At Jigsaw, we focus exclusively on prefab and modular construction. Why this singular focus? Because true expertise comes from specialization. For us, every project is a prefab project — not a one-off or an experiment. This approach allows us to continuously improve and refine our processes, as we have been dedicated to this field since 2016.

The project delivery method for modular and prefab construction is distinct. Are we the installer, the general contractor, or a subcontractor? The answer depends on the specific needs of the client and the project.

Each project is a unique puzzle, and it's our job to solve it.

We had the opportunity to host a construction manager from Marin County for a tour of one of our projects. After an extensive discussion, they shared, “I’ve been wanting to implement prefab and modular construction on my projects for years. I’ve toured several factories, but the one question that was never clearly addressed was, ‘Who will assemble all the components to create a finished project?’ Today, I have my answer — it’s you. You are the ones who put everything together and make it all come to life.”

To which we responded, “Yes, that sums it up perfectly.”
