Rialto, CA
Factory-built construction scales beyond the single-family home.
Rialto Apartments is a 16-unit multifamily project that illustrates how the 4C approach can scale across repeated residential layouts, using the 4C ECO™ wood-framed system.
Rather than framing each wall entirely in the field, 4C brings construction into a controlled manufacturing environment. Building components are engineered, manufactured, and organized as a coordinated system before arriving on site—helping simplify field installation and reduce dependence on conventional site-built framing.
The same approach, unit after unit.
For multifamily developers and contractors, the same approach can be repeated across units and building types, creating opportunities for more predictable quality, faster assembly, and reduced onsite labor.
Repeatable by design
The same coordinated system scales across units and building types, without reinventing the process for every floor plan.
Predictable quality
Factory-controlled manufacturing keeps every unit built to the same documented, repeatable standard.
Reduced onsite labor
Shifting a significant share of framing off site means less field labor and faster assembly at scale.
Wood-framed, built to scale.
4C ECO™ combines wood framing with continuous insulation and a factory-controlled manufacturing process. The system is designed to integrate into conventional construction while shifting a significant portion of framing work off site.
