A4 Homes Founder, Chris Adams, Awarded Leaders in Pro Builder's 2023 Forty Under 40

Recognizing and celebrating our 2023 Forty Under 40 class of energetic, innovative young leaders representing the future of the housing industry

“Chris truly has a passion for building custom homes. He started in the construction industry over 20 years ago pushing a broom and worked his way up the ranks from there. He was encouraged to obtain his contractor’s license by multiple architects four years ago and is now building luxury custom homes in the communities of Atherton, Menlo Park, Palo Alto, and Portola Valley in California. His down-to-earth demeanor brings an element to the build process that is one of a kind.” —Kate Adams, co-owner and office manager, A4 Homes

“Adams explains that what sets A4 Homes apart from other custom builders in the Bay Area isn’t any rigid, one-size-fits-all business model, but instead, the same flexibility and openness that got him started in the industry. He’s still actively seeking out mentors, learning new approaches to old practices, and, as always, keeping his connections close.” - Layne Dekens, Custom Builder 2023

“As an interior designer I very much enjoyed working with A4 Homes on a recent high end residential project. I found them to be organized and very prompt with communication. They had great rapport with their subs, strong relationships with inspectors, and it was always a clean job site with lots of activity and momentum, to keep on schedule. If there were any questions from the field on design details they always consulted prior to assuming and installing. The finished product was a beautiful home that was very well constructed and the client was thrilled with the results. I would highly recommend Chris and his team.”

— Stephanie Zaharias, Zaharias Design
“Chris Adams excels at communicating with Homeowners, Designers and Subcontractors to help projects meet schedules, budgets and attain a high level of finish. Chris is a team-player with an easy approach and a strong attention to detail.”

— Chris Kummerer, CKA Architects
"Chris Adams, who owns A4 Homes, is a trustworthy and accomplished contractor. He built my best client's, Jeff Wise’s, home in Atherton and received high marks. Chris recently finished a major remodel in Los Altos Hills to fantastic reviews from the owners, who are challenging and critical. If your clients are interviewing contractors, and reach to Chris, he will meet and exceed your and your client's expectations. “

-Rich Basin
"Our family is living in our dream home thanks to the team at A4 homes. Chris and his team are great to work with and the pride they take in their work shines through in their attention to detail and the finished project. Building a home is an intensive process with many decisions to be made. The positive attitudes of the A4 team, combined with years of experience and a willingness to problem solve and deliver our vision made the process worthwhile. We have a beautiful home that we are extremely proud of and we are grateful to A4 for working with us and putting our family first."

Calin Thomas, Portola Valley Custom Home Owner
" Honest, diligent, focussed, easy to work with, and detail oriented. Those are the qualities we were looking for when we searched for a general contractor to construct our most recent home. We found those qualities in Chris Adams and A4 Homes. Chris and his team built our amazing house on time and to the exacting specifications we had developed with our architect. He was organized and structured in getting the subs scheduled so the work could proceed most efficiently. He held them to the high quality standards that were required and maximized their performance. We have lived in this house for 3 years now and love it more all the time. Whenever there has been an issue with the house, Chris has been quick to respond and cheerfully gotten things fixed quickly. Over the years we have built 11 houses using 5 different contractors. We would rank Chris the best we have worked with and will use him for the next house we build. That’s the highest recommendation we can give!"

Jeff and Katherine Wise, Atherton Traditional Estate Owner
"You REALLY did put your blood, sweat and tears into our home and it shows and we love and appreciate it."
