Sonoma County Interior Design
Decision overwhelm. Purchasing chaos. Construction stress. A renovation can quietly take over your life.
You want a space where hosting feels effortless, rest actually happens, and connections deepen naturally.
Our clear process brings design, purchasing, and construction coordination under one roof to guide you there.
The Hard Part Was Never The Vision
You already know how you want to live. What stalls most homes is everything in between: sourcing, trades, budgets, timelines, and the hundred small calls that all have to be right.
The real hard part is the handoff. On most projects, the designer draws it, and the builder builds it - and the gap between them is where the budgets slip, timelines stretch, and the vision quietly erodes.
It is why people often come to us wanting a clear process and a steady hand more than another mood board. An editor to tie all the threads together.
One Studio, Start to Finish
We do not hand over drawings and wish you luck.
We design the home, source and purchase every piece, and coordinate with the builder, trades, and vendors through to installation, running as a single process under AVCO Design so nothing falls through the cracks.
You make the decisions that matter and stay out of the ones that drain you.
The Certainty You’re Paying For
A written update lands in your inbox at the end of every week, so you always know exactly where the project and your investment stand.
Nothing is ordered without your written approval, and every proposal is priced room by room. No surprises, no quiet overruns, no decisions made without you.

What Clients Are Saying
“I've been working with Stephanie on a whole-house renovation . . . She's given me basically a new house in terms of modernizing and freshening up every room while retaining its character. But the best part about working with her is that she's delightful and easy to work with.”
Ann Peters, Kenwood, CA
“I can’t say enough about what a wonderful experience we had. Stephanie immediately understood my taste and priorities. I wanted someone to oversee the project and hire the contractor and subs, and AVCO did that. I never had to worry about anything. They are great communicators, professional, and easy to work with. It couldn’t have gone more smoothly.”
PAM WILSEY, SANTA ROSA, CA
“Stephanie of AVCO Design was a dream to work with! She immediately came up with a layout and furniture plan that worked for us, sourced many of the pieces, and had helpful advice on where we could save vs. which items to invest in. She really "got" our style and found several incredible pieces that give the space a lively charm we just adore.”
CAREY JONES, HEALDSBURG, CA

The Home And The Life In It
Picture the first dinner you host once it is finally done. The house works, the rooms feel like you, and for once, you are not thinking about the project at all.
That is what we build toward. Tell us about your home, and we will show you how we would get there.
