A Private Pricing Opinion — what your apartment at 21 Butler Place 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.
21 Butler Place is a four-story prewar walk-up with an unusually elaborate lobby for a building dominated by compact apartments. Marble walls, ceiling moldings, patterned tile flooring and a mirrored mantelpiece survive in the entrance hall. The property forms one half of the 15–21 Butler Place cooperative.
The apartment inventory includes small one-bedroom homes and larger two-bedroom layouts. A common roof deck supplies outdoor space above the upper floor, with skyline views. The top-floor apartments require three flights of stairs above the entrance level.
Butler Place is a short street near Grand Army Plaza, connecting Plaza Street East and Sterling Place. The 2 and 3 trains are nearby, and Prospect Park lies beyond the plaza. The building's location also places it close to the Brooklyn Museum and Botanic Garden.
Architecture and unit composition
The residential building dates to 1915 and has approximately 73 feet of frontage. Its lobby retains decorative finishes that establish the original apartment-house character before the stairs lead to the residential floors.
Recorded apartment areas include compact homes around 375 to 500 square feet, larger one-bedroom layouts around 625 square feet and two-bedroom-sized homes around 770 square feet. The one-bedroom label therefore covers notably different amounts of interior space.
Layouts include entrance foyers, open kitchens and windowed bathrooms. Some rear apartments look over adjoining gardens. Corner apartments can have more than one exposure, while street-facing rooms have an outlook toward Butler Place.
Wood flooring and high ceilings appear throughout the resale inventory. Renovated apartments have changed kitchens, bathrooms and closet arrangements, while portions of the original trim remain. The more spacious two-bedroom plans provide a different total-area category from the compact one-bedroom stock.
Building operations
The cooperative owns both 15 and 21 Butler Place on separate tax lots. The common ownership entity is the same, even though each address has its own building and residential count. This page covers the cooperative through the 21 Butler Place address.
An off-site superintendent serves the building. Common laundry and bicycle storage are in the basement, with storage cages available separately. The roof deck is shared among residents.
Confirm permission for a proposed in-unit washer/dryer installation with the managing agent.
Policy framework
Subletting: Permitted subject to the cooperative's terms — confirm with the managing agent.
Purchase structures: Parental purchasing, co-purchasing and gifts are considered — confirm with the managing agent.

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.
