The Think! Architecture design for the affordable housing project at 581 Grant Avenue was selected as part of the winning project proposal that was submitted in response to a Request for Proposals from the New York City Department of Housing Preservation and Development and is currently in the design phase of development. The RFP mandated the use of modular construction as a means of bringing much needed housing to the market more expeditiously and at lower cost than by conventional means. The project, which will provide 167 affordable units ranging in size from studio apartments to 4 bedroom units, has been designed to maximize the benefits of modular construction. All of the building’s residential modules are the same size to facilitate ease of fabrication and on-site construction and, to further minimize cost, the number of unique modules for stairs and other interstitial common spaces have been kept to the absolute minimum At the same time, the building has been designed to provide an innovative exterior massing and a façade treatment intended to mitigate the scale of the building in its low-rise residential context through a distinctly modern vocabulary that takes the building’s modularity as its starting point. Landscaped areas play a significant role in the overall project design with a diversity of outdoor spaces supporting a range of uses for the building’s residents as well as for the surrounding community. These spaces include rooftop terraces, a new exterior passage connecting the community to the subway station head house directly adjacent to the project site, a public plaza and private ground level gardens and recreational areas. Additionally, the project prioritizes sustainability through building orientation, the use of energy efficient systems and renewable and resilient building materials. The building, when complete, will exceed the requirements of Enterprise Green Community standards as mandated by HPD.
