A Private Pricing Opinion — what your apartment at 280 West End Avenue 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.
280 West End Avenue occupies a conspicuous corner mansion designed by Charles T. Mott for developer William J. Merritt. Built in 1887–89, the house combines rounded projecting bays, brick above a sandstone base and a gabled roof punctuated by dormers. The long West 73rd Street frontage gives apartments access to a second street exposure within a building originally designed as a single residence.
Architecture and unit composition
The Romanesque Revival exterior includes iron balconette railings and arched leaded-glass windows in the eastern extension. Its roofline and corner bays are prominent elements of the landmarked structure.
The later apartment conversion divided the house into homes with different relationships to those original features. One-bedroom layouts can include a separate dining area, while rooms within the curved bays have windows following the rounded exterior. Ceilings above ten feet and surviving woodwork appear in selected interiors.
The corner location gives the building two street-facing elevations, but exposure varies with apartment position. A room facing West End Avenue has a different outlook from one along West 73rd Street or toward the rear of the lot. The original house's roof and extensions also make the upper and lower floor plates different from each other.
Building operations
The cooperative conversion sponsored by Saul Associates was accepted in May 1986 and became effective in August 1987. The filing offered ten apartments. Ownership is through 280 West End Owners Inc.
Common laundry and basement storage serve the converted house. Building improvements reported in 2025 included roofing work, a video intercom and updated electrical service to individual apartments. These improvements relate to an older structure whose exterior remains subject to historic-district oversight.
The R10A zoning allowance is substantially greater than the existing built floor area. Landmark designation adds another layer of control over exterior changes and any proposed enlargement; unused zoning floor area alone isn't an approved expansion.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01165-0001) 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; square footage on co-ops is not officially recorded, figures shown are approximate.

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.
