7 Saint Marks Avenue

A rare offering in the heart of the Park Slope Historic District, 7 St. Marks Avenue is a striking 23-foot-wide Gothic Revival townhouse distinguished by its bold brick façade, architectural provenance, and exceptional scale. Currently arranged with an expansive owner’s triplex occupying the upper levels and a private two-bedroom garden residence below, the property offers a highly flexible live-plus-income lifestyle rarely found in Brooklyn brownstone living. Equally compelling, the layout can be easily utilized as a single-family residence, allowing owners to enjoy the full scale and grandeur of this remarkable home while preserving future flexibility. Originally constructed in 1872 as the rectory for the former St. Augustine’s Church, this one-of-a-kind residence spans approximately 4,400 square feet on a generous 23' x 97' lot with a 23' x 47' building footprint, providing exceptional versatility for owner-occupants, multigenerational living, guest accommodations, or supplemental income opportunities. The current layout balances privacy, scale, and versatility in a manner rarely available within a historic Brooklyn townhouse. The expansive owner's triplex provides grand living and entertaining spaces, while the separate garden residence offers flexibility for extended family, guests, home office use, or supplemental income. For purchasers seeking a traditional townhouse experience, the residence can also be seamlessly enjoyed as a grand single-family home, offering approximately 4,400 square feet of living space across multiple levels with exceptional room proportions, abundant natural light, and beautifully restored architectural details throughout.
