Project Information

This contemporary ADU blends naturally into any New York City backyard with a clean, neutral façade designed to complement a wide range of existing homes. Its refined silhouette and understated character create a modern yet welcoming presence. Inside, the design continues with a contemporary feel enhanced by a subtle splash of sage, adding warmth and individuality. The layout is carefully planned to maximize living space by situating the rooms along one side. Together, these elements create a thoughtfully designed dwelling that balances refinement with versatility.
