Upper West Side Triplex and Rooftop Addition
Working with the Landmarks Preservation Commission and City Planning, SGS received a variance to build a rooftop addition for the triplex apartment on Manhattan’s Upper West Side. Two light-filled stairwells connect a series of open living spaces, leading up to the penthouse and roof terrace. Minimalist details, wood ceilings, and expansive glass walls blur the lines between inside and out on the penthouse level.
