Room & Second-Story Additions in Mountain View
Add the space your family needs without leaving the neighborhood you love — we design and build additions that look original to the home.
In a market like Mountain View, adding space is often smarter than moving. Whether you need an extra bedroom, a bigger kitchen, a primary suite, or a whole second story, we design and build additions that expand your home and blend seamlessly with what is already there.
Additions are structural work — foundations, framing, and tying into existing systems — so engineering and permitting matter. We handle design, structural engineering, and City of Mountain View permits, then build it right.
- Single-room and multi-room ground-floor additions
- Second-story additions and primary-suite expansions
- Foundation, framing, roofing, and exterior matching
- Full engineering and permits handled for you
We build with trusted, professional-grade brands

Frequently Asked Questions
Have a question we didn't answer? Text us and we'll get right back to you.
Do I need permits for a home addition?
Yes — additions require permits and usually structural engineering. We handle the full permit and engineering process with the City of Mountain View as part of the project.
How long does a home addition take?
Ground-floor room additions typically run 2 to 4 months; second stories take longer. We provide a realistic schedule after design and engineering.
Can you match my existing home?
Yes. Matching rooflines, siding, windows, and finishes so the addition looks original is a core part of how we build.
How much does an addition cost?
Additions are quoted per project after design and engineering. We provide a fixed written estimate — text us to begin.
