Greenwood Building Materials
Our Story
Greenwood Building Materials was born from a simple realization: the dream of homeownership is slipping away for our generation. Founded in 2023 by nine cousins in their late twenties and early thirties, we experienced firsthand the rising barriers to entering the housing market. We saw our friends and peers facing the same struggle, and we knew something had to change.
From Heritage to Innovation
Building is in our blood. With several of our parents coming from deep construction backgrounds, we were pointed toward a sustainable solution: green building products. We realized that by focusing on smarter, more efficient materials, we could address both the environmental impact of construction and the soaring costs that keep people out of homes.
Two Years of Dedication
We didn't just want to enter the market; we wanted to change it. We spent two years in intensive Research & Development, exploring sustainable solutions that don't compromise on quality or durability. With the unwavering backing of our family and by pooling our own capital, we have officially brought Greenwood Building Materials to the market.

The Green Vault
Georgia's Statewide Styrofoam Recycling
Turning Local Waste into Stronger Communities
At Greenwood Building Materials (GBM®), we believe that true sustainability begins at home. The Green Vault is our statewide recycling initiative designed to divert hard-to-recycle materials such as expanded polystyrene (Styrofoam™), glass, and industrial aggregates away from landfills and transform them directly into affordable, high-performance building supplies. Through the Green Vault program, Georgia's waste is re-engineered into energy-efficient Insulated Composite Concrete Form (ICCF) Blocks.
Community Collection Hubs
We partner with local municipalities, businesses, and community organizations to set up accessible Green Vault drop-off sites across Georgia.
Advanced Upcycling & Manufacturing
Collected materials are processed using our proprietary methods. EPS foam is shredded and combined into ICCF blocks, while post-consumer glass is converted into sustainable drainage aggregates.
Building Generational Wealth
Upcycled materials are supplied directly to local housing developments, including our Housing Revolution Tour initiatives, drastically lowering construction costs and creating local green jobs.
Materials We Accept
- Expanded Polystyrene (EPS)
- Clean Styrofoam packaging
- Coolers
- Insulation boards
Please ensure all dropped-off foam products are clean and free of tape, food residue, or metal attachments.
