A Private Pricing Opinion — what your apartment at 632–634 11th Street would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
632–634 11th Street combines two prewar buildings into an 18-residence condominium less than a block from Prospect Park. The barrel-front façades place it within the brownstone-scaled streetscape of the Park Slope Historic District. Apartments transfer as individually deeded condominiums within the two-building association.
Architecture and unit composition
LPC identifies George F. Roosen as the architect of No. 632, built in 1903 for William H. Johnson. The paired buildings have curved bays flanking their central entrances, stone-faced first floors and brick upper stories. Their projecting bracketed cornices and the pediment above No. 632's entrance carry neoclassical details. Both four-story buildings are walk-ups. Homes range from smaller one-bedroom apartments to two-bedroom layouts and larger combined configurations. Recorded sizes extend from roughly 490 square feet to more than 1,200 square feet. Some two-bedroom plans place the bedrooms apart, with living and dining space between them.
High ceilings, hardwood floors and large windows recur in the apartments. Fireplaces and in-unit laundry appear in selected homes. Rear-facing bedrooms look toward the interior courtyard, while the curved street-facing bays create a different room shape at the front. Private gardens and roof access belong to particular apartments.
Building operations
The two addresses share one condominium association and one billing tax lot, with 18 separate residential lots. The property is professionally managed and has resident storage. Heat and water are included in common charges — confirm the current allocation with the managing agent.
Historic-district designation covers both buildings. The residential lots are taxed in Class 2 without a building-wide abatement. The existing floor area exceeds the 2.0 residential FAR benchmark for the R6B zoning district.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
