This inward looking city residence intrigues passersby with its alluring use of masonry, weathered copper and steel. Beautifully bathed with natural light, this 8,000 square foot residence has extensive floor to ceiling windows and doors. Located in an older part of the city, the ground floor is three feet below street grade, and features a spacious private courtyard. The granite patio adjoins multiple rooms with walkout access to its tranquil setting. The living room features a generous lay light, a 14-foot ceiling and aged copper panels. Custom millwork, integrated with built-in cabinetry, runs throughout. Hydronic radiant heating, supplied by a geothermal system, warms the end-grain block and granite tile flooring. Designer lighting and “smart-home” technology create a modern yet warm aesthetic. Cor-Ten steel fencing frame its serene landscape.
