A Private Pricing Opinion — what your apartment at The Cobble Hill House 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.
Cobble Hill has hardly any new-construction condominium inventory at brownstone scale. Buyers who want an elevator, parking and a new building in the neighborhood usually end up weighing the high-rise River Park towers on the former hospital campus to the north. The Cobble Hill House is the low-rise alternative: 27 apartments in a five-story, 50-foot masonry building on a residential side street, with 29 deeded parking spaces for 27 apartments.
The site ties it to the same history as River Park. Lots 7, 8 and 9 (74–78 Amity Street) were Long Island College Hospital property. In 2001 DOB filings described 76 Amity as hospital administrative offices. The lots moved from the hospital to the State University's Downstate holding company in 2011. In September 2015 they went to an affiliate of the campus buyer as part of the closing of the LICH sale, and that affiliate conveyed them to the sponsor, Vega 12, within the same month, per ACRIS. The offering plan discloses that the property is subject to a declaration of covenants and restrictions recorded in connection with the LICH campus disposition. Buyers' counsel should read it.
The building went up as-of-right under the neighborhood's existing zoning. It stays within the LH-1 height limit, which is why it sits at townhouse scale while the River Park towers across Amity Street are taller.
Architecture and unit composition
The building has a cellar, four above-grade floors and a penthouse floor. Per the offering plan, the ground floor holds the community-facility unit, four residential units, the indoor recreation area, the bicycle room and support space. The 29-space parking area is also at this level. The roof holds eight cabana units, the five private penthouse terraces and the elevator machine room.
Residential units run from 1A through PHE. The first floor has four residences plus the community-facility unit (1E), floors 2 through 4 have six units each, and the penthouse floor has five. Layouts range from one to three bedrooms, per marketing records.
City data note. Aggregate sources sometimes list this address as 47 units, 65 units or a single unit. The correct residential count is 27. The other lots are parking spaces, cabanas and one community-facility unit, none of them apartments.
Building operations
The Cobble Hill House is a small, professionally managed condominium with a superintendent. The residential units and the parking area share one elevator. The offering plan warns that residents must use the stairs if it is out of service.
Sponsor position. The sponsor sold all 27 residential units to separate buyers between April 2019 and November 2021, and sold the community-facility unit in July 2022, per ACRIS. The 2027 Department of Finance roll shows no unit still owned by the sponsor, and every unit lot is classed as a residential condominium, parking, cabana or commercial unit. None carries the city's condominium-rental class, so there is no rental block inside the condominium.
Finances. Per the audited financial statements on file for 2020–2021, the association had no debt. It had a modest cash position, under $100,000 including a working-capital fund of about $43,000. That fund is built from each buyer's one-time contribution of two months' common charges at closing, and it had not yet been supplemented by a funded reserve study. The same statements show common-charge arrears on sponsor-associated units at year-end 2021, before the sponsor's final sales. They also disclose a January 2022 water event from a frozen sprinkler pipe that damaged several units and common areas, with the insurance recovery not yet determined when the statements were issued. Buyers should confirm the current reserve balance, that the sponsor arrears were collected, and how the 2022 claim was resolved.
Community-facility unit. Under the plan, the ground-floor community-facility unit may be used as a professional office or for other permitted community uses. Its owner can sell or lease it without the board's right of first refusal and does not get to appoint a member of the board of managers. Ask what the unit is currently used for.

The Cobble Hill House trades as boutique new construction in a neighborhood of row houses and older conversions, and it prices on a per-square-foot basis. Penthouses with private roof terraces lead the building. Upper-floor units with terraces come next, then interior-line units. Deeded parking and roof cabanas are priced separately and add real value in Cobble Hill, where off-street parking is scarce. Resale activity since the 2019–2021 sponsor closings has been steady and spread across floors.
Model current taxes, common charges, assessments and financing together. The 2020–2021 audited statements reported no association debt at that time; obtain current financials and tax bills before comparing total carry with abated new development elsewhere in Brooklyn. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Market read. Most recent trades (2026 to date) cleared a median $1,800/sf (floor-adjusted) across 2 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 0.2% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
There is no abatement to lose. The current tax bill is the real one, so underwrite to it.
Ask about reserves. The reserve cushion looked thin in 2021, when the 27-unit building was a few years old; that reading is dated and does not predict assessments. Get the current balance and any capital plan.
Close out the 2022 water claim. Confirm that the sprinkler-pipe repairs are finished and that any insurance deductible or assessment has been settled.
Buy the parking space with the apartment if you can. Spaces are separate deeds, and the supply is fixed at 29.
Read the LICH covenants. The plan discloses a declaration of covenants and restrictions tied to the campus sale. Have counsel summarize what it restricts and whether it binds unit owners.
What to know if you’re selling
Lead with scale and parking. A new elevator condominium at townhouse height with deeded parking, on a Cobble Hill side street, has almost no direct competition.
Say what the building is. It is ground-up construction, not a hospital conversion. Buyers who have read about River Park may assume otherwise.
Transfer the extras cleanly. If the sale includes a parking or cabana unit, have separate deeds and common-charge figures ready for each.
Expect a condominium closing timeline. There is no board approval, only a right-of-first-refusal waiver.

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.
