Perched high atop a distinguished pre-war co-op in a prime Upper West Side location, this exquisitely renovated penthouse boasts spectacular views and a private 600 square foot wraparound terrace. Designed by acclaimed architect David Montalba, no detail has been overlooked in the masterful reinvention of this home. Ceiling heights of nearly 12 feet and an expanse of white oak chevron flooring lend a sense of grandeur to the space, perhaps best amplified by the monolithic slab of marble surrounding the wood-burning fireplace in the living room. Ingeniously conceived bookshelves conceal structural supports and create airy transitions between rooms. The sleek, windowed kitchen, fitted with a suite of professional-grade appliances, is a work of art and a chef's delight. The dining room, with its floor-to-ceiling bookcases and library ladder, gives a contemporary nod to Billy Baldwin's iconic concept.

The primary suite makes full use of every square inch, offering a rare abundance of closet space and a sumptuous, windowed bath that includes a soaking tub and rainfall showerhead. The second bedroom includes an en-suite bath and cheerful western exposures overlooking the terrace. This home also includes a gym, central air conditioning, and additional storage.

Designed in 1924 by preeminent architect Emery Roth, 243 West End Avenue is a full-service co-op that offers residents a 24-hour doorman/concierge, resident manager, porters, laundry facilities, storage lockers, and bicycle storage. The 1, 2, 3 subway stop, Trader Joe's, and Riverside Park are a block away, not to mention some of the finest shops and restaurants on the Upper West Side. This co-op has a very reasonable sublet policy and allows gifting and co-purchases. Sorry, no dogs allowed.
