Description

Built in 1899, 323 15th Street is a classic brick townhouse positioned on a quiet, tree-lined block in the heart of Park Slope. Rich in character, the home is defined by its timeless pre-war details and preserved original fixtures, with a sense of historic charm that carries beautifully throughout every room.
Currently configured as a three-family residence, the property offers exceptional versatility-easily adaptable as a one- or two-family home, or maintained as a high-income investment with strong long-term upside. Each full-floor apartment is well-kept, featuring high ceilings and oversized north- and south-facing windows that invite natural light to pour in throughout the day. The upper floors enjoy open views across neighboring townhomes and treetops, with subtle glimpses of the Brooklyn skyline in the distance.

The garden level presents a flexible sunken basement with windows at both the front and rear. The existing environment would allow an owner the potential to add media room, home office, gym, or recreation space.

Spanning approximately 2,421 square feet across three stories (excluding the basement), the home also offers the potential to expand by roughly 1,000 additional square feet, creating a compelling opportunity for added value.

Perfectly situated just moments from Park Slope's best restaurants, boutiques, and neighborhood amenities, and in close proximity to Prospect Park, 323 15th Street also offers convenient access to the F/G and N/R subway lines for an easy commute to Manhattan. A rare opportunity to own a timeless Brooklyn townhouse that seamlessly blends charm, flexibility, and future potential.
