Interiors that could only be yours
We work with your story to craft a narrative and a vision for how you want to live, then bring it to life in timeless, quietly elegant rooms.
As seen in
The Scale Collective is a boutique interior design studio creating some of the most collectible interiors in California and beyond: relaxed, modern living with timeless European elegance, that could only be yours.
Our method
A home designed
like a story
A home is built before it is furnished, and we design it the same way. First your story, then the architecture of the space, its light and proportion, and finally the pieces that bring it to life, each chosen for its scale and form.
I
Your story
We listen first: how you live, what you collect, how you want to feel when you walk in the door.
II
The narrative
We write it into a concept: a palette, a mood and a few defining pieces that every decision answers to.
III
Scale & architecture
We design the architecture before a single chair: walls, ceilings, light and built-in millwork, so the space fits the story.
IV
The collection
We layer in furniture, artisans and art, often commissioned for you, until the home feels collected, never bought.
The film
Golden hour in the Beverly Hills penthouse
A 2,600-square-foot home on the 39th floor of a Beverly Hills tower, designed for a young entrepreneur new to Los Angeles. We let the cloud-level light set the story: warm neutrals in shearling, bouclé, mohair, oak and walnut, low furniture that keeps the view open, and art as the only real color in the room.

The style
Organic modern, warm at heart
Our style is organic modern: the clean lines of modern design, softened by natural materials, sculptural forms and art, then layered until a room feels warm and lived in. Some call it warm minimalism. Calm the moment you walk in, never cold, and still right ten years later.
- Layered, never clutteredTexture and soft light, with room to breathe.
- Art makes the spaceEach room is built around one piece.
- Furniture as sculptureCollectible forms, chosen for scale.
- Materials that age wellPlaster, oak, stone, linen.
- European soulCalifornia light, old-world grace.

Meet Sara Alexander
Your story, our vision, one home.
Sara began the studio as Studio Sara Haag and renamed it The Scale Collective in 2023, because design is never done by one person, and scale is at the heart of her work. Trained in architecture, she starts with the bones of a room, its proportion, light and flow, before a single piece of furniture is chosen. That is the name, too: every piece is selected for its scale and sculptural presence in the space.
Today she leads a small team of designers from the studio in Tiburon, working with clients in Marin County, San Francisco and wherever their stories take them.

“The most successful projects start with a strong team, and that is why we love working with Sara and her team at The Scale Collective. The process is truly open and collaborative, and the end results are reflective of Sara’s commitment to design excellence. Her ideas are always original, thoughtful, and unique. Can’t wait for our next project together!”

One primary bedroom in a Tiburon waterfront home, from first plan to final rendering. Every room we design moves through the same four steps before a single piece is ordered.




Questions
Before you begin
What is organic modern interior design?
Organic modern interior design pairs the clean lines of modern architecture with natural materials, soft textures and sculptural, handmade forms. Often called warm minimalism, it is calm and uncluttered but layered and inviting rather than stark. Our version adds collected art and European grace, so each home stays timeless and personal.
What is the difference between interior design and interior architecture?
Interior design shapes what goes into a room: furniture, materials, color and art. Interior architecture shapes the room itself: layout, walls, ceilings, openings, lighting and built-ins. Because we're trained in architecture, we do both, working alongside your architect and contractor.
How much does an interior designer cost?
Like most high-end interior design studios, we work on an hourly fee, with a procurement fee on furniture, art and materials purchased through the studio. Every home is different, so we don't publish ranges. The first 30-minute Zoom call or local site visit is complimentary; a longer walk-through and design assessment is billed as an initial design assessment fee.
Can you help us choose or commission art?
Yes. Art consulting is part of every full-service project and is also available on its own. We arrange gallery visits, introduce you to artists and artisans, and commission custom pieces, from a single canvas to a large-scale mural.
Where do you work?
The studio is based in Tiburon and works throughout Marin County, San Francisco and the greater Bay Area, including Sonoma and Napa, with selected projects in Los Angeles and Miami.
