About the building
Morris Adjmi designed 16 West 21st Street as a narrow fourteen-story condominium within the Ladies' Mile Historic District. Frosted glass panels articulate the façade in a grid of columns and horizontal bands, responding to the proportions of the district's commercial architecture. F&T Group developed the building, with interiors associated with Zac Posen.
The nine residences include full-floor two-bedroom homes, larger duplexes and a triplex penthouse with terraces. Single-floor homes are approximately 1,368 square feet, while duplex layouts extend across twice that area. Keyed elevator access serves the residential floors, including both levels of some duplexes. Selected homes have private outdoor space, and residents also share a roof deck and fitness room.

What to know if you’re buying
Nine residences support a staffed, fourteen-story building. Elevator service, façade work and shared fitness facilities create operating obligations across a very small residential association. For a duplex, access from both levels also affects how the home works if one entrance is unavailable during elevator maintenance.

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.
