Building for a

Welcome to
Kobban Builders

With an eye to the future, our work is built to last. Our customer relationships are for the long term. And we integrate earth friendly materials and energy efficiency into our standard approach. Our goal is to help you realize your remodel or building aspirations, have fun while you are at it, and love the end result.

Our specialty is helping you create expanded living space, whether that is a second story or other addition, or a backyard cottage or ADU (Accessory Dwelling Unit). We are passionate about creating the space you want to live or work in – or build out for additional income – and having you enjoy the remodeling experience. We care deeply about good craftsmanship, beautiful, livable spaces, and getting your project done on time and within your budget.

Remodeling can be very stressful, but we can honestly say that our experience with Kobban Builders went smoothly and often was even fun.

I was thrilled with the job Kobban Builders did on my house when I finally addressed about four years of deferred maintenance.

We're really happy with how Kobban Builders matched moldings and other details to make it look "right" in our 1912 Craftsman home. That is true artistry!

Kobban Builders was very reasonably priced and efficient and will be my first phone call when I need a contractor in the future.

Second story additions

Kobban Builders Additions Bay Area
Many Bay Area homeowners that want to “trade up” to a bigger space realize that not only is it often more cost effective to build on a second story (versus buying a larger home), but that it lets you design it exactly how you want it. We have helped dozens of homeowners grow their homes as their families grow and need more space. We partner with you, your architect and other team members to help you realize the future vision for the space that you create so many memories in.

ADUs (Accessory Dwelling Units)

Accessory dwelling unit

Some call them granny units, in-laws, or backyard cottages. Whether you want a space for your aging family member, an office, a guest cottage, art studio, or a separate rental unit, building an ADU can enhance your property value. Construction financing could potentially help get you there faster.

We can help you coordinate the right team of experts for your project – from an architect with ADU experience and an understanding of local permitting, to a structural engineer and even connect you to experienced ADU lenders.
