The Arches at Cobble Hill (401 Hicks Street)

The condominium reads as two connected buildings on one corner parcel. The church-and-rectory portion, roughly 39,500 square feet, holds 24 apartments; the academy building with its rear extension, roughly 45,195 square feet, holds 35. Both retain their original masonry and their institutional fenestration; the extension is where the plan's newer floor plates and the more regular layouts sit.

Apartments were delivered with plumbing fixtures and kitchen cabinetry, range, refrigerator, dishwasher and electric hood, pre-wiring for telephone, cable and internet, hard-wired smoke detection, and a washer/dryer closet or utility room in every unit. Bathrooms run to water closet and lavatory — some with double basins — and most with a bathtub. Cooling is served from three air-cooled chillers with a combined 180 tons of capacity; heating and domestic hot water run off six gas-fired boilers, with a handicapped lift in addition to the two main elevator machines noted in the energy budget.

Outdoor space is the differentiating asset and it is unit-specific. Front yards, rear yards, terraces, balconies and private courtyards are limited common elements appurtenant to particular apartments, and their maintenance falls to the unit owner. Two apartments in this building are rarely the same asset; comparables have to match on layout type, level count and outdoor allocation, not just bedroom count.

The Arches runs a boutique service model: a resident superintendent, a porter, three passenger elevators in 24-hour service, and a video intercom system at each unit rather than an attended desk. The board of managers purchased the basement superintendent's unit at conversion under a five-year purchase-money note at 8 percent, an item the plan disclosed as a future refinancing or assessment risk to unit owners; four decades of Cobble Hill co-op and condo experience says this is the sort of legacy obligation that resolves quietly but should still be traced through the association's current balance sheet.

Because heating gas, cooking gas, common electricity, water and sewer, and the cooling plant's electricity all run as common expenses, common charges at The Arches carry more of the building's energy cost than they do in a submetered building. Individual apartment electricity is separately metered and billed. The board's house rules have been amended over time — a bed-bug reporting protocol was added, with inspection costs split between the association and the affected unit owner — and current rules, fee schedules and assessment history should be requested in writing. Management history and current agent details are maintained in The Roebling Research Library and confirmed with clients during diligence.

Purchaser review: No board approval of purchasers or tenants; the board holds a right of first refusal on any sale or lease. Closing timelines of 30 to 45 days are typical.

Pets: Dogs, cats and household pets permitted, with a maximum of one dog and two pets total per unit. Anything else requires written board or managing-agent consent, revocable at the board's discretion. Pets must be carried or leashed in common portions.

Alterations: Board written consent is required for structural alterations, for air-conditioning or ventilator installation, for plantings on terraces and roofs, and for any exterior lighting or landscaping change. Exterior work additionally requires Landmarks approval.

Noise: Construction and repair work is limited to weekdays, 8:00 a.m. to 5:00 p.m., absent an emergency; amplified sound and instrument practice are restricted at night. The 80 percent floor-covering rule is enforceable by the board.

Roof and barbecuing: No personal or recreational use of the roof; no barbecuing outside board-designated areas.

Laundry and parking: No common laundry room and no on-site parking. In-unit washer/dryer connections throughout.

Flip tax: None disclosed in the plan; confirm current board fees, move deposits and assessments at offer stage.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $1,258/sf (recorded) across 6 sales. Median listing discount 2.1% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-00300-7501; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

Pull the current tax bill. The plan's J-51 projections are 2003 documents. Underwrite the unit's actual current assessment and run True Monthly Carrying Cost against it before you set a price.

Match the comparable to the layout. Duplex versus simplex, level count, and the size and type of the limited common element outdoor space drive value more than bedroom count does.

Check the vertical access on the specific unit. Three elevators serve the complex, but several top-floor rectory apartments are reached only by stair from the floor below. Confirm which you are buying.

Model the common charge honestly. Heating gas, cooking gas, common electricity, water and the central cooling plant are common expenses here. A per-square-foot common charge comparison against a submetered building is not apples to apples.

No parking, no laundry room. Both were disclosed at conversion and neither has an on-site fix. Every apartment has its own washer/dryer connection, which is the compensating fact worth stating.

Lead with the format. A family-scale duplex with private outdoor space and elevator access, inside the Cobble Hill Historic District, is a listing sentence with almost no competition in the neighborhood.

Stage the outdoor space as a room. Courtyards, terraces and yards are the assets that separate this building from the district's row-house floor-throughs. Photograph them furnished and in season.

Explain the conversion. The retained masonry shell, the inserted floors and the Scarano design — including the project's 2004 SARA design award — give the building a provenance line that generic 2000s infill cannot match.

Be precise about carrying costs. Buyers who understand that heating and cooling sit inside the common charge underwrite the number correctly. Buyers who do not will re-trade at diligence.

Anchor to in-building comparables. Same layout type, same outdoor allocation, from 2025 forward. Neighborhood-average per-square-foot figures will misprice this building in both directions.
