140 Eighth Avenue is the Art Deco building in a neighborhood that otherwise stops at 1910. Park Slope's architectural reputation rests on brownstone, limestone and the Romanesque and Renaissance Revival mansions that line Eighth Avenue and Prospect Park West. This building belongs to a different decade and says so from the sidewalk: orange brick over a limestone base, limestone moldings run in bands across six stories, a canopied entrance with patterned glass doors, and black steel casement windows still in place. Two lobbies — the building has more than one entrance off its courtyard frontage — carry murals and terrazzo floors of the same moment. Nothing else of this size or vocabulary exists inside the district.
Its arrival was the tail end of a specific transaction that ran through 1930s Park Slope. The great single-family houses on Eighth Avenue had become economically impossible by the Depression, and one after another they were sold, cleared and replaced with apartment houses that could put fifty or a hundred households on the same ground. Martyn N. Weinstein's 1935–36 design for Garfield Construction Corporation is one of the last and largest of those replacements, occupying a full 24,000-square-foot corner at Carroll Street and running back toward Fiske Place. It is worth noticing that the building was not required to fill its lot: the courtyard setback that gives the apartments their light was a design choice, and it is the reason a six-story building on this site produced a floor-area ratio of just over 4 rather than the maximum the era allowed.
Landmarking in 1973 froze both the building and its context. Under the R7B contextual zoning that now governs the block, permitted bulk is 3.0 FAR; this building carries roughly 4.1. Nothing of this size will be built beside it, and its own envelope — including those casement windows, which are the single most consequential capital item at the address — is subject to Landmarks review.
The cooperative is the oldest of the neighborhood's big-building conversions. Garfield Associates transferred title to 140 8th Avenue of Brooklyn Corp. in February 1980, ahead of the wave that converted most of Park Slope's rental prewars over the following six years. Forty-six years of shareholder governance means a long, self-generated financial record and a board that has run every capital cycle at least twice — an underwriting advantage worth putting to work in a deal.
Architecture and unit composition
The building holds 94 apartments across six stories on a corner lot of 24,000 square feet, with roughly 97,800 square feet of floor area. The plan is organized around courtyards rather than a single lobby axis, which is why the building reads as lower and quieter from Eighth Avenue than its unit count suggests, and why interior apartments get real light instead of an airshaft.
Layouts follow the mid-1930s standard that these buildings were built to rent: entry foyers, defined living and dining rooms, bedrooms off a hall, and closet counts that are generous by prewar standards — a frequent and legitimate selling point in individual apartments here. The Art Deco detail that survives inside varies apartment by apartment, from original tiled bathrooms and arched openings through to full gut renovations, and that variance is the primary driver of price spread within the building. Because the black steel casements are original and character-defining, replacement is a Landmarks matter and not a shareholder decision; ask what the co-op's window policy is and whether a building-wide program has been discussed.
Building operations
140 8th Avenue of Brooklyn Corp. has operated the building since the 1980 closing. The service model is the district's standard for a large interwar co-op — resident superintendent, elevator service, central laundry, basement storage, and a common room that doubles as a children's playroom and meeting space — with no doorman. Ninety-four apartments spread the fixed costs of that operation more efficiently than the district's forty- and sixty-unit buildings do, which is a structural advantage in the maintenance line.
The capital agenda at a 1936 masonry building is legible and expensive: FISP/Local Law 11 façade cycles, roof and parapet, boiler and riser stack, elevator modernization, and the courtyard and areaway work that a set-back building carries and a streetwall building does not. Steel casement windows are the item that separates this address from its peers — restoring or replacing them under Landmarks review is a significantly different project than a vinyl replacement program three blocks outside the district. Ask management for the current capital plan, the last two FISP filings, the assessment history and the corporation's underlying mortgage terms.

What to know if you’re buying
The windows are the file to read. Original black steel casements inside a historic district are a Landmarks matter, a thermal-comfort matter and a capital matter all at once. Find out what the co-op's policy is and whether a program is planned or funded.
Every policy is an open question until management answers it. Pets, sublets, flip tax and financing standards are not on the public record for this building. Ask for all four in writing before you make an offer.
Buy the exposure. Avenue, courtyard and Carroll Street lines behave differently on light and noise. Walk the specific apartment at the hour you care about.
Scale is a carrying-cost advantage. Ninety-four apartments carrying a superintendent, an elevator and a laundry is a better ratio than the forty-unit buildings nearby. Test that against the actual maintenance number and the assessment history.
Reconcile original condition with your renovation budget. Surviving Deco detail is part of what you are buying and part of what you may need to work around. Price both.
What to know if you’re selling
Lead with the architecture and name the architect. Martyn N. Weinstein's 1936 Art Deco design, the limestone base, the murals and terrazzo in the lobbies, the courtyard setback — this is the rare Park Slope co-op with a genuine architectural headline. Use it.
Photograph the lobbies and the courtyards. They are common elements every buyer walks through and the strongest visual differentiator against competing listings on Seventh and Eighth Avenues.
Have the building's answers ready. Because the policy framework is not public, the seller who can hand a buyer written confirmation of the pet, sublet, financing and flip-tax rules removes the friction that otherwise stalls these deals.
Comp on exposure and condition, not on building average. A renovated courtyard-facing apartment and an original avenue-facing one are different assets. Anchor to matched 2025-forward comparables.
