This exceptional five-bedroom, four-and-a-half-bath residence at The Marquand has been masterfully crafted by Shelton, Mindel & Associates to exude classic Upper East Side grandeur. Comprising 3,847 square feet, the residence's sprawling open layout, grand proportions, 10'ceiling heights, and abundance of oversized windows create an unparalleled sense of space and light. A private elevator opens to the elegant entry foyer, where an adjacent wood-paneled gallery leads to the gracious corner living room with three oversized windows, including an enormous bay window, flood the space with ambient light and frame picturesque views of both 68th Street and Fifth Avenue. A double-sided wood-burning fireplace sculpted in Travertine marble adjoins the corner dining room, also with multiple exposures and an oversized bay window. The open eat-in contemporary chef's kitchen with center island, Bulthaup cabinetry, and appliances by Sub-Zero, Wolf, and Gaggenau features west-facing exposures overlooking iconic Fifth Avenue, and flows seamlessly to the adjacent windowed family room with media niche, concealed A/V closet, and Travertine marble wood-burning fireplace. In the south wing, the master suite comprises a sun-flooded bedroom with enormous bay window, a windowed corner sitting room, lavish private dressing room, and windowed master bath with onyx walls, his-and-hers vanities, freestanding soaking tub, and separate glass shower. Three additional windowed bedrooms are each grand in scale; bedroom two offers a windowed en suite bath, while bedrooms three and four are joined by a windowed Jack-and-Jill bathroom with freestanding soaking tub, separate glass shower, double vanities, and private water closet.  Private service quarters, including a separate service elevator and hall, spacious windowed bedroom, and en suite windowed bath, facilitate seamless entertaining and luxurious daily living alike.
