What happened

New York YIMBY reported on 11/01/2026 on three residential projects in Park Slope, Brooklyn. All three are within walking distance of the F, G and R trains at the 4th Avenue-9th Street station and the R train at the Union Street station along 4th Avenue.

The largest is The Grand Prospect at 263 Prospect Avenue, near the corner of Prospect and 5th Avenues, on the site of the former Grand Prospect Hall. The five-story, 50-foot-tall building will have 150 rental units in one- to three-bedroom layouts. It was designed by Hill West Architects and developed by Angelo and George Rigas. Work is wrapping up. Landscaping and new sidewalks are in place, and crews are finishing the interiors and front entrance. Planned amenities include a fitness center, golf simulator, lounge and event space, children's playroom, business suite, pet spa, rooftop with grilling stations, bike storage and a parking garage.

At 403-405 5th Avenue, at the corner of 7th Street, demolition is ramping up for a five-story mixed-use building designed by DXA Studio. It will have 12 apartments, amenities and ground-floor retail. Crews are gutting the existing low-rise buildings behind a sidewalk shed. Completion is estimated for the spring of 2028.

At the corner of 6th Avenue and 2nd Street, demolition is complete on the 7,200-square-foot former site of the St. Matthew Evangelical English Lutheran Church. Five four-story townhouses are planned, to be addressed as 300, 302, 304 and 306 6th Avenue and 435 2nd Street. Each will span 2,900 square feet with a cellar. The Brooklyn Home Company and MESH Architectures are designing them. Excavators are on site, but earthwork has not begun, and no timeline has been released.

What it means

Tenants and voucher holders

The Grand Prospect will add 150 rental units near several subway lines, and work is nearly done. The report does not say what rents will be or whether any units are income-restricted.

Landlords

Owners of rentals in Park Slope may soon see 150 new amenity-heavy units competing for tenants nearby. Twelve more apartments are expected at 403-405 5th Avenue, with completion estimated for the spring of 2028.

Caseworkers

Nothing in the report says any of these units are affordable or set aside for voucher holders. Clients interested in The Grand Prospect would need to watch for its leasing details.

The highlights

  1. All three sites are near the 4th Avenue-9th Street station on the F, G and R trains.
  2. The R train also serves the projects at the Union Street station on 4th Avenue.

Why it matters Landlords

New rental supply near 4th Avenue transit could add competition for Park Slope landlords and new options for renters.

What to do: Watch for unit counts and lease-up dates on these 4th Avenue projects.

Not known yet

  • Asking rents and whether any units at The Grand Prospect are affordable or offered through a lottery

Background

In New York City, new buildings that include income-restricted units usually market them through the city's Housing Connect lottery, with income limits and rents posted in the listing. Market-rate buildings lease directly through the owner or a broker. Under the NYC Human Rights Law, landlords and brokers generally may not refuse an applicant because they pay rent with a housing voucher such as Section 8 or CityFHEPS.
