5th AVENUE-GRAND 18 ROOM RESIDENCE. A truly unique opportunity to own one of the most important prewar residences in Manhattan in one of Fifth Avenue's most prestigious cooperatives. There are three apartments on the 7th floor which can be re-combined, and reconfigured back to the original 18-room layout as designed by J.E.R. Carpenter in 1915. With 50-feet fronting Central Park, this gracious residence would incorporate 5 bedrooms, 3 woodburning fireplaces and would enjoy glorious light streaming in from 30 windows, spanning 4 exposures. The space would have 10'8 ceilings accentuated by traditional moldings, tall doorways, and original hardwood flooring throughout. A stately 37-foot gallery would lead to the formal entertaining rooms, which include a corner 30-foot living room with 4 large casement widows, pristine herringbone flooring and a woodburning fireplace with a hand-carved marble mantel. The formal dining room, featuring exquisite woodworking and built-in bookshelves may be accessed through double-doors off the living room, or off the gallery. There is also a handsome library with a fireplace and 2 windows overlooking East 72nd Street and a powder room. There is an eat-in-kitchen with custom cabinetry, granite countertops and ample room for dining, as well as a large butler's pantry and a separate laundry room. Along the Southern wing of the home, there is a 22-foot family room, with a fireplace, as well as a 16-foot home office. The master bedroom suite enjoys Central Park Views and has a luxuriously-appointed marble master bath with double-sinks and a large walk-in closet. There are 4-5 additional bedrooms and 4 full-baths.Constructed in 1915, this distinctive limestone-clad, Italian palazzo-style apartment house was designed by legendary architect J.E.R. Carpenter. It has a canopied entrance on 72nd Street and a central court. In a florid Italianate character, the levels of the four-story rusticated base and the top portion of the structure are highlighted by horizontal coursings of balustrade, escutcheon ornamentation, dentil molding, and other Classical motifs. Quoins embrace the corner of the building to the roofline, which is flat and emphatically crowned at the eaves by a projecting cornice adorned with lion heads, rosettes, and brackets. Rich in decor and arrayed with a coffered ceiling, the building has a remarkable lobby featuring an elegant stone staircase. 907 Fifth Avenue was the winner of the 1916 Gold Medal Award of the A
