Engineering Discipline Meets Master Craftsmanship — In Every Build.

Most homeowners are told what’s legal — not what actually makes sense for their property.

Residential construction, approached with engineering discipline.

We help Southern California homeowners plan and build legal ADUs, additions, and residential upgrades with long-term clarity.

About Us ->

  • Built from Experience — Not Buzzwords. Our co-founder spent years building complex engineering systems at scale before translating that discipline to construction.

  • Craftsmanship with Integrity. We don’t cut corners — we prevent them.

  • Clarity First. We help you understand what should be built before it ever starts.

  • Trusted Execution. We plan through permits, inspections, so your project doesn’t stall.
