The project rethinks middle-class housing by making the backyard the center of block life, with accessory buildings serving as flexible infill on underused lots. Circulation within the block and buildings drives the design. A central core organizes units, while interior stairs enable smooth transitions between indoor and outdoor spaces, and a “bonus” half-floor fits within the three-story limit. Staggered layouts create varied yards, balancing private and shared outdoor space, while open ground floors activate courtyards and connect to the street. Alternating zero-lot lines provide both privacy and future adaptability, and a final layer of community spaces—such as small classrooms or health services—supports multigenerational, resilient neighborhood living.
