114 East 84th Street

Park 84 is a nine-story pre-war masonry building of the kind that defined the Upper East Side cross streets before the First World War — solid construction, classical detailing, and the gracious proportions of early-1900s planning. The lobby has been renovated to a contemporary standard while the apartments retain pre-war character: good ceiling heights, hardwood floors, and well-laid-out rooms.

With 34 apartments across nine floors, the building offers a range of pre-war layouts from efficient homes to larger family residences, and the permission for in-unit washer/dryers makes renovation and modernization straightforward — a meaningful advantage over co-ops that bar them. The mid-rise scale keeps the shareholder community small and the building's operation personal.

Park 84 runs as a full-service cooperative. A 24-hour doorman and a live-in resident manager anchor the staffing, and the amenity set is deep for the building's size: a fitness room, a roof deck, a bicycle room, private storage, and a central laundry room.

The board's policies are buyer-friendly for Carnegie Hill. The cooperative permits financing of up to 75% of the purchase price, well above the neighborhood norm, and the building welcomes co-purchasing, gifting, and parents buying for children — flexibility that opens it to a broad range of buyers. Pets are permitted, and in-unit washer/dryers are allowed. A 2% flip tax is paid by the purchaser, and pieds-à-terre are not permitted — this is an owner-occupied building. Prospective purchasers should expect a board package and interview.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01512-0062) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price.

Park 84 is among the more accessible full-service cooperatives in Carnegie Hill. Financing up to 75% is permitted, dramatically lowering the cash hurdle, and the board's openness to co-purchasing, gifting, and parents buying for children widens the path to approval. Pets and in-unit washer/dryers are allowed — the latter a real advantage for buyers planning renovations. Budget for the 2% flip tax, which the buyer pays, and note that pieds-à-terre are not permitted, so this is a primary-residence building. Expect a standard board package and interview; a financially sound applicant should find the process manageable.

Lead with services and accessibility. A 24-hour doorman, roof deck, and gym on a Park-adjacent block — combined with 75% financing and family-friendly purchasing policies — reach a far broader buyer pool than a charm-only Carnegie Hill co-op. Emphasize the in-unit washer/dryer allowance, which sets the building apart from older neighbors. Benchmark to full-service Carnegie Hill cooperatives, not the white-glove park-front tier, and price to the building's accessible, amenity-rich position. Present a board-ready, owner-occupant buyer — given the pied-à-terre prohibition — to ensure a clean closing.
