A Private Pricing Opinion — what your apartment at 340 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.
340 11th Street combines elevator access with apartments arranged across several internal levels. The twelve-residence condominium includes upper triplexes and four-level layouts, with private roof terraces above. Built in 1991, it predates much of the newer condominium development in southern Park Slope. The building also offers separately deeded parking in an on-site gated lot.
Architecture and unit composition
Upper triplexes generally place the kitchen, living and dining areas on the entry level, with bedrooms on the floors above. Top rooms open to private roof terraces. Broad windows and southern exposures occur in these layouts, and some terraces look toward New York Harbor and the Manhattan skyline.
Apartment areas vary considerably. The resale inventory includes homes around 1,200 to 1,280 square feet and larger multilevel residences approaching 1,700 to 1,800 square feet. Interior stairs divide that area among living, sleeping and additional rooms, so usable space on each level is a significant part of the floor plan.
Bathroom counts differ among the layouts, with some three-bedroom configurations sharing one full bath and a powder room. In-unit laundry or washer/dryer connections appear in several homes. The building elevator reaches the apartment entrance; internal stairs remain part of daily circulation within the triplexes and four-level residences.
Building operations
Bicycle storage supplements the elevator and parking facilities. Deeded parking has been sold together with some apartments, but a residential purchase does not automatically include a space. Parking ownership and any separate carrying charges need to be included in the terms of that particular purchase.
The tax roll separates twelve residential lots from seven Class 4 lots. Residential ownership is dispersed, with the largest owner holding one apartment. There is no current building tax abatement; personal exemptions are owner-specific and don't indicate the tax treatment a new buyer would receive.

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.
