Property Details
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!
