315 West End Avenue

The building reads as a product of its moment: 1948 yellow brick, restrained ornament, and the signature corner casements that were a late-Deco and early-modern flourish on the avenue. Where the pre-war buildings a few doors down lean on limestone bases and elaborate cornices, 315 makes its case through proportion and glazing — the corner windows give the better-positioned lines a bright, dual-exposure quality that is hard to replicate in newer construction.

Inside, the 24 residences run to gracious post-war layouts — sensible room counts, hardwood floors, and the solid plaster-and-masonry construction of the era. Several lines combine across the building's width, and the corner apartments are the most sought-after for their light. Ceilings and proportions are post-war rather than soaring pre-war, but the homes are quiet, square, and efficient — the kind of stock that renovates well and lives larger than its footprint suggests.

315 West End Avenue is staffed by a live-in resident manager and superintendent, with an elevator, video-intercom entry, a central laundry, a bicycle room, and basement storage offered to shareholders at no charge — an unusual and genuinely valuable perk in a market where storage typically commands a monthly fee. The building is pet-friendly, a meaningful draw on the family-heavy stretch of West End in the 70s.

As a 24-unit cooperative, the building runs lean: common charges support the staff, the systems, and the reserve rather than a deep amenity package. Review the actual budget, debt, reserves and assessments before judging costs; a modest amenity program alone does not establish disciplined spending.

Market read. Most recent trades (2025) cleared a median $1,544/sf (floor-adjusted) across 2 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 0.4% 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 1-01184-0083). 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.

This is a traditional cooperative, so purchases clear a board package and interview. The building is pet-friendly, and storage and bike-room space are provided at no additional charge. Pieds-à-terre are permitted and subletting is permitted with conditions; confirm the building's current financing, liquidity and occupancy requirements and the sublet terms from its governing documents and application instructions.

Position matters more than usual here: the corner casement lines carry the building's best light and command the strongest pricing. Buyers should weigh exposure and floor carefully, and budget for the cosmetic updates that post-war kitchens and baths often invite.

The selling story is location, light, and low carrying costs. A corner co-op two blocks from Riverside Park, with no-charge storage and a pet-friendly board, offers location and building features to compare with larger amenity buildings. Lead with the corner exposures and the disciplined monthly costs; both are durable differentiators in this corridor.

Because the building is small, a single well-presented listing can define the comp set for the year. Pricing should be benchmarked to recent West End Avenue co-op trades in the 70s rather than to amenity-heavy buildings, and a buyer with clean, complete financials is better positioned for board review — worth screening for early.
