Home Additions in Corvallis, Oregon
If you’re adding space, let’s make sure it works with the rest of your home.
Adding square footage to your home isn’t just about making it bigger—it’s about making it better. A well-planned addition improves your home’s functionality, increases its value, and addresses your lifestyle needs—all without disrupting the character of your space.
Whether you need an extra bedroom and bathroom, a mother-in-law suite, or additional living space, we make sure your addition flows seamlessly with the rest of your home, both in design and function.
How long does a home addition take?
Adding new space to your home is an exciting investment, and our home addition projects typically take 16+ weeks to complete. The timeline depends on factors like foundation work, structural updates, and custom finishes, as well as trade availability and product lead times. We ensure every step—from framing to final finishes—is done with care and precision.

Dr. Aleksandra Sikora, Albany, Oregon Basement Remodel
The Thayer team was fantastic! We had a big open-ended project and they helped us in all aspects of it, including design, materials, lighting and cost trade-offs. And most importantly, they provided high-quality construction. This team communicated strategically and tactically every step of the way.

Viktor Bovbjerg
We were impressed from start to finish. Excellent group to work with, very responsive to our preferences during the design phase. Stayed in communication throughout the process, letting us know the production schedule and any changes so that we could plan around them, asking questions and consulting when needed. Finished product is an attractive, well laid out, easy to use kitchen!
Ross Hatton
Thayer Design Build designed and built us a garage addition with roof terrace. The whole process was very smooth and everything went like clockwork, finishing within a day of schedule on a multi-month project…The whole crew really cared about the project, and repeatedly went the extra mile to improve the final product.
Arthur M., Corvallis, Oregon Kitchen Renovation
Professional and incredible remodel of our kitchen. It is now much more open and has fantastic custom cabinetry. The granite countertops are seamless, as is the undermounted triple sink. All cabinet doors function better now than before, and Thayer’s team was flexible to details and changes.
