A Private Pricing Opinion — what your apartment at 9 West 16th 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 16th Street preserves a mansion-sized Greek Revival house from the residential neighborhood that grew around Union Square in the mid-nineteenth century. Built for merchant Robert Kelly in 1846, it has a broad brick façade and an unusual curved bay rising through the principal stories.
LPC records a physician's office introduced in 1928, apartments created on the upper floors in 1956, and the removal of the medical office in 1961. The property has been entirely residential since that final conversion.
Architecture and unit composition
The roughly 33-foot width gives the building a larger frontage than a conventional narrow townhouse. Its bowed front is the defining feature: the curved wall changes the shape of the street-facing rooms and admits light at angles to the main façade. Brickwork and ironwork retain the scale of the original house.
The cooperative contains both expansive floor-through homes and smaller apartments. The larger layouts extend across the building's width; selected upper residences have private terraces. Ceiling heights and surviving period details vary with the original floor level and subsequent alteration work.
An elevator serves the building. The upper outdoor spaces are private to particular homes. They sit above the original bowed street façade, the principal historic element visible from the block.
Building operations
Individual landmark designation applies directly to this property. Exterior alterations, including work affecting the windows and roof, therefore carry a preservation review requirement. LPC considered a penthouse-modification application in 2018, illustrating that upper-level work falls within the building's landmark oversight.
The cooperative's broad frontage, elevator and historic exterior remain shared building components despite its small residential inventory. The floor-through and smaller homes occupy different amounts of the house, making the proprietary lease's allocation of maintenance and alteration responsibilities consequential for an owner considering combination work.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00818-0033) 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.
