Home Additions
Room additions and second stories that look like they were always there.
The mark of a great addition is that nobody can find the seam. We match rooflines, siding, stucco texture, and window styles to your existing home, and we handle the structural engineering, foundation work, and Title 24 energy compliance that additions in California actually require.
Primary suites, family rooms, home offices, and second-story additions — from design and permits through the final coat of paint, one accountable team.
Available in Redwood City , Palo Alto , Menlo Park , San Jose , Sunnyvale .
