What We Build
Every project,
done right.
Where Every Project Begins
Every project starts with
the design and blueprints.
Before a single wall goes up, your project is fully designed, engineered, and permitted. Arc handles architecture, structural plans, Title 24 compliance, and all city submittals — so you arrive at construction with a complete, approved set of drawings.
Architectural drawings and full construction documents
Structural engineering and Title 24 energy compliance

Design-only engagements available — plans without construction

Client Stories

"
Arc completely changed how I thought about the renovation process. I knew exactly what I was getting — and what it would cost — before we ever broke ground.
"
The kitchen is beyond what I imagined. The team was communicative, on schedule, and the Arc Studio portal made it so easy to track everything.
"
We added 400 square feet and it looks like it was always there. The craftsmanship is exceptional. These guys actually care about the finished product.
