About The Firm

  • ballonSTUDIO is a boutique luxury residential interior design firm based in San Francisco, founded by Sabra Ballon in 2003. We design private residences, estate properties often for multigenerational families, and boutique hospitality projects across the Bay Area, Marin, Tahoe, and Napa Valley and Sonoma.

  • Sabra Ballon is the founder and Design Principal of ballonSTUDIO. She holds a Master of Architecture from UC Berkeley and a design degree from UCLA, with more than 25 years designing homes for families whose properties carry real complexity: multiple residences, multiple generations, and long time horizons. That work has been rooted here throughout. Born and raised in Palo Alto, she has practiced in San Francisco for more than two decades and has known the city through several iterations.

    Her architectural training shapes both the design and the discipline: how a room is structured and proportioned, and how the studio holds budgets, timelines, drawing sets, and teams. She speaks the language of the architects and builders on the project, which makes collaboration direct from the first meeting.

  • We are a boutique firm with a team of senior interior designers who are also architects. Every project is led by experienced practitioners rather than passed down to junior staff, and our extended network of consultants, makers, and trade partners functions as part of that senior team. Clients tend to find us when a home is not a decorating project but part of a larger, longer story: a family growing into a property, a household running across several residences, a house meant to hold the next thirty years.

  • It is intentionally small, so that senior people do the work and nothing important is delegated away. Our depth comes from a network of specialist consultants, workrooms, and craftspeople built over two decades and assembled specifically for each project.

  • In June 2026, we just moved into our new office space.

  • Most of our work is in San Francisco and the greater Bay Area, Marin, Tahoe, and Napa Valley and Sonoma. We also work beyond Northern California when a project or an existing client relationship calls for it.

Services and Scope

  • We provide interior design for full scope residential projects: space planning, architectural detailing, finish and material specification, custom furniture design, furnishing, art placement, and installation. We hold the interior scope from early concept through the day the house is ready to live in, with the beds made and the pantry stocked.

  • Interior architecture shapes the permanent elements of a home: walls, openings, millwork, stairs, lighting, stone, and the details that hold a space together. Interior design addresses everything that furnishes and finishes those spaces. Because of Sabra's architectural training, ballonSTUDIO can work fluently in both, which is why we are most valuable when brought in early.

  • Yes. We work on ground up construction alongside the architect and contractor, on substantial renovations of significant homes, and on the refurnishing of houses a family already loves. The common thread is scope that rewards senior attention and architectural fluency.

  • Yes. Many of our projects include furniture, millwork, and fixtures designed by the studio and built by workrooms we have trusted for years. We also source vintage, antique, and contemporary pieces where they serve the room better than something made new, and we are comfortable designing around pieces a family already owns.

  • We take on select boutique hospitality projects where the sensibility is residential: small hotels, inns, and gathering spaces that should feel like well made homes rather than commercial interiors.

  • Occasionally, usually for existing clients or as the first chapter of a larger project. Our practice is built around full scope work, and we are candid when a project is not the right fit for how we work

  • Rarely as a standalone engagement. A single room is sometimes the right starting point within a longer relationship, and we are happy to discuss whether that applies to your situation.

Process and Timeline

  • Every project moves through discovery, concept, design development, documentation, procurement, and installation. Discovery is the part clients remember: we spend real time understanding how the household lives, entertains, works, and rests before a single material is proposed. From there, we structure decisions so they are made once, at the right moment, by the right people. Our full process is described on our approach page.

  • A substantial renovation or new build typically runs two to four years from first conversation to installation, driven largely by construction. Furnishing focused projects move faster. We give honest timelines at the outset and protect them by sequencing decisions carefully rather than rushing them.

  • As early as possible, ideally while the architect is still shaping plans. Early involvement lets interior thinking inform the building itself: where the light falls, how a kitchen actually serves a holiday, where the millwork wants to go. That saves cost and avoids rework later. If your project is already underway, we know how to join a team midstream.

  • As involved as they want to be. Some clients sit with us through every material selection; others delegate to an estate manager, owners' representative, or family office and join only for the decisions that matter to them. We design the decision structure around how your household actually operates, not the other way around.

  • In structured, decision oriented meetings with physical materials wherever possible: samples you can hold, finishes in real light, drawings at a scale that makes the choice legible. We prepare so that each meeting resolves specific questions rather than opening new ones.

  • We manage ordering, tracking, receiving, inspection, and installation through established logistics partners. Installation is planned as its own project phase, and the home is complete when you walk in, down to the last drawer.

  • We remain available. Homes evolve, families grow, and many clients return to us for subsequent properties or later chapters of the same house. Continuity is part of what we offer.

Cost and Investment

  • It depends on scope, scale, and the level of custom work, so we do not publish a single number. What we can promise is a clear fee structure, a realistic budget conversation at the very beginning, and no surprises after that. Cost clarity early is one of the ways we protect the relationship.

  • Fees are proposed after we understand the scope, and the structure is set out plainly in our agreement before work begins. We are happy to walk you, or your advisors, through it in detail during an initial conversation.

  • We build the budget with you at the start, covering design fees, construction related interior costs, furnishings, and installation, and we report against it throughout. Advisors and family office teams receive the documentation they need in the format they need it

  • We evaluate fit by complexity and scope rather than a strict minimum. [If the studio wishes to state a minimum engagement or budget threshold, it belongs here.]

  • Design fees, construction costs, and furnishing budgets are tracked separately and reported transparently. You always know what is being spent, where, and why.
