345 Clinton Avenue is the working center of the Clinton Hill Co-ops and the address where the complex meets the historic district. The building holds the boiler plant that heats the entire South Campus, the cooperative's on-site management office, and the Lafayette Avenue frontage where the original renting office sat. It is also, unlike its North Campus counterparts, a landmarked building — the Landmarks Preservation Commission designated the Clinton Hill Historic District on November 10, 1981, and drew the line so that 325, 345, 355, 361 and 365 Clinton Avenue fell inside it while the wartime blocks north of Willoughby Avenue did not.
That boundary decision is worth understanding, because the designation report is candid about how the Commission viewed these buildings. Clinton Avenue became Brooklyn's Gold Coast after Charles Pratt built at 252 Clinton in 1874 and his business associates followed; the mansions of John Arbuckle, A.G. Jennings and Dr. C.N. Hoagland went up around them, and Pratt's sons received houses along the same blocks. The report describes the arrival of the 1940s high-rise housing as a blow to the avenue's character. Designation nonetheless swept the South Campus in, and the practical consequence for an owner today is straightforward: exterior work at 345 Clinton Avenue, windows included, passes through Landmarks review exactly as it does at the row houses across the street.
The buildings themselves are Harrison, Fouilhoux & Abramovitz — Wallace K. Harrison's office, five years before the United Nations Secretariat. The design intelligence sits in the plan rather than the elevation. Each building is a modified rectangle whose long faces push outward roughly seven feet several times along their length, and the result is that nearly every apartment in the complex occupies a corner and gets cross ventilation. The exteriors are face brick with painted steel casements on slate sills; the entrances carry white marble jambs and a blue-and-white ceramic tile mosaic in a nautical design, a small dedication to the Navy Yard families the project was built for.
The South Campus site does something the North Campus site does not. Clinton Avenue here sits eight to nine feet above the interior courtyard and Waverly Avenue, so the four buildings on Block 1944 step down into a landscaped court reached by stairs from the avenue, with the tenant parking lot filling the Greene Avenue end of the block. It is the closest thing in Clinton Hill to a garden apartment setting at scale.
For buyers, the appeal is a landmarked address on the mansion row with the operating economics of a 1,200-apartment cooperative behind it. For sellers, the historic district and the Harrison attribution are the two lines that distinguish this address from the rest of the complex.
Architecture and unit composition
The South Campus occupies Block 1944 between Clinton, Waverly, Lafayette and Greene Avenues, with a fifth building at 325 Clinton Avenue on the block to the north, over the Lafayette Avenue subway entrance. The Department of Finance records 424 apartments on the tax lot addressed 345 Clinton Avenue; the offering plan's site plan shows the South Campus buildings running 96 to 112 apartments each across 12 to 14 stories.
Floor-to-floor heights run approximately 8 feet 10 inches. Each floor is served by two elevators and a scissor-stair pair off a central corridor, with the compactor chute in a small ventilated room between the elevators. Apartments were delivered with wood parquet floors, plaster walls and ceilings, wood pantry, wall and base cabinets, gas ranges and tiled bathrooms; first-floor lobbies and corridors are terrazzo with stenciled plaster. The share schedule for the South Campus buildings concentrates in 2½-, 3½- and 4½-room apartments, with larger lines dispersed through the upper floors.
Because the plans repeat across twelve buildings, the differentiators inside the inventory are floor, exposure — courtyard and Waverly Avenue versus Clinton Avenue — line, and renovation state. There is no in-unit laundry anywhere in the complex; washing machines and dryers are prohibited in apartments and the laundry rooms are the substitute.
Building operations
345 Clinton Avenue is the plant building for its section. Four Kewanee boilers built in 1946, converted from coal to oil, sit in the cellar and supply steam heat and domestic hot-water heating to all of the South Campus buildings through underground mains, with domestic water pumped to a 20,000-gallon Rosenwach wood tank above each building's elevator machine room. Heating controls for every South Campus building live in this boiler room, zoned building by building through outdoor-air and condensate sensors. Owning in the plant building means the mechanical room, its noise profile and its service traffic are part of the address — and it also means the cooperative's most consequential capital assets sit under your feet.
The capital history is documented in the plan. A GMAC first mortgage closing March 31, 1997 carried a $4,336,600 repair escrow for asbestos abatement, paving, repointing and masonry, boiler repairs, roof work, elevator renovation and replacement, Local Law 10 work and electrical wiring and metering, together with a monthly replacement-reserve deposit; the audited statements for the year ending March 31, 1999 record that mortgage maturing April 1, 2027. Any 2026 buyer should ask management directly for the corporation's current debt position, maturity and refinancing plan.
Maintenance ran at approximately $8.417 per share per month as of February 1, 2020 per the plan's twenty-fourth amendment. The board seats seventeen directors, and the amendment states expressly that neither the sponsor, the co-sponsors nor other holders of unsold shares have ever controlled it. As of February 1, 2020 the sponsor group held 144 apartments, a co-sponsor group held 61, and the corporation itself owned 16; those units are rented, and the current figures should be requested at contract because lenders weigh them. Management history and current agent details are maintained in The Roebling Research Library and confirmed with clients during diligence.

What to know if you’re buying
You are inside the historic district here. Designated November 10, 1981, the Clinton Hill Historic District takes in the South Campus. Window replacement and any exterior alteration go through Landmarks, and that is a scheduling and budget fact worth knowing before you plan work.
This building carries the South Campus plant. Four 1946 boilers and the section's heating controls are in the cellar. Ask about the plant's condition, recent work and the capital plan.
The rulebook is restrictive by design. Two-thirds shareholder consent for sublets absent a board resolution, no washers or dryers, and a smoke-free apartment if you buy today.
Ask about the mortgage. The 1997 first mortgage was recorded as maturing April 1, 2027. Get the corporation's current debt and refinancing plan, then run True Monthly Carrying Cost analysis against the apartment's maintenance and any assessment.
The G train is around the corner. Clinton–Washington Avenues on Lafayette Avenue is a block away, with the C at Lafayette Avenue and Fulton Street a short walk south.
What to know if you’re selling
Lead with the district. A landmarked apartment on the Clinton Avenue mansion row is a sentence most large Brooklyn co-op listings cannot write. Pair it with the Harrison, Fouilhoux & Abramovitz attribution.
Show the plan, not just the rooms. The stepped elevation that puts nearly every apartment on a corner with cross ventilation is a design argument a buyer can verify standing in the apartment.
Stage the courtyard side. The eight-to-nine-foot grade drop from Clinton Avenue into the landscaped court is the South Campus's best feature and the hardest one to convey in a floor plan.
Price per room against the complex and its peers. The right comparables are the other Clinton Hill Co-ops buildings and the large Clinton Hill and Fort Greene cooperatives, adjusted for the historic district position.
Disclose the plant and the house rules up front. Both come out in diligence; leading with them protects the deal.
