At Sable & Brass,
there is only one option.
Perfection.
For those who have built an extraordinary life
and will not settle for an ordinary home.
For those who understand that true luxury
is not purchased — it is curated, with intention.
"We don't compete on price. We compete on outcomes. And our outcomes are incomparable."— Yohanna Mueller, Principal Designer
Every other design firm forces a compromise. Choose fast turnaround — sacrifice quality. Choose budget-friendly — sacrifice excellence. This is the triangle every client has been conditioned to accept.
We built Sable & Brass to obliterate that compromise. Our atelier operates at the precise intersection of flawless craftsmanship, curated trade relationships, and Yohanna's irreplaceable singular vision — delivering results that simply cannot be compared.
This is not a claim. It is a promise backed by fifteen years of incomparable work and a client retention rate of 100%.

Yohanna's design DNA is the result of years refining a singular aesthetic: the rare blend of Coastal ease, Transitional elegance, and Japandi restraint — expressed as something entirely her own.
Yohanna didn't just design our Pacific Heights home — she understood the life we wanted to live inside it. Every room is a perfect balance of calm and sophistication. We have hosted world-class guests who have been rendered speechless. Sable & Brass is in a category of one.
After staging our Noe Valley property with Yohanna, we received four offers over asking within the first weekend. Buyers didn't just want the house — they wanted the life she had created inside it. The ROI was extraordinary. She is simply in a league entirely her own.
Our rental property was performing averagely. Yohanna's team transformed it completely. Our new monthly rate is 32% higher and we're booked months in advance. The investment paid for itself inside a year. There are no words adequate for this level of talent and vision.
I have worked with designers in New York, London, and Milan. Yohanna Mueller is the only one who truly listened — who understood I didn't want a beautiful home, I wanted a sanctuary. She delivered something I didn't know was possible. I will never work with anyone else.
The consulting session alone was worth its weight in gold. In two hours, Yohanna resolved problems we had lived with for years — with such elegant simplicity. The hourly rate seems significant until you realize it eliminates months of costly mistakes. Utterly transformational.
Our whole-home makeover in Sea Cliff is the closest thing to perfection I have experienced in any domain of my life. Yohanna's aesthetic — that extraordinary blend of coastal serenity and Japandi restraint — is unlike anything you will find anywhere else. Forever grateful.
Born in Munich with a decade shaped by New York's most prestigious design houses, Yohanna Mueller arrived in San Francisco with a singular vision: to create interiors that do not merely look beautiful, but feel profoundly, unmistakably right.
Her signature aesthetic — Refined Organic Coastal Modern — weaves together the breezy calm of coastal living, the timeless balance of transitional architecture, and the meditative restraint of Japandi minimalism. The result: spaces that feel simultaneously deeply luxurious and immediately, organically at home.
Her creative lineage draws from Kelly Wearstler's sculptural warmth, Amber Lewis's textured coastal sophistication, Axel Vervoordt's museum-like serenity, Nate Berkus's layered elegance, and Vincent Van Duysen's architectural precision — all filtered through Yohanna's irreplaceable personal vision.
Yohanna's sensibility is informed by the masters of quiet luxury — then transcended into something entirely, unmistakably her own.
