Description

Own a piece of history! This fully furnished 1 bedroom unit is located in a landmark condo building at 21-23 South William Street known as Block Hall. Unit 4C is beautifully renovated with an open kitchen boasting a Viking stove that vents out, Liebherr refrigerator, and Miele dishwasher as well as granite countertops and tons of storage. 10 foot high ceilings and a Juliet balcony (that gives a peek of the East River!) in the living room let in excellent light and air with a South/East view. The king-sized bedroom, also with 10 foot high ceilings, will allow many furniture configurations and has a large walk-in closet. Block Hall has all the charm of a pre-war building with the finishes and conveniences of a new condo. It features a gorgeous furnished rooftop terrace with water views, laundry on every floor, fitness center, virtual doorman, and daily on-site super and porter. Originally a private club built in 1927, Block Hall is a Tudor-style landmark building which was converted to condominiums in 2005. The building is located in the heart of all the attractions that the financial district has to offer and has a private back entrance to Stone Street with its famous pubs and outdoor dining. If that wasn't enough, a 421g tax abatement until 2021 and low common charges make this a great investment or primary home. Contact exclusive listing agent Andrew Mak at the Corcoran Group for a private showing at one of the most unique residences in NYC!

The Financial District occupies the southern tip of Manhattan, where landmark office towers have been converted into spacious residential lofts alongside new luxury high-rise condominiums with river and harbor views. The Oculus and Fulton Center transit hubs connect over a dozen subway lines, including the 2, 3, 4, 5, A, C, J, and Z trains, making it one of the best-connected neighborhoods in the city. Battery Park, Bowling Green, and the 9/11 Memorial provide open green space and waterfront access at the foot of the skyline.
