Plant Prefab

Plant Prefab manufactures custom single and multifamily homes that are high-quality, sustainable, healthy, and durable. We empower individuals, architects, and small developers who want to build their own projects – and who want an efficient and reliable solution. And peace of mind during the process. We work with your architects on your custom designs or you can work with our Design Partners or select Standard Homes they have created for us.

We are the first home factory in the nation dedicated to sustainable construction, materials, processes, and operations. We believe homes can and should be built in ways that minimize their negative impact on energy, water, resources — and the health of the people who live in our homes and who build them. We know that in-factory construction can be faster, more cost-effective, and more reliable than on-site construction. And we know it saves neighborhoods from months of noise pollution, traffic and disruption.

Plant was spun out of LivingHomes, a design and development company that’s built dozens of award-winning prefabricated homes, including the nation’s first LEED Platinum home. Leveraging LivingHomes’ experience with ten factories over the course of eleven years, we’ve learned a lot about what works and what doesn’t. Plant Prefab reflects many lessons and best practices. Major funding was provided by Obvious Ventures, a venture fund that focuses on #worldpositive investments. Our first factory is a 62,000 sf facility in Rialto, California.

Plant Prefab and LivingHomes are committed to supporting those who have lost their homes in this year’s devastating wildfires. To show our support, we are offering discounted services and free upgrades.

LivingHomes is a designer and developer of modern, prefabricated homes that combine world-class architecture with an unparalleled commitment to healthy and sustainable construction. The first LivingHome, designed by Ray Kappe, FAIA, was installed in eight hours. It became the first home ever to receive a LEED for Home Platinum rating. Twenty-four LivingHomes have been or will soon be certified LEED Platinum and one LEED Gold, making the company one of the most experienced designers of homes at the highest level of LEED certification.

LivingHomes, which was recently awarded the Sustainable Quality Awards Grand Prize, have garnered significant industry recognition including the AIA’s top sustainable award, Green Builder Magazine’s Home of Year, Business 2.0 “World’s 11 Coolest Products”, and Business Week’s “Architectural Wonders of the World.”

LivingHomes and Plant Prefab are committed to supporting those who have lost their homes in this year’s devastating wildfires. To show our support, we are offering discounted services and free upgrades. Choosing from one of our standard plans can get you into a home as fast as possible. If you prefer, you can work with us to design a custom LivingHome.
