Semmes & Co. Builders, Inc. was founded in 1978 by Turko Semmes as a small construction company focused on building passive solar homes. By bringing together local craftsmen with the most current construction technologies, he began building the Central Coast’s most unique and energy efficient projects.

We have grown into a family of over 15 employees, each of whom is dedicated to the highest quality craftsmanship, a service oriented building process, and the most sustainable building practices. We have completed over 300 custom homes and remodels, several homes for spec, and numerous select commercial projects such as small wineries, a medium sized private school, and an energy efficient shopping center.

Semmes & Co. has enjoyed watching our employees expand their skills and abilities over the years. We plan to continue growing and providing an even higher level of quality, while expanding our knowledge and commitment to green building.
