Our Principals

Julia Campbell and Buzz Tenenbom
Julia Campbell and Buzz Tenenbom started their unique collaboration of art and pragmatism, CTA Design Builders Inc., in 1991. Since its inception, they have achieved success in creating living spaces that are functional, beautiful and a joy to inhabit!

Julia Campbell, AIA, earned her Bachelors Degree in Interior Design from the University of Manitoba and her Masters in Architecture from the Massachusetts Institute of Technology. She has designed buildings and interior spaces for residential clients since 1981 and has shown her own art work in galleries and exhibitions throughout the USA and Canada. Julia's architectural design work is noted for its strategic use of space and inventive use of color, materials and detail to create a mood you will want to live with every day.

Buzz Tenenbom, AIA, a Washington architect and general contractor since 1981, has researched, published and taught on the subject of the symbiotic relationship between buildings and the environment. Buzz is your liaison and project manager, individually shepherding your project through the entire design and build process. His design skills and architectural background provide you with an understanding of the critical importance of the aesthetics of your project. His hands-on experience as a contractor and builder assures you of intelligent and resourceful use of your time and money.

As northwest architects and general contractors, Julia & Buzz both appreciate all the specialness of this place, and they strive to incorporate that esthetic with their work.
