What types of additions do you specialize in?

The beauty of design-build is that we can create whatever your location and situation require. Here are a few of our most popular addition projects:

Full home expansions
Kitchen and bathroom additions
Second-story additions
Primary suites and in-law suites
Garage conversions and flex spaces
Aging-in-place and multigenerational layouts

How long does a home addition project take from start to finish?

The full timeline can range from 6 to 12 months, depending on permitting and complexity. Design typically takes 2–3 months; construction takes 4–6 months for most additions.

What’s the difference between a room addition and a home expansion?

A room addition typically adds one space, like a guest bedroom or bath. A home expansion may involve reworking layout, extending square footage, or combining multiple new rooms for a more integrated flow.

Do you handle permits?

Yes. Our in-house architect and structural engineer manage the full permitting process. We’re fully licensed and well-versed in California’s building codes, so you can relax knowing every detail of your home addition is handled professionally.

Can you match the new addition to the existing style of my home?

Absolutely. Seamless integration is a core part of our design-build approach. We match finishes, rooflines, architectural details, and flow, so your addition looks and feels like it’s always been there.

Will I need to move out during the addition project?

Not always. Many clients stay in place during construction, especially for garage conversions or detached additions. We’ll talk you through what to expect and help make it as comfortable as possible.
