickly insulated walls, the cabin requires little additional energy, and has gone up to three days in winter without any electrical heating.
