The goal of Anshen + Allen’s A-100 House is to advance the paradigm established by Joseph Eichler, who began developing affordable single-family homes in 1949. Eichler homes capitalized on the prudent assembly of post-and-beam building systems: The A-100 House attempts to take this idea further by allowing residents to tune their homes to their own spatial and environmental needs. Anshen + Allen’s prefabricated solution includes preassembled components that can be easily transported to the site, and a foundation system consisting of precast footings that support precast concrete floor panels. The floor system is panelized, as are the wall and roof assemblies. The exterior wall panels are insulated to provide energy-efficiency and the roof incorporates photovoltaics to generate electricity.

With the exception of site adaptation, the A-100 comes preassembled. Site excavation and a small portion of the foundation system construction would take place onsite.
