300 West 83rd Street is a Gaetan Ajello corner cooperative at West End Avenue, built in 1923 in the years when Ajello was shaping so much of the Upper West Side that the era's press described him as the architect who defined the avenue. The building holds down the corner of 83rd Street and West End — a quiet, tree-lined block a short walk from Riverside Park to the west and Broadway's shopping and the 79th and 86th Street subways to the east.

Its strength is the apartment stock. The building was conceived for established families and is built almost entirely of Classic Six and Classic Seven layouts — the gracious entry-gallery, separate-dining, maid's-room plans that buyers searching prewar West End specifically want. Converted to a cooperative in 1980, it has been owner-occupied for more than four decades and offers a livable, full-service version of prewar West End Avenue: real amenities, real space, and a river-view roof deck on top.

Architecture and unit composition

Ajello worked in a confident Italian Renaissance idiom — masonry over a classical base, proportioned fenestration, and ornament held in reserve so the building reads as solid rather than showy. The fifteen-story corner massing gives the building light on multiple exposures, and the upper floors capture the open western light and Hudson glimpses that make West End's tall corners desirable.

Inside, the homes are the prewar standard the avenue was built for: high ceilings, hardwood floors, entry galleries, separate dining, and the generous room counts of the Classic Six and Seven. With only 48 apartments across fifteen stories, the floor plates are roomy and the building stays intimate — a scale that supports an attentive staff and a stable, owner-occupant base.

Building operations

300 West 83rd is a full-service cooperative: a 24-hour attended lobby, a live-in superintendent, central laundry, private storage, and a bike room, capped by a fully landscaped roof deck with Hudson River views — the building's signature shared amenity. The cooperative is pet-friendly. A 2% flip tax is paid at closing, and financing follows the standard prewar West End posture, with a conservative down-payment requirement that keeps the building well-capitalized and resident-committed. Subletting is permitted under board policy after an initial owner-occupancy period.

Full closing history with price-per-square-foot over time, the complete retrade record, and every line that has traded.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01245-0025) 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.

What to know if you’re buying

This is a board-approval cooperative. Plan for the building's conservative financing posture and underwrite to strong post-closing liquidity; the package and interview are taken seriously here. Budget the 2% flip tax into your closing math, and confirm your intended use against the building's owner-occupancy orientation — this is a residence-first house, not an investor building. The reward is a Classic Six or Seven on a quiet West End corner, with a river-view roof deck and full staffing, at the relative value prewar side streets offer against the avenue's marquee addresses.

What to know if you’re selling

The marketing case is the apartment and the amenity: a graceful prewar Classic Six or Seven, an Ajello corner building, and a landscaped roof deck with Hudson views. Inventory is thin, so a well-prepared listing draws a focused, qualified pool — preparation, light staging, and accurate pricing against the live comparable set are what convert that interest into an accepted offer. Price to recent prewar West End closings of comparable size and condition, and let the river-view roof deck and full-service operation support the number. The Roebling Team prepares the board-package narrative in parallel with the listing so an accepted offer clears review cleanly.
