About Jeffrey R. Rexford,
Principal Designer

Jeffrey R. Rexford began his career with a high school design/build project—a cabin for his teacher that still stands today. Fifty years later, he's still designing and building. A former licensed general contractor and VP of a Bay Area design-build firm, he is a graduate of Antioch College and holds a Bachelor of Arts in Art and Engineering.

Jeffrey’s expertise in design/build projects ensures beautiful, functional results within budget. “Design/build eliminates costly surprises—establishing the budget early and carrying it through to construction.”

Jeffrey is known for solving problems and guiding clients from concept to completion. His clients enjoy seeing their designs in 3D, knowing that Jeffrey will be with them every step of the way.

When he's not immersed in his design work, Jeffrey enjoys living in Sonoma County with his wife, cat, and a host of wildlife. A black belt in Kung Fu, he’s also passionate about photography and is a voracious reader, especially of murder mysteries and science fiction.

He really knows what he's doing and his skill set is top-notch. Being an artist myself, I felt an immediate connection with him. He has the imagination to find solutions that we couldn’t envision. He has the advantage of also having been a builder. Another BIG plus for us is that he's such a nice, easy-going guy. We truly couldn't be more pleased with Rexford Design.

TESTIMONIALS

  • "We made the right choice..."

    After interviewing several candidates, we decided to work with Jeff Rexford of Rexford Design. In addition to Jeff's four decades of design and build experience, we went with Jeff because of his ability to clearly articulate the process, management of our expectations, and listening skills which were demonstrated by the designs he presented after we discussed our vision.

    His 3-D virtual renderings made us certain that we made the right choice. Putting one's trust and money into someone is not an easy task. With Jeff, you can feel confident that you've made the right choice, we definitely are.

  • "His design sense is impeccable..."

    Jeff Rexford’s design sense and style are impeccable. I added a primary suite & bath with a walk in closet, custom cabinets, huge picture window in the bedroom, vaulted ceiling, and much more. Besides taking into consideration the cottage style of the existing home, he listened to what I wanted. I found it imperative that he paid attention to all my ideas incorporating them into a masterful design. In my new suite feel like I’m in a five star hotel.

    I live in a community that is known for design plans not passing through the town’s application process with at least one revision....but not with Jeff's plans: they went through the first time…unheard of!

    I can recommend Rexford Design with the utmost confidence.

  • "I can absolutely recommend him..."

    I was referred to Jeff through my general contractor and couldn't be happier with the service I received. We had a vague idea of what we wanted, and Jeff not only came up with a number of options, but were able to refine it to exactly what we were looking for! Jeff also liaised with other key stakeholders (HOA, engineers, contractor) to ensure that everything remained on track. I can absolutely recommend him if you're looking for design services for a project.

    Jeffrey has been great to work with! He is professional and prompt. Very honest and worked diligently to make me happy with my project. He has a system that’s flawless! I had a half put together makeshift idea on what I wanted and he made it all a reality!! I’m extremely happy with him and his work I would definitely give him an A++.

  • Jeffrey’s design exceeded our goals and we felt he took great care in listening to our needs.

    Jeffrey was the Designer for a 450 square foot Accessory Dwelling Unit on our property in Berkeley CA. The ADU was designed to complement the architecture of the existing house, while providing a handsome contemporary interior. Jeffrey’s design exceeded our goals and we felt he took great care in listening to our needs. Jeffrey was available for Project Supervision during the construction phase. We recommend Jeffrey for any design project.

    We'd Love To Work With Jeff!

  • I will happily recommend his design services

    Rexford Design, of course Jeffrey Rexford, was wonderful and easy to work with. I turned my home which I have lived in for almost 40 years into the home of my dreams and needs. I could never have envisioned the end result when I started this project. I will happily recommend his design services to friends embarking on the same remodel journey.
