30 Washington Street is a 7 story, 94 apartment rental built in 1930 as part of Robert Gair’s waterfront industrial complex in DUMBO. Originally designed by Benjamin Finkensieper, it was converted to residences in 2012 by Two Trees Management under David Walentas.
The conversion by WASA/Studio A retained the landmarked building’s industrial character. Its red brick exterior has metal tie backs, subtly arched window openings and a setback rooftop addition approved by the Landmarks Preservation Commission.
Apartments have high ceilings and large multipaned windows, and many retain substantial wood columns and exposed beams. Homes range from roughly 500 to 1,200 square feet, with dedicated home offices recurring in the layouts; several upper floor residences extend to large terraces. In-unit laundry is standard.
The building has a roof deck with grills and views of the Manhattan and Brooklyn Bridges, along with a fitness center, children’s playroom, bicycle room, resident storage and a live-in superintendent. It sits on a cobblestone street beside Brooklyn Bridge Park, close to the East River and Jane’s Carousel, with the Manhattan Bridge framing the surrounding streetscape.
Two Trees Management, founded by David Walentas in 1968, is a family-owned Brooklyn real estate firm known for transforming industrial waterfront neighborhoods like DUMBO and Williamsburg into vibrant mixed-use communities with amenity-rich rental apartments.
