Digsau, an architecture firm out of Philly, worked with Oldcastle Precast to come up with this $99K house entry, which uses some concrete technology more commonly encountered in Houston area civil structures:
A concrete module serves as the building block for the system, and its combination with other modules allows the structure to respond to specificities of climate, site, and individual preference. The system thus proves highly adaptable as an infill structure on vacant properties in an urban context and allowing for a diversity of exterior space in new developments.
