A Private Pricing Opinion — what your apartment at 64 West 15th Street 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.
64 West 15th Street places a twelve-home loft cooperative at the corner of Sixth Avenue. The typical floor is divided into east and west residences, with direct elevator entry. The eastern layouts are generally around 1,400 square feet; the western layouts are larger, commonly about 2,000 to 2,200 square feet.
That division is the starting point for understanding the building. Large open living rooms, tall ceilings and the positions of exterior windows reflect its loft form, while individual renovations have introduced different bedroom counts and internal rooms. The ground-floor inventory also includes duplex space with a mezzanine.
Architecture and unit composition
The six-story masonry structure has a corner footprint with frontage along both West 15th Street and Sixth Avenue. Two residences per typical floor keep the interior subdivision relatively simple. Elevator landings lead into the apartments, and the east and west lines have materially different floor areas.
Some layouts retain broad open living and dining areas; others divide that volume into enclosed bedrooms and workspaces. Lower-level duplex configurations can add internal stairs and mezzanine space. Their circulation is different from that of the single-level lofts above.
The recorded areas are not uniform even within the smaller line: ground-floor homes can depart from the typical upper-floor footprint. Bedroom count alone is consequently a poor description of the amount or arrangement of space here.
Building operations
The cooperative provides basement storage and a video intercom. Elevator access is central to the upper-floor residences, with private entry into the lofts. Individual homes have been fitted with washer/dryers, and the installations vary with the renovation.
The corporation is responsible for the building's shared real estate tax and common structure. The lot has no building-wide tax abatement. It is outside a designated historic district, despite its prewar loft character and proximity to landmarked blocks farther south.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00816-0078) 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.
