Stretched over 27 vertical feet of the top two floors of this prime Gramercy Park co-op, the opportunity to create a townhouse in the sky beckons. Proposed architectural plans from Israel Peles Architects will be provided for the buyer to combine two units to create a dramatic duplex residence with 3-bedrooms, and 4-baths. In addition, the proposed floorplan includes a sweeping floating staircase, new fenestration, a laundry room and abundant closet space. The plan retains the home's two existing wood-burning fireplaces, which imbue the living room and master bedroom suite with warmth and ambience. The solarium and terrace with panoramic city and park views on the upper floor will also remain intact. Dramatic in any incarnation, the architectural plans included in the sale capitalize on the space's three exposures and uncommonly grand ceiling heights, but can easily be customized to suit the most exacting tastes. This is a rare opportunity to create a thoroughly unique space within one of Manhattan's most coveted addresses.
