We've decoded the construction process in California. By moving production off-site and into the lab, Fast Struct delivers precision-engineered modular and panelized homes without the chaos of traditional building
We don't force you into a box. We choose the construction method that fits your site, your design, and your timeline
The Modular Route
Ideal for rapid deployment. We manufacture fully finished 3D volumes-including structure, electricity, and finishes-in our factory. They arrive on your site ready to connect
- •Instant delivery & quick turnaround
- •Maximum noise reduction on-site
- •Projects requiring absolute predictability
The Panelized Route
Ideal for design freedom. We manufacture precision-engineered 'Smart Walls' that pack flat and assemble rapidly on-site. This allows for wider spaces and access to difficult lots
- •Complex architectural designs & open layouts
- •Sites with limited access (narrow roads/cranes)
- •Clients seeking a custom footprint
From a single backyard unit to a full-scale development, our technology adapts to your vision
Instant Space
Speed & Minimal Disruption
Add a premium living space to your California property without the headache of a long construction site. Our modular ADUs arrive 95% complete and are craned into place in a single day-keeping your backyard clean, quiet, and instantly usable
Uncompromised Living
Architectural Freedom & Performance
We bridge the gap between custom architecture and industrial precision in California. By using our Hybrid System (Panels + Modules), you get the design freedom of a traditional architect with the speed and superior insulation of factory-built modular and panelized homes
Precision at Scale
Faster ROI & Consistent Quality
For developers, time is ROI. Fast Struct streamlines the path from permit to occupancy. As a licensed contractor with complete A-Z solutions, we replicate high-quality units with millimeter accuracy, significantly shortening project timelines and reducing on-site management overhead
