This 480 SF custom panelized addition in Stevensville, Montana is a perfect example of how Green-R-Panel supports homeowners looking to expand their existing living space with efficiency and confidence. Nestled in the scenic Bitterroot Valley, this compact yet impactful addition was designed to blend seamlessly with the original structure while accelerating the build timeline.

The Green-R-Panel kit included an I-Joist floor system, custom-manufactured wall panels, and engineered roof trusses, all pre-engineered to meet Montana’s building codes and energy efficiency guidelines. With rapid on-site assembly and minimized material waste, this panelized system allowed the homeowner to complete their expansion faster and with fewer complications than traditional framing.

From guest suites to home offices or extra living areas, Green-R-Panel makes it easy to add value, space, and function—without starting from scratch.
