A Private Pricing Opinion — what your apartment at 378 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.
378 West End Avenue is an Upper West Side development joining a prewar landmark-district building to a contemporary tower. Alchemy Properties acquired the site from the West End Collegiate Church in 2018 — the 1915 corner building, designed by Schwartz & Gross, had housed The Collegiate School until the school's 2018 relocation. Rather than demolish, the developer restored the historic structure and joined it to a new brick-clad tower designed by COOKFOX Architects, producing 58 condominium residences that launched for sale in 2021; the complete disposition and control history requires current plan amendments and ownership records.
The architectural argument is preservation as marketing. The historic building's terra-cotta cresting, zinc sundial, and balconies were repaired; the new tower uses hand-set brick, with its warm south elevation responding to the adjacent church's masonry. The result is a building that sits comfortably inside the West End–Collegiate Historic District Extension — where the 1915 structure is a contributing building under Landmarks Preservation Commission review — while delivering the floor plans, ceiling heights, and amenity program of new construction. For buyers who want new-development systems without the glass-box aesthetic, that combination is the entire point.
The apartment composition spans a broad range of bedroom counts. Layouts run from one-bedroom through six-bedroom configurations plus a penthouse collection, with no studios — this is a building of substantial homes, not a mid-market unit-count play. COOKFOX's biophilic design language (the firm is known for integrating daylight, planting, and a private garden into its projects) gave 378 a wellness-and-amenity story that landed well in the pandemic-era market into which it sold.
Architecture and unit composition
The 58 residences distribute across the restored 12-story historic building and the 18-story new tower. The historic corner structure carries a rusticated stone ground story, a two-story stone door surround with a swan's-neck pediment, polychrome terra-cotta ornament, and multiple cornices; the new portion uses hand-set brick and stepped massing. Interiors are new-construction throughout — high ceilings, large windows, and the redevelopment's mechanical systems, whose commissioning and current condition should be checked.
Apartment scale skews large: one-bedroom homes at the smaller end, up to six-bedroom layouts and a penthouse collection that includes a duplex/triplex of roughly 7,485 square feet with multiple outdoor spaces. The amenity program runs to roughly 11,000 square feet across the pool, spa, fitness and sports facilities, music studio, screening room, club lounge, library, children's playroom, and private garden.
Building operations
378 West End Avenue operates as a full-service condominium with 24-hour doorman and concierge, on-site parking, and the extensive amenity roster noted above — pool, spa, fitness center, squash and basketball courts, sports simulator, music recording studio, screening room, club lounge, library, children's playroom, and a private garden. The pet-washing room signals a building designed around resident daily life rather than a pure investment product. Common charges and property taxes reflect a new-construction full-service building; buyers should model the full monthly carry.

Common charges plus real estate taxes, combined into one monthly figure the way New York condominium listings show them. Add a mortgage payment for the monthly outlay. The split into common charges and taxes comes from the listings that also give the annual tax, a different sample, so the two lines need not add up exactly to the combined median; a tax abatement can hold taxes below the full amount until it expires. A summary of recorded sales and listings, not a current bill; charges change.

The latest available filing classified the facade as SWARMP — Safe With A Repair and Maintenance Program: the inspector (QEWI) identified conditions requiring monitoring or repair, with repairs due by the deadline stated in the filing. The scope, timeline, and how the building funds the work are building-specific — we review the filings and board materials for you.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2020–25 to 2025–30. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Recent sales
378 West End Avenue prices as ultra-luxury Upper West Side new development. The offered mix runs from one-bedrooms through penthouses, without studios. Confirm current sponsor inventory and count dated resales before judging the comparable set; apartment-specific factors remain relevant — exposure, floor, the historic-versus-new portion, and outdoor space all drive meaningful pricing variation. Per-square-foot remains the right metric for this condo; the strongest pricing anchors are the most recent closings on the specific line rather than building-wide averages.

Market read. Most recent trades (2026 to date) cleared a median $2,810/sf (floor-adjusted) across 1 sale. 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 0.0% from the last ask.

What to know if you’re buying
The preservation-plus-new-construction hybrid is the product. You get new-development systems, ceiling heights, and amenities inside a building that reads as prewar West End Avenue. Buyers who want a pure glass tower should look at the Riverside South condos; buyers who want pure prewar should look at the surrounding co-ops.
Compare the apartment configurations. No studios; layouts run one- through six-bedroom plus penthouses. This is a building of substantial homes.
The amenity program is deep. Roughly 11,000 square feet — pool, spa, sports facilities, music studio, screening room, children's playroom, and a private garden.
Pets are welcome. The building includes a dedicated pet-washing room.
Condominium flexibility applies. Pied-à-terre and investment use are permitted under the declaration; 30–45 day closings are typical. Confirm specific minimum down payment and sublet terms at offer stage.
Carrying cost is material. Model common charges, property taxes, utilities, and insurance together before committing.
What to know if you’re selling
The preservation story is part of the marketing. The restored 1915 landmark, the COOKFOX design, and the historic-district setting are differentiators against pure new construction.
Pricing requires apartment-level comparable analysis. With a thin resale set, position against the most recent closings on the specific line — not building averages.

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.
