411 Union Street is a charming four-family townhouse located on a picturesque tree-lined street in the heart of Carroll Gardens. This nearly 20’-wide property sits on a 90’ lot and is surrounded by 52 townhouses on all sides allowing natural light to flood this home at all times of day. On four levels plus a storage basement, 411 Union is approximately 3,093 square feet with a maximum buildable size of 3,480 square feet. The large forecourt at the front entry allows for privacy setback from the street. The tall stoop offers grandeur; while the front garden offers an opportunity to landscape. Each of the four apartments can be delivered vacant offering the future owner the opportunity to convert into a single-family home, live with income, or use it as an investment. The garden apartment is accessible from within the parlor hallway as well as via egress below the stoop. An open layout allows natural light to flow through the space seamlessly, with private access to the north-facing garden. Original tin ceilings line this apartment. The second and third-floor units each feature floor-through one-bedroom apartments with multiple closets and period details intact. The top-floor one-bedroom renovated apartment includes a home office and views of downtown Manhattan in the back. The top-floor unit features custom white cabinets, a quartz countertop, stainless steel appliances, marble flooring, and a large window that fills the space with natural light. The bathroom is elegantly designed with white and gray marble tiles and modern fixtures. Throughout the unit, you’ll find exposed brick details and excellent closet space, making it both stylish and functional. Ideally situated, 411 Union Street is just one block from the vibrant Smith Street and two blocks from the F/G subway lines, offering both convenience and a serene residential feel. Ideal uses for this prime townhouse include conversion to single-family like many of the neighbors, live with income, or use as an income-generating free-market townhouse.
