Owned and operated by Sonoma County native Mike Flowers, Oak Shadows has been building homes in Northern California since 1985. For the past 15 years, we have focused primarily on building high-end homes and estates, barns and wineries in Sonoma and Mendocino Counties.We work with property owners to build new homes or re-build existing ones. We also purchase raw land on which to design site-specific custom homes or homes on speculation.
