A Private Pricing Opinion — what your apartment at 9 West 20th 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.
9 West 20th Street places one condominium residence on each of its eleven upper floors. The former mercantile building retains the deep, narrow footprint of its commercial origins, with approximately 2,150 square feet in the typical loft. Keyed elevator entry leads directly into each home, and retail occupies the ground floor.
William G. Pigueron designed the twelve-story store-and-loft building for Acme Building Company in 1907–08, according to LPC. It replaced a four-story rowhouse. It was later converted into apartments under a condominium offering accepted in June 2001. DOB's conversion work, signed off in May 2002, created one Class A apartment on each floor from the second through the twelfth.
Architecture and unit composition
The original structure is 26½ feet wide, with a red-brick and stone façade and copper-clad projecting windows. It extends almost the full depth of its lot. Its floor-through apartments combine large living and dining areas with bedrooms toward the other end. Many have two principal bedrooms and an additional den or office within approximately the same overall footprint.
Ceiling heights differ by floor, with the lower residential level reaching nearly twelve feet and other lofts closer to ten and a half feet. Exposed beams and oversized windows recur in the interiors. Central air conditioning and dedicated laundry areas are present in completed apartment renovations.
The relatively consistent floor area makes layout efficiency especially relevant. A den within the middle of a deep loft does not have the same window exposure as a room on the street or rear façade. Bedroom descriptions should follow the approved layout and actual light and ventilation.
Building operations
The building has a superintendent, basement storage and bicycle storage. Direct elevator access is part of the full-floor arrangement, with the eleven residences sharing the lift and common building systems. A commercial tax lot remains separate from the residential units.
The Ladies' Mile designation applies to the exterior, including the street façade and its window pattern. Alterations to those elements require the applicable preservation approvals. The loft interiors have changed independently, so the condition of their heating, cooling and laundry installations varies across homes.

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.
