Construction is finished on Kay’s Place, an 11-story mixed-use residential building at 487 4th Avenue in Park Slope, Brooklyn. Designed by Aufgang Architects and developed and built by Procida Companies under the 487 4th Avenue Managers LLC, the 107-foot-tall structure spans 49,308 square feet and yields 44 affordable rental units with an average scope of 864 square feet. The project also includes 2,154 square feet of ground-floor commercial space, a cellar level, and one enclosed parking space. Ten of the units are one-bedroom apartments for residents with developmental disabilities, and a portion of the remainder will be reserved for the formerly homeless. The property is located at the corner of 4th Avenue and 12th Street.

Exterior work fully concluded since our last update in September 2024, when the reinforced concrete structure was rising toward the halfway mark and façade installation had yet to begin. The structure stands finished in its envelope of dark gray brick surrounding a grid of recessed PTAC windows. The main entrance is positioned at the eastern end of the 12th Street elevation next to the garage door. The ground-floor commercial space has yet to be occupied.

The project is named in honor of Sister Catherine “Kay” Crumlish, the former executive director of the local non-profit Mercy Home, who sought to build housing on the site for several decades before her death in 2020. Funding was acquired in a collaboration with Mercy Home between the Department of Housing Preservation and Development (HPD) and the state Office for People With Developmental Disabilities.

The nearest subways from the ground-up development are the F, G, and R trains at the 4th Avenue-9th Street station to the south.

  1. Kind of dreary. Not bad though. A bronze colored cladding, or some other warm shade, for the window assemblies would have gone a long way in creating interest and livening up the overall aesthetic.

    Yes, it’s rather austere and the window mullions didn’t also need to be grey, but the basic design is better than average. Actual window screens is an amazing thing. But what is with the different mortar color at the base?

  3. and its in a great neighborhood
