284 Fifth Avenue (The Wilbraham)

The Jardines' design alternates thick rough-cut stone blocks with ornamented courses to build the corner piers, and the carved detail — knotted geometrics, medieval faces — rewards close viewing; the original drawings called for six stories, with the seventh floor and the mansard added by amendment during construction in 1889. Inside, the building's roughly three dozen apartments are predominantly studios and one-bedrooms shaped by the original two-room-suite plan: high ceilings, oversized windows on the Fifth Avenue and 30th Street exposures, and pre-war proportion in compact footprints. Combinations exist — including duplexed units on the upper floors — and the penthouse level, enlarged in the 1935 renovation, holds the building's largest residence. Renovation quality varies unit to unit, and the landmark designation means façade and window work runs through LPC review.

This is a boutique, lightly staffed cooperative: a live-in superintendent, an elevator-operator service documented in listing records rather than a full doorman line, central laundry, storage, and a bike room. Two commercial units occupy the retail base, continuing the building's original configuration of shops below flats. The operational record on file is candid: the 2020 audited statements showed an operating deficit, the board corrected with a 15 percent maintenance increase in 2021 and then held 2022 to 0.5 percent, reserves stood near $187,000, and the $2.8 million underlying mortgage at 4 percent was scheduled to mature in October 2025 — making the refinancing terms a live diligence question in the current rate environment. The offering-plan amendments, due-diligence memorandum, building questionnaire, and insurance certificates are on file in The Roebling Research Library.

Market read. $/sf is measured on the latest sales with reliable square footage (2024): a median $910/sf (floor-adjusted) across 1 sale. The building has traded as recently as 2026. Median listing discount 1.8% 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 1-00832-0039). 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 on co-ops is not officially recorded, figures shown are approximate.

You are buying a designated landmark. The 2004 individual designation protects the façade and mansard permanently — the guarantee of the building's character and a practical constraint: window replacement and any envelope work require LPC review. Budget approval timelines accordingly.

The documented policies are broad. Pied-à-terre use, co-purchasing, guarantors, and LLC/trust structures are documented in listing records, sublets run case-by-case through the board, and purchasers pay a one-month working-capital contribution; the 2022 memorandum reports no flip tax, a separate matter from that contribution. Confirm whether a later resale fee has been adopted. Confirm specifics, including any financing cap, with the managing agent.

Understand the sponsor position. As of the 2022 records on file, the sponsor held 15 of 36 units with 9 sublet. High sponsor concentration can affect some lenders' underwriting and shifts building dynamics; verify the current count and your lender's posture early.

Underwrite the financials, not the romance. The building corrected a deficit with a sharp 2021 maintenance increase, the 2020 statements reported modest reserves, and the underlying mortgage’s stated October 2025 maturity requires a current debt-status check. Maturity alone does not establish refinancing or its effect on maintenance. Have your attorney review the current statements — we hold the prior diligence file for comparison.

Service expectations should be calibrated. Elevator-operator service and a live-in super, not a 24-hour doorman and amenity floor. Compact monthly carry is the trade. Run the Co-op Board Qualification Calculator before offering.

Market the landmark, specifically. Jardine brothers, 1890, bachelor-flats history, the Gilman Collamore shopfront, the 2004 individual designation — this is the most documented small building in its blocks, and the NoMad buyer responds to provenance. Use the facts, not adjectives.

Position against NoMad's new-condo pricing. Compare matched NoMad condominium sales and their charges, rather than assuming a two-to-one price difference. Present the 1890 fabric and individual landmark designation alongside the co-op’s purchase terms — with a policy framework flexible enough for the pied-à-terre and investor-adjacent buyers the neighborhood attracts.

Disclose the financial arc with documents. Provide the 2021 maintenance history and current documents establishing whether the mortgage was refinanced, extended or repaid; explain any resulting charges without promising a transaction outcome. We provide the underlying file from the Research Library to serious buyers' counsel.
