Set on an extra-deep block, the home unfolds across approximately 4,000 square feet and is currently configured as an owner's triplex over a private one-bedroom garden apartment. Behind its handsome historic facade lies a residence defined by grand proportions, soaring ceilings, and the timeless character that makes Brooklyn townhouses so beloved. The owner's triplex begins on the gracious parlor level, where tall windows fill the living room with natural light and original details speak to the home's historic charm. A formal dining room creates an elegant setting for entertaining, flowing naturally toward the kitchen and out to a deck overlooking the garden below. It is a floor designed equally for lively gatherings and quiet evenings at home. Upstairs, the second and third floors offer a generous and flexible layout with multiple bedrooms and the potential for home offices, libraries, or creative spaces. The home's impressive 21-foot width allows each room to feel open and comfortable, a rarity even among Brooklyn townhouses. Below, the garden level is configured as a one-bedroom apartment with its own entrance and direct access to the garden, ideal for rental income, guests, or conversion into a spectacular single-family residence. The property will be delivered vacant, presenting a rare opportunity for the next owner to move right in, create a custom townhouse, or design the ideal live-plus-income configuration. Just moments from the cafés and restaurants of Vanderbilt Avenue, the cultural energy of the Barclays Center district, and the green expanses of Prospect Park, the location offers the very best of Brooklyn living. Multiple subway lines nearby provide easy access to Manhattan and beyond. ## Property Details - **Price**: $6,250,000 - **Potential Buyer Rebate**: $156,250 - **Bedrooms**: 6 - **Bathrooms**: 4 full, 2 half - **Living Area**: 1,050 sqft - **Property Type**: Residential - **Year Built**: 1910 - **Building**: 121 Street MARKS Avenue - **Neighbourhood**: Prospect Heights - **Area / Borough**: Brooklyn - **Subdivision**: Prospect Heights - **Listing Office**: Corcoran Group - **State**: NY ## Estimated Potential Buyer Savings Real Estate Rebate Team estimates potential buyer savings of up to **$156,250** at closing. *Estimated by Real Estate Rebate Team.
