HISTORY AND BUILDERPositioned on a 25' x 60' lot on the southwest corner of Desbrosses and Greenwich Street, 452 Greenwich (aka 21 Desbrosses Street) was originally built in 1819 as a two and a half story building by Alexander Thompson, occupied by Scottish settler Archibald Sommerville. The house was raised to a four-story residence in 1852 by the building's second owner, William B. Howenstine, in a Federal style with numerous brownstone additions. Later in 1903, the third owner, New York County Sherriff William F. Grell, would add a restaurant to the ground floor and use the upper levels as a residence.Nearly 200 years later, this residence has been transformed into a state-of-the-art single-family home made unique by several uncommon characteristics, most notably a 25 foot width with a corner position facing north, a single-car garage with legal curb cut, and an extraordinary rooftop garden providing an urban oasis with open north Tribeca views.THE RESIDENCEFrom the main entry on Desbrosses Street, a grand front hall of porcelain tile sets the tone of elegance and craftsmanship for this expertly renovated single-family residence. To the east, a large billiard room with windows facing east and north, high ceilings, and a full bath making this a possible guest bedroom or library. To the west, a windowed office with storage space could be easily converted to a mud room for bikes and all-season gear. The truly invaluable single-car garage, large enough to accommodate a variety of vehicles, has been outfitted with vast amounts of custom storage space.
