Welcome to Brandywine Builders. We are a custom home builder serving Sonoma, Napa, and Marin Counties, helping homeowners navigate one of life’s biggest investments with thoughtful planning, clear communication, and quality craftsmanship.

We believe building or remodeling a home should be a collaborative and well-guided experience. Our role is to help align your vision, your priorities, and your budget while managing the many details that go into a successful project.

Whether you are building a custom home, remodeling your existing space, or adding an ADU, we serve as a trusted guide throughout the process, helping turn your ideas into a well-built home designed to last.

Every project is unique, and we approach each one with careful attention to detail and a commitment to doing things the right way. Our goal is to create spaces that feel personal, functional, and built to be enjoyed for years to come.
