***Convertible 3 bedrooms plus office*** (Alternative floor plan available) Imagine a classic loft space with soaring ceilings, oversized windows, and cast iron columns, located in an architecturally significant building. This corner unit has breathtaking features, a flexible floor plan, and is a slice of New York history.Currently configured as a two bed with two full baths. The foyer opens up into a great living area with 13ft+ ceilings supported by two impressive Corinthian columns. The exterior walls are lined with 10 massive double-hung, double-pane, mahogany windows which face South and East. Solid hardwood blankets the floors. In the generously proportioned master suite, a king-size bed might feel inadequate. The ensuite bathroom features antique-y touches that echo the building like a marble jack-and-jill sink, classic plumbing fixtures and mirror cabinets, and a pair of free standing cabinets for more storage. A large walk-in closet off to one side completes the trifecta. The thoughtfully conceived kitchen, which is open to the living area, is a centerpiece fit for a master chef or a master host. Along the back wall is the Viking gas range and convection oven with vented hood, Miele dishwasher, and full size Sub-Zero refrigerator. Ample storage. Building amenities include central laundry in the hallway (in-unit laundry allowed), three elevators, full-time staff, video intercom, bike storage, package room and storage available for rent, and a shared landscaped roof deck with panoramic views of downtown. Pet friendly. Fios available. The Potter Building, as 145 Nassau is known, was once one of several buildings along Park Row once called Newspaper Row and once housed the New York Observer and the Otis Elevator company. The architect, Norris G. Starkweather, brought a mix of styles, predominantly Queen Anne. The developer was real estate magnate and Congressman Orlando B. Potter. The Potter Building used fire resistant construction and was considered the most fire-proof building in existence. Structural steel was encased in terra cotta, walls were built with brick, beams of rolled iron, and internal columns of cast iron. The ground floor walls were made 40 inches thick and the exterior of the first two floors were made of cast iron. The rest of the exterior was covered in ornately detailed terra cotta. It is today considered on the finest examples of sculpted terra cotta building remaining, and was landmarked in 1996.
