New York, NY

This new seven-story condominium building has a duplex maisonette at its base, and floor-through apartments above. The massing of the building street facade reflects the scale of the townhouses along this quiet Upper East Side street. This building is equipped with a geothermal well that provides heating and cooling without rooftop condensers or a central boiler room. As a result, the rooftop is unencumbered with mechanical equipment providing a valuable amenity for the penthouse apartment.
