The apartment, measuring just over 400 square feet, opens into the kitchen, which architectural designer Alan Y. L. Chan outfitted with a Dornbracht faucet and a sink of his own design. The black steel backsplash doubles as the back of a built-in bench on the other side. A concrete “ribbon” serves as the main design concept and the countertop, and continues throughout the apartment. A built-in LG refrigerator is located just across the concrete floor at right. Image courtesy Brian Riley.
