High ceilings, oversized south-facing windows, and unusually generous proportions define Residence 4E at Block Hall, a spacious one-bedroom in one of the Financial District’s most distinctive historic buildings.
The large living/dining area with lofty ceilings offers the kind of scale that is increasingly difficult to find in a downtown one-bedroom. Three tall windows bring in excellent southern light and overlook the cobblestone, pedestrian-only stretch of historic Stone Street, removed from through traffic and cars.
Open to the living room through a large pass-through and breakfast bar, the kitchen offers extensive wood cabinetry, abundant granite counter space and a full suite of premium appliances, including a Viking range. Hardwood floors and high ceilings continue throughout the home.
The generously proportioned bedroom measures 15'3" × 10'11" and comfortably accommodates a king-size bed along with additional furniture. Two oversized windows provide further southern light, while a walk-in-closet offers excellent storage. The bathroom features a soaking tub, stone tile, a stone-topped vanity, and mirrored storage.
Laundry is located on every floor, immediately outside the residences, with two washers and two dryers shared among just five apartments. Please note that the washer/dryer is not located inside the apartment itself. Keep all of your closet-space, plus the convenience of laundry right outside your door.
Residents also enjoy a virtual doorman, secure package room, fitness room, elevator, and a beautifully landscaped furnished roof deck with East River and downtown views. A discreet rear entrance opens directly onto Stone Street, one of Lower Manhattan’s signature pedestrian-only cobblestone corridors, lined with restaurants and cafés.
Block Hall is an intimate 31-residence condominium occupying a striking Tudor Revival building in the Stone Street Historic District. Originally completed in 1927–28 as a private clubhouse, the building was later converted to condominium residences while retaining its distinctive historic character.
From here, Wall Street, the waterfront, Whole Foods, the Seaport, and an exceptional range of subway and ferry connections are all close at hand.
