Jeffrey Sommers, the architect who designed the LEED Platinum-certified C3 Prefab modular home—the first of its kind in Chicago—worked on the concept for four years. The name C3, derived from "Cube, Cut, Copy," has a math vibe consistent with the name of Sommers’s firm—Square Root Architecture—and the steps taken to conceive the original prototype.

House Tour: Chicago's C3 Modular House

Jeffrey Sommers's C3 Prefab modular house is a landmark of new urban architecture—and the first of its kind in Chicago. Although the structure was quick to construct, its genesis was less straightforward, involving (among other challenges) some accommodations to comply with city building codes and a little tweaking of the 2039-square-foot interior to better suit the homeowners' needs and fit the 25' x 125' lot. Compact, light-filled, and loaded with energy-saving features such as solar thermal panels, ductless heating and air conditioning, and water-conserving appliances, the house has a HERS rating of 46 and LEED Platinum certification. To learn more, come join us on a tour of the house.
