Beekman Mansion

At 36 residences across 10 stories, Beekman Mansion is intimate by design — a low ratio of apartments to staff that translates into attentive service and a quiet building. The neo-Renaissance façade gives the address its dignity, while the maisonette duplexes at the base are a distinctive feature, offering townhouse-style living with the security and service of a full co-op. Above, the apartments are classic pre-war: gracious room counts, solid construction, and the proportions that buyers seek in this era of the East Side.

Because the building is small, layouts vary, and value is set by floor, light, river or garden orientation, and the quality of each home's most recent renovation. A penthouse or a high-floor home with open exposures toward the river commands a clear premium over a lower interior unit.

Beekman Mansion is a white-glove cooperative with a 24-hour doorman, a live-in superintendent, daily hand-delivered mail, a fitness room, central laundry, and private storage when available. The building's policies are owner-friendly within a pre-war framework: pets are welcome, with no breed restriction; pied-à-terre purchases are permitted; financing of up to 80% is allowed; and a 2% flip tax is paid by the seller. Subletting is permitted on a measured basis — generally one year with a renewal option — preserving the building as a primarily owner-occupied community. The cooperative has historically carried healthy finances with no standing assessment.

With only 36 apartments, turnover at Beekman Mansion is low — often just a handful of resales in a given year, and frequently fewer. Scarcity is part of the value: homes here do not come to market often, and when they do, the duplex maisonettes and high-floor units draw the most attention. Pricing reflects the Beekman premium for quiet, river-adjacent, white-glove pre-war product. The live /sales record for this BBL captures recorded transfers as they occur; for current value, compare against the building's own history and the closest Beekman and Sutton Place co-ops.

This is a co-op purchase, so a board package and interview are part of the process — plan for it. The building's published posture is buyer-friendly relative to many pre-war peers: up to 80% financing, pied-à-terre ownership allowed, and pets welcome. The 2% seller-paid flip tax is a known cost to factor into resale math. Diligence should focus on the financials, the reserve, any planned capital projects, and the specifics of the apartment — a maisonette duplex and a high-floor simplex are very different propositions. We help buyers read the building, prepare a clean board package, and benchmark the price against true Beekman comparables.

Scarcity and setting are the story. A home here is sold on the Beekman address, the quiet cul-de-sac, the white-glove service, and the building's financial health — and the comparison set is the small universe of Beekman and Sutton Place pre-war co-ops, not the louder avenues to the west. Maisonette duplexes and high-floor homes with river orientation should be marketed on their distinct character. Pricing to the building's own recent closings and presenting the apartment's pre-war proportions accurately are what produce a strong, efficient sale.
