The Design & Building Works
Great Homes Don’t Just Happen.
They’re Designed.
Practical, Beautiful Residential Design for Santa Rosa Homeowners
Let’s be honest—starting a home project can feel overwhelming. You have a vision, whether it’s a brand-new custom home, a rental unit in the backyard (an ADU), or finally tackling that long-overdue remodel. But turning that vision into a reality? That’s a whole other story. There are permits, building codes, contractors… it’s a lot.
That’s where we come in. At The Design & Building Works, we’re not just designers; we’re your guide through the entire pre-construction maze. We’re a Santa Rosa-based residential design firm that’s been helping homeowners like you get their projects off the ground since 1992.
Our founder, Ellen Picard, actually has an architecture degree from France. It gives her a unique eye for design and detail. But here in the U.S., she’s not a licensed architect, and that’s good news for you. It means you get all the design expertise and creative problem-solving of an architect, but without the hefty price tag. We’re the practical, cost-effective choice for residential projects.
ADU Design
They differ in sizes (from 220sf to 1200 sf) but always have a kitchen, bath & place to sleep.

We Handle the Headaches, So You Don’t Have To
Here’s a little secret about construction: the success of your project is decided long before the first nail is hammered. It’s all in the planning. A great set of drawings makes everything smoother—from getting accurate bids from contractors to passing inspections.
With three decades of experience right here in Sonoma County, we know the local codes and what the permit office wants to see. We handle all the detailed drawings and paperwork, so you can focus on the exciting parts of your project. We’ve learned what it takes to get a project approved and built successfully.
“A contractor in town told me, ‘If you want absolute professionalism with the highest quality and creativity, call Ellen Picard.’ She is responsive, pleasant, honest and helped us accomplish a 9-month project in 6 months. Truly an amazing experience. I would hire her again in a heartbeat!”
