Anchoring the northern end of prestigious Beekman Place is this tastefully renovated pre-war four-bedroom duplex penthouse with an expansive terrace affording panoramic river views.   The honed marble gallery leads to the formal dining room.  The living room has a charming WBF and a private book-lined study which would make an efficient and private home office.  Off the living room is a library, flooded in eastern and southern light, with a closet and full bath, making it an ideal guest suite.  The country kitchen, is complete with a large center island, and butler's pantry.  Also on this floor are two family bedrooms with a shared bath, laundry, and ample closet space.

Upstairs, the third family bedroom and bathroom open onto the central upper hallway.  The master suite, with bathroom and ample closet space, enjoys wonderful eastern views toward Roosevelt Island, and French doors opening onto a private southern terrace.

The deep, set-back terrace is ideal for entertaining, and is accessed directly off the upper hallway where there is an entertaining area with counter, cabinetry and refrigerator.  There is also an entrance on this level, so guests can step onto the spacious terrace, with separate areas for dining and entertaining.

439 East 51st Street is an intimate white-glove, pre-war cooperative built in 1929.  It rests at the entrance to Peter Detmold Park, a lovely quiet park which overlooks the East River.
