The prototypes are single-family homes completely off-grid with electricity and potable water. They were designed by New York City and Puerto Rico-based Marvel Architects and paid for by nonprofit Acacia Network. The homes utilize hurricane and seismic-resistant components, which include an insulated concrete panel system that has shown to be just as if not more effective against earthquakes than traditional concrete block construction. They also employ passive design strategies, allowing natural cross ventilation, heat extraction, and shade. In addition, the structures are modular so that they can adapt to a variety of locations and square footage.

Jonathan Marvel, the firm's founder, addressed the cost of these resilient homes with Fast Company's Adele Peters stating, "I don't want to say 'affordable,' because the average Puerto Rican income is below the level of poverty in the United States. So this is a housing system that's going to require assistance to build." Marvel added that families receiving financial assistance to construct these homes and installing solar panels "should be as routine...as it is to buy a car."

According to Peters, Acacia Network plans to build 1,000 of these homes across Puerto Rico. The first two prototypes are expected to be inhabited soon.
