On the shores of Sebago Lake, nestled in a grove of Eastern white pines, we designed a year-round camp to accommodate a family who has been coming to this site for generations. Our design takes advantage of the surrounding natural beauty, with walls of south-facing glass overlooking the lake and materials selected to blend in with the environment. Working with a limited footprint due to zoning restrictions, we created a floor plan that is compact and efficient but feels spacious: living areas on three floors are organized around a central staircase and spaces are designed to multi-task. Interior and exterior flow together seamlessly; the same posts and beams from outside are repeated inside, and beige board-and-batten siding and gray-green shingles blend with the wooded site. Although rustic in appearance, the camp functions with high efficiency and low maintenance. The family fittingly calls it "Porta Panagia," Greek for "Gateway to Heaven."
