Hot on the heels of a collaboration with Koto, California-based Plant Prefab is teaming up with St. Paul–based Alchemy Architects to launch a new line of modular accessory dwelling units (ADUs).
The lightHouse LivingHomes will be available in five categories—small, medium, large, extra-large, and 2X—that range from 310 square feet to 600 square feet. These flexible ADUs are available with a dozen floor plan variations—from a compact studio to a one-bedroom that can be built above a two-car garage.

"Having worked together to build two prior homes in California, we’re confident that Plant Prefab is the right partner to bring our ADU designs to this market," says Geoffrey Warner, Principal Architect at Alchemy and weeHouse Founder. "The lightHouse is intended to be a beacon for sustainable living; Plant Prefab has built up its reputation around sustainable building practices."
Alchemy’s 15-plus years of experience with their prefab weeHouse line informed the design of the lightHouse, a flexible ADU that celebrates the motto "Luxury of Less."
The first Plant Prefab–built modular lightHouse ADU was completed earlier this spring in Sebastopol, California. This 423-square-foot lightHouse was completed for around $285,000. That figure breaks down to approximate costs of $210,000 for design, engineering and production; $60,000 for infrastructure and site work; and $15,000 for shipping and installation.
