Our Process

Our Custom Home Building and Remodeling Process

At Brandywine Builders, we take the guesswork out of the custom building and remodeling experience. Whether you’re planning a custom home, a luxury remodel, or an ADU, our process is structured, transparent, and collaborative from beginning to end.

As a trusted Sonoma County home builder, we proudly serve clients also in Napa County and Marin County. With over 20 years of experience, we know how to navigate the details, from budgeting to the permit process to the final walkthrough.

Connected Design-Build Approach

Our goal is to make the entire custom home building and remodeling process smooth and enjoyable. We work with designers and builders to give you a connected design-build approach.

Our Building and Remodeling Process in Sonoma, Napa, and Marin Counties

Schedule a Consultation

We start with a conversation to learn about your goals, location, and timeline. Whether you’re from Sonoma County, Napa County, or Marin County, we want to talk to you. This sets the foundation for your relationship with us and for the rest of your project. We also learn whether or not you have plans, which will dictate the steps you take in our process.

Budgeting Work

Budgeting is a big part of building a custom home or remodel, and we work with you to make sure that your designer presents plans that align with your budget. Sometimes the budgeting process takes a few revisions, but when you work with our Northern California custom home building and remodeling company, you’re in safe hands. If you don’t have a design yet, then this budget is more preliminary.

Find an Architect or Designer

If you come to us with plans, you can skip signing the contract. If not, it’s time to find an architect who matches your goals. We can provide referrals and help you find the right design team for your project.

Finalize Budget with Permit Set of Plans

We also work with you to finalize your budget with the permit set of plans. Sometimes the plans will not align with your budget, and we can help you work with your architect to make those elements match.

Sign the Contract

Once the scope and budget are finalized, we move into a clear, detailed contract. We also lock into our building calendar and begin the next steps. Our ability to work hand-in-hand with your designer and architect gives you the design-build experience.

Begin Construction

Our team manages the entire building or remodeling process with clear communication and expert craftsmanship. We keep the jobsite clean, organized, and on time. Building and remodeling are not short timelines, but we keep you informed the entire time.

If you come to us without plans, we will begin construction as soon as permits as the design is finished and permits are issued for that design.

Finalize Selections

As construction progresses, we help you finalize your product selections like finishes, fixtures, and flooring. Whether you’re doing a mid-century modern remodel or building new, we keep your style and budget in mind.

Final Walkthrough and Warranty

We do a full walkthrough together to ensure every detail meets your expectations. Brandywine Builders provides a home building warranty in line with the National Association of Home Builders, and we’re always available for post-project support.
