This project is a multifamily affordable housing building that addresses the economic and demographic diversity of the site and permits adaptability to changing households. It proposes a modular construction co-op housing model that encourages homeownership through the growth and expansion of apartment units over time according to the needs of the residents. The proposed building promotes a self-sustainable community through different programs such as urban agriculture. A rooftop garden provides spaces for food to be harvested and then sold in a market on-site. The modular construction is facilitated through a permanent armature that contains structure, service spaces, and communal programs for the residents. The armature supports a variety of fixed and expandable units that wrap around two main courtyards that are accessible to both the residents and the public.
