Frameless Building Solutions-
No Wood, No Drywall

Looking for a smarter way to build? At GR Building Systems (Green Rhino), we provide frameless building solutions that eliminate the need for traditional wood framing and drywall—offering unmatched efficiency, strength, and resistance for your home or commercial build.

Our system is built on high-density EPS foam panels coated with our proprietary structural concrete-like finish. These panels form the entire wall, floor, and roof systems, creating a building shell that’s fire-resistant, mold-resistant, flood-resistant, and hurricane-tested—without a single wood stud or sheet of drywall.

If you’re tired of rising lumber prices, long build times, and materials that can warp, rot, or grow mold, it’s time to consider a frameless construction system designed for today’s challenges.

Why Go Frameless?

Traditional construction relies heavily on wood framing and drywall—materials that are vulnerable to moisture, pests, and fire. Our frameless building system eliminates those risks and offers a streamlined, modern approach to structural design.

Here’s why Arizona builders and homeowners are switching to Green Rhino:

No wood framing = no warping, splitting, or termite damage
No drywall = no sanding, taping, or interior framing labor
Fire-tested and code-approved for structural integrity
Superior insulation leads to up to 75% energy savings
Fast assembly with no heavy machinery required
Designed for extreme heat, high winds, and natural disasters

Whether you’re planning a custom home, studio, casita, or full-scale development—our frameless system delivers modern performance with long-term value.

How It Works

We custom-cut each EPS foam panel to your design, allowing for tight tolerances and simple on-site assembly. Panels are glued into place—no nails, screws, or framing needed.

Once assembled, our team applies a concrete-like structural coating, embedding our high-impact mesh for strength that exceeds traditional framing. This coating forms the shell of your building—solid, sealed, and ready for finishing.

Key features:

Structural wall, floor, and roof panels with thermal and acoustic insulation
Seamless envelope design with minimal air leakage
Impact-tested to withstand hurricane and tornado forces
Ideal for desert climates and energy-conscious builds

Applications for Frameless Builds

Our system is flexible enough to support nearly any structure, including:

Residential homes
Detached casitas and ADUs
Studio spaces and backyard offices
Commercial and modular buildings
Schools, cabins, and bunkers

With no reliance on lumber or drywall, you can build smarter, faster, and stronger—without compromising design or durability.

Let’s Build the Future—Frameless

Frameless doesn’t mean featureless—it means forward-thinking. If you’re planning a project and want a clean, efficient, and resilient alternative to old-school framing, let’s talk.

Our team at GR Building Systems is here to walk you through the process, show you samples, and explain how our no-wood, no-drywall method can save you time and money while delivering elite performance.
