Description
330 Union Street - A Home with History in Carroll Gardens For the first time in 60 years, 330 Union Street is ready for its next chapter. This four-family Brick Townhouse has been home to a local artist who designed wedding gowns for neighborhood brides. Alongside her husband, she worked jointly on building and decorating miniature dollhouses, which were lovingly displayed in their front window for all the passersby. Their creativity and craftsmanship brought joy to the community, making this home a true part of the neighborhood’s fabric. Offering 3,200 sq. ft. of living space plus a full dry cellar, this residence is currently configured for both owner occupancy and rental income, with a flexible layout and plenty of potential. With north and south exposures, tons of natural light fill the home throughout the day. Key Features: • Garden Level: A floor-through apartment with a decorative fire place and a garden room—ideal for canning, storage, or preparing for the spring planting season. Direct access to the backyard. • Parlor Floor: High ceilings, oversized windows, and a deck with stairs leading to the backyard. • Backyard Space: A spacious 20’ x 60’ backyard, offering endless possibilities for gardening, entertaining, or relaxing. A shed at the back of the house provides additional storage or creative workspace. • Third & Fourth Floors: Two floor-through apartments, each with a one-bedroom layout and an additional side room. Additional Highlights: • A full dry cellar with a washer & dryer, storage room and utilities. A large hallway skylight that brings abundance of natural light. Additional FAR available. Building will be delivered vacant. This home offers a chance to restore or reimagine a piece of Carroll Gardens history. Carroll Park is just around the corner, providing green space, a playground, and a true neighborhood gathering place. The area is known for its independent bookstores, pottery studios, yoga studios, and excellent dining. The farmer’s market is just two blocks away, and the F & G trains are one block from your doorstep, making commuting easy. 330 Union Street is ready for someone new to make it their own! Property is being shown by appointment only through Open House by listing agent. Some photos are virtually staged.
