Description

7 St. Marks Avenue — A One-of-a-Kind Park Slope Historic District Residence 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. 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, offering expansive interiors complemented by meaningful outdoor space and future potential. Currently configured as a gracious owner’s triplex above a beautifully appointed two-bedroom garden residence, the layout offers remarkable flexibility for a primary residence, multigenerational living, income-producing use, or conversion into an expansive single-family home. The balance of privacy, scale, and connectivity creates an ideal environment for both modern living and long-term adaptability. Meticulously gut-renovated and thoughtfully restored to honor its original Gothic Revival style and architectural character, the home features 7 bedrooms, 5.5 baths, and a dedicated home office, seamlessly blending historic craftsmanship with sophisticated contemporary upgrades. Original details reflective of the home’s rich heritage include Gothic pointed-arch windows, three working marble fireplaces, a dramatic entryway, and a beautifully restored walnut staircase that anchors the residence with warmth and craftsmanship. The home’s restored Italianate cornice, accented with Gothic arch detailing, and the classic heavy Italianate stoop further enhance its commanding architectural presence and reflect the distinctive design language of the period. The thoughtfully designed kitchen combines functionality with refined design, featuring custom cabinetry, a built-in pantry, desk area, and premium stainless-steel appliances, including a Sub-Zero refrigerator and Miele induction oven. Just beyond, a terrace descends seamlessly to a spacious private garden, creating an effortless indoor-outdoor flow ideal for entertaining, dining, or quiet retreat. Throughout the home, hidden custom storage integrated within the walls maximizes utility while preserving a clean, tailored aesthetic. A full basement with high ceilings provides exceptional added space for recreation, storage, fitness, studio use, or future customization. Modern infrastructure has been comprehensively upgraded with all-new mechanical systems, including an advanced heat pump system providing centralized heating and cooling throughout the home. Unlike traditional natural gas boiler systems that generate heat through combustion, heat pumps use electricity to transfer existing heat from the air, delivering a cleaner, quieter, and significantly more energy-efficient approach to year-round climate control. The top level features a wet bar opening directly onto a private roof deck with sweeping Brooklyn and Manhattan skyline views — extraordinary for entertaining or enjoying quiet moments above the city. Perfectly positioned on a picturesque tree-lined block at the gateway to St. Marks Avenue, the residence is moments from Prospect Park, Barclays Center, and the vibrant dining, shopping, and cultural corridors of Fifth and Seventh Avenues. The Bergen Street station (2/3 trains) is nearby, while Atlantic Terminal provides exceptional access to the 2/3/4/5/B/C/D/N/Q/R subway lines and the Long Island Railroad. Previously highlighted by Brownstoner as “House of the Day” and most recently featured in the 2026 Park Slope Sustainability Tour, 7 St. Marks Avenue represents a truly exceptional opportunity to own one of Park Slope’s most architecturally distinctive and historically significant residences.
