As part of the rehabilitation process for a five-unit Victorian apartment building, originally constructed as a single-family home in 1875, this project in San Francisco's stylish NOPA neighborhood involves transforming a dark and cramped 850-square-foot attic apartment from the 1940s into a contemporary, light-filled, 1000-square-foot penthouse with three bedrooms and two baths. The addition of dormers and reconfiguration of partitions expanded the usable floor area, while removing the original flat ceiling created a more spacious atmosphere. Strategically placed skylights maximize natural light and offer stunning views.
