This house included the restoration of a historic brownstone façade and the re-installation of a previously removed brownstone stoop. The rear façade features modern detailing with a large double height glass opening and a Klearwall, triple glazed, glass corner window.

The interior of the house has an open concept, which makes the 18-foot-wide house with elevator and elaborate staircase feel quite spacious. The second floor of the house is fully dedicated to the master suite, and the third floor features a multifunctioning space with large, 10 foot wide floor-to-ceiling pocket doors.

The elevator gives direct access to the roof bulkhead and opens onto a roof terrace designed for outdoor living. The entire mechanical system consists of one Zehnder ERV and one 3-Ton Mitsubishi City Multi condenser. This townhouse provides the energy efficiency of a Passive House with no sacrifice to high end luxury living.
