Perfectly situated just off Fifth Avenue on one of the city’s most prized townhouse blocks, this stunning 20’ wide brownstone has approved plans from the Department of Buildings and the Landmark Preservation Commission for the addition of a 6th floor, an 8 foot expansion on all floors towards the garden, and the excavation of the basement. The approved plans also include vast windows on the back of the house, bringing additional light and garden views into the 7,800 square foot home. The house is delivered ready for work to begin. A spectacular design by Steven Harris Architects includes dramatic entertaining spaces, extensive family areas, a sophisticated master suite, seven additional bedrooms, four fireplaces, a roof deck, a soaring staircase, and an elevator. 12 East 78th Street offers the rare opportunity to create a magnificent single family residence in the heart of the Upper East Side.
