A builder who
gets design.
Rooted in design.
Plant started as a residential design studio, collaborating with Ray Kappe, FAIA, KieranTimberlake, and other leaders in the field to design and build homes more efficiently. For more than a decade we struggled to find prefabricators who understood design and could consistently meet our standards for quality and sustainability. We founded Plant as a solution.
Your vision, built to spec.
Plant is a new kind of homebuilding factory and system, optimized to work with architects on custom projects. Our mission is to make it easy and efficient for your clients to build the incredible homes you design for them.
We developed design guidelines to help architects understand the process, and we work with you to ensure that your client’s project is built to your exact specifications.
Fast and reliable.
Building with Plant cuts construction time in half. Advanced engineering exposes design or structural issues before production even begins, and building happens in tandem with site work. Construction is indoors, with all trades in-house, and inspections are conducted right in our factory.
Consistent, superior quality.
We build in a controlled environment, with highly-skilled, full-time staff adhering to strict quality control procedures. Ray Kappe, Brooks + Scarpa, Yves Béhar, Kieran Timberlake, Toby Long, Sage Modern, and M-Rad are among the many architects and designers who have entrusted their projects to Plant.
Here’s the full process.
Bid & Feasibility
Project Bid
You’ll share your client’s project and we’ll prepare a rough order of magnitude (ROM) bid that specifies anticipated costs, inclusions, and exclusions.
Time: 1 - 2 weeks
Initial Design Review
You’ll share your plans and we’ll make sure they can be prefabricated at Plant. Our design studio will give you a sense for what kind of changes may be required, if any, to make your design more modular-friendly.
If you haven’t yet reviewed our design guidelines for architects, this is a great time to do so.
Time: 1 - 2 weeks
Land Feasibility
We will evaluate your client’s lot, and the route from our factory to the lot, to make sure it’s feasible to deliver and install prefabricated components. In general, if a foundation can be engineered, we can install prefabricated modules on it. However, impediments like overhanging trees and power lines, low bridges, narrow roads, severe curves, and steep slopes along the route will determine what we can build and deliver. We'll give you a full report and discuss our recommendations.
Time: 2 weeks
Design & Engineering
Design
If you’ve already completed the design, we’ll work with you on any changes that may be required to make it more efficient for prefabrication. Ideally, you connect with us before your plans have been engineered, as the requirements for offsite construction vary from those for site-built projects.
If you’re still developing the design, we’ll help you optimize it for prefabrication and weigh in on the most cost-effective, healthy, and sustainable options for finishes, fixtures, and other materials.
Time: 12 - 16 weeks
Engineering & Permitting
Engineering and permitting for the house modules are governed by state authorities. Engineering and permitting for the foundation and site work is governed by local authorities.
You (or your client’s general contractor) will coordinate engineering and permitting. Plant can support you by recommending engineers who are experienced in prefabricated construction.
Time: Varies by jurisdiction
Pre-Construction Agreement
Pre-Construction
This is when you and your client finalize finish specifications, and when we work with you and/or your client to determine the scope of work between Plant and your client’s site general contractor. Based on our decisions, we finalize pricing for the production. This is also when we collate and submit the engineered drawings for the modules to state authorities for permitting.
Time: 8 - 16 weeks
Fabrication & Site Work
Fabrication
Your client’s project is built in our indoor facility by our highly-skilled, full-time tradespeople, following precisely engineered plans. Our rigorous quality control program ensures superior craftsmanship, and our environmental health and sustainability standards minimize toxins and waste.
Production happens in parallel with site work, shaving months off the project timeline. And, all required inspections are completed in Plant’s factory, so we’re able to deliver your client’s project with the walls sealed and finishes installed!
You and your client are invited to tour the project in production.
Time: 8 - 16 weeks
Site Work and Foundation
Plant does not perform site work, but we collaborate with your client’s site general contractor on the preparation of their lot and foundation. We provide direction, answer questions, and work swiftly to resolve any issues, maintaining oversight and quality control of the entire process.
Time: 8 - 16 weeks
Installation to Move-In
Delivery & Installation
Your client’s general contractor will select a transportation company and schedule delivery of the modules. Plant can introduce the general contractor to recommended transportation providers if needed. The transportation company will secure any necessary permits (for things like police escorts, road closures, or parking), and truck the modules from Plant’s factory to the job site.
Then for the fun part! Installation is when the modules and other prefabricated components that comprise the home are assembled on-site. A crane is used to lift the modules off the truck and then lower them onto the prepared foundation, where they are bolted together. Depending on the size and complexity of the design, most projects are fully assembled in a matter of hours. (Really.) It’s cool to watch, and you’re invited to spectate! Here’s a video that shows the process.
Time: 1 - 2 days
Finish Work
Once the building is assembled, your client’s general contractor will connect the water, sewer, electric, and appliances, and apply the finishing touches (like exterior siding where the modules were connected). Since most Plant projects ship 90% complete, with drywall, paint, millwork, tile work, and even the appliances already in place, on-site finish work is generally minimal. Landscaping is also typically done at this time.
Time: 6 - 12 weeks
Final Inspection
The city will perform the final inspection to ensure that the structural and utility connections were done correctly and then issue the certificate of occupancy. Your client’s project is officially complete!
