Room Addition Types We Frame in the Bay Area
Every addition is different. We've framed them all — and we know the Bay Area building requirements for each.
Family Room Addition
Add living space for a growing family. We frame single-story additions that tie into your existing home structure seamlessly.
Master Suite Addition
A private master bedroom and bathroom addition. Proper framing means sound isolation, correct ceiling heights, and code compliance.

Adding a floor to your Bay Area home requires structural engineering. We work with your engineer and frame the second story right.
In-Law Suite
A semi-independent suite addition for family members. Proper framing includes soundproofing-ready wall assemblies and separate entry.
Home Office Addition
Dedicated home office space added to your footprint. We frame it to match your existing home's design and structure.
Sunroom / Flex Space
Light-filled additions with large window openings and proper structural headers. Engineered to span the Bay Area's seismic requirements.
