About the building
Two separate limestone houses were joined in a condominium conversion whose filing became effective in 1986. At 11, John H. Duncan's design places an arched entrance beneath a stone balcony and finishes with a mansard roof. Charles I. Berg's house at 15 has a rusticated base, a projecting balcony and a roof balustrade. Both façades received individual landmark protection before the conversion. The commercial gallery occupies a distinct portion of the property.
The residences include smaller one-bedroom apartments, larger combined layouts, garden-level homes and duplex penthouses. Some retain fireplaces, tall ceilings and substantial room proportions from the mansion interiors. Outdoor space takes several forms, including patios, balconies and upper terraces; these are attached to particular homes. A staffed entrance and elevator serve the residential condominium.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01385-7501; each condominium apartment is its own tax lot).

Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price.

What to know if you’re buying
The residential and gallery spaces can be offered together, but their permitted uses remain separate. Gallery square footage should not be counted as residential accommodation without the required approvals. With a small residential ownership group sharing staffed service across two landmarked houses, the allocation of gallery and residential expenses is a material part of the purchase.

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.
