Overview of Sackett Union at 291 Union Street

Sackett Union is a distinctive seven story condominium development at 340 Court Street in Carroll Gardens, Brooklyn, that represents an intriguing evolution from controversy to architectural success. Originally conceived by the Clarett Group as a black high rise tower, the project was redesigned by Alchemy Properties and Rogers Marvel Architects after community protests, resulting in a more contextual seven story building with a brownstone colored façade and setback upper floors that maintain the neighborhood's townhouse street profile.

The complex showcases modern interpretations of traditional townhouse themes through its varied architectural elements, including different colored façades (some angled), a mix of stoops and step down entrances, protruding multi level window surrounds, and a striking two story high corner window. The building features battleship like volumetric massing with alternating light and dark brown panels, red brick sections, and pale orange vertical accents that create visual diversity. The development uniquely combines 32 condominium apartments with 11 townhouses (four single family units on Union Street and seven two family units on Sackett Street), offering residents multiple housing typologies within a single project.

Apartments range from two to four bedrooms, with select duplexed units and maisonette style residences featuring private entrances and substantial outdoor space. Notable units include a 22 foot wide maisonette with its own backyard and a townhome at 294 Sackett Street spanning 3,210 square feet across four levels with over 1,000 square feet of exterior space. Standard apartment features include white oak wide plank flooring, chef's kitchens with Wolf ranges and Sub-Zero refrigerators, five fixture master bathrooms with marble floors and soaking tubs, and in-unit washers and dryers. The building provides full service amenities including 24 hour desk attendant, state-of-the-art fitness center with Peloton bikes, children's playroom, furnished roof deck with Manhattan and Brooklyn views, and parking garage with select residences including deeded spots. Residents also benefit from a 421-A tax abatement through June 2027.
