Rare Single-Family with Garage & Redevelopment Potential in Williamsburg!

This rare single-family home with a private garage offers over 3,000 SF of space across 3 levels, perfectly suited for an end-user seeking comfort and flexibility, or an investor looking for long-term upside.

The property is comprised of approx. 2,488 sq. ft. single-family residence and a 520 sq. ft. private garage, which is a rarity in Brooklyn. Spanning 3 levels, the home features 4 bedrooms and 3.5 bathrooms with thoughtfully designed living areas. The open concept main floor offers a sun-filled massive eat-in-kitchen and dining space. The living room is elevated four stairs up from the kitchen. On this same level, there are also 3 generously sized bedrooms with 2 full baths. The upper level, with its half bath and terrace over the garage, can serve as a 4th bedroom, home office, or recreational lounge. The lower level adds even more versatility with space for a family/media room, gym, or studio, and is also ideal for those who want a live/work lifestyle.

Beyond its residential appeal, 21 Thames offers significant investment potential. Property needs some TLC. The building will be delivered vacant, providing an excellent opportunity for an owner-user to occupy immediately. The site allows for up to 4,000 buildable sq. ft., with over 2,000 sq. ft. of unused air rights, making future redevelopment or expansion a real possibility.
