Advancing residential

Plant Prefab was founded to make it faster, easier, and more sustainable to build high-quality housing.

We'd spent a decade working with other housing factories, experiencing the drawbacks of conventional modular and panelized systems, and saw an opportunity for innovation. We recruited a team of experts from construction, architecture, and manufacturing and set out to devise a better approach.

The result is an infinitely adaptable panel-based building system, driven by advanced engineering and produced with state-of-the-art manufacturing. It’s a versatile, scalable building solution that flexes to fit diverse project designs and scopes, helping general contractors, architects, and developers deliver housing with industry-leading speed, quality, and sustainability.


Our Story

In 2006 we founded a residential design studio called LivingHomes. We focused solely on residential design for factory construction, partnering with leading architects working to push the limits of sustainable design and advance adoption of prefabrication techniques. 

The first home we delivered was the first home ever to achieve USGBC LEED for Homes Platinum certification, with many more to follow. Our projects won awards for design, sustainability, and construction innovation, shattering long-standing stereotypes of prefab construction and redefining the possibilities of factory-built housing. But we worked with ten different factories through the years and found that none were able to consistently meet our needs for design integrity, quality, and sustainability. 

We realized that in order to truly achieve our vision—to make it faster, easier, and more sustainable to build high-quality housing—we needed a building solution and manufacturing capabilities designed for this purpose. The idea for Plant Prefab was born.

Carbon-Neutral Operations

We were the nation’s first prefabricated home builder to make a carbon pledge and we’ve achieved carbon-neutral operations since 2020. 

Each year we take an in-depth audit of our operations, considering both embodied and operational carbon from primary, secondary, and tertiary sources. Then, we seek ways to continuously reduce emissions throughout our value chain, accelerating the transition to a net-zero carbon economy. 

Waste Reduction

In traditional construction, up to 40% of materials are lost to waste. We bring that down to almost zero. 

Our industry-leading material efficiency is driven by our advanced virtual design and construction process, which produces a precise list of materials and analyzes it for optimal usage. This allows us to order materials in the most efficient dimensions possible and allocate those materials in the most efficient manner possible. Precision cutting and manufacturing means no spoilage, and the waste we do produce is sorted for re-use or recycling, keeping valuable resources out of the waste stream. 

Healthy, Sustainable Materials

Building materials impact a home’s energy performance, indoor air quality, occupant comfort, and carbon emissions. That’s why we carefully evaluate each material we specify, considering product safety, performance, and environmental factors like recycled content and embodied carbon. 

Our USDA-certified, bio-based Type X drywall contains 95% recycled content and has the same strength and performance of standard drywall with up to 22% less weight for lower transportation fuel energy. Our exterior sheathing incorporates a water-resistive barrier and continuous foam insulation, so we can use less materials in each project while providing a more durable building envelope that increases energy efficiency. We use finishes with low or no volatile organic compounds (VOCs) and categorically avoid products with known carcinogens.
