Home Additions in Santa Rosa, CA

Even if you built your dream home 10 years ago, there’s no guarantee it won’t feel too cramped today. Our lives change, and sometimes this means adding onto a home we love to support the need for more room—like the birth of a child or housing an elderly parent. If the time has come to kick out the walls or add a little extra space, look at our expertise at ABA Custom Homes Inc for guest homes and other home additions in Santa Rosa, Roseland, Sebastopol, and Sonoma County, CA.


We can extend virtually any space directly off of your existing home or create room additions in a way that matches the aesthetic and style. From adding an extension to your kitchen to building on a home office to adding a laundry room. We carefully integrate every new addition into your home, so it feels like it was always part of the original plan.

We have experience constructing rooms of all sizes. From a few dozen square feet like a new laundry room to huge extensions that add a third of your home’s footprint, such as for a mother-in-law suite. Our abilities ensure you get the extra space you need. We can make your VISION A REALITY!
