About & our process
A simpler way to build.
Campbell Building Solutions is a Southern California general contractor led by Matthew Campbell. We take commercial and residential projects from an idea to a buildable plan, then manage the build.

From Matthew Campbell
Why I started this company
Rooted in faith, raised in the South Bay, and surrounded by family, I gained a lot of experience in understanding stress and handling problems with ease. With 10 years in the trades, I've seen the struggles and stress a developer, business owner, or homeowner goes through in the process of making their property more than what's on the plans.
That's why I started Campbell Building Solutions — to make the construction process easier, and to see the vision the way we do.
I've worked in almost every part of the building process, from land clearing to finish carpentry. Not just learning bits and parts of each, but truly gaining knowledge of what goes into the trade and, most importantly, what mistakes are often made along the way. That's how I learned to streamline a project — so you can see the beauty behind the mess and feel the relief that comes with building the Campbell way.

How it works

Share your vision
Tell us what you want to accomplish — the space, the goal, the timing. Rough ideas are a fine place to start.
- 02
Develop the plan
We translate that vision into a clear direction and plans, so scope, priorities, and next steps are on paper.
- 03
Refine together
We review it with you and revise until it fits how you'll actually use the space. You make the key calls; we keep them clear.
- 04
Build
We manage execution day to day and keep you informed, bringing the project to life without you having to run it.
