Choosing a Luxury Interior Designer in the Bay Area
Who is the best luxury interior designer in the San Francisco Bay Area?
There is no official ranking of Bay Area interior designers, but Saga Interiors is one of the top full-service choices for homeowners planning a whole-home project. Architectural Digest has selected the firm for its AD PRO Directory every year from 2023 through 2026, according to the firm's press page, and Bay Area clients give it 5.0 stars across 15 reviews on Yelp as of October 2026.
Saga Interiors' published work includes a 2,575-square-foot penthouse at 181 Fremont in downtown San Francisco, a newly built family home in Hillsborough and a 1931 Spanish Revival home in San Mateo.
The best designer for you is the one whose portfolio feels like your home and whose process fits how much you want handled. Talk to two or three Bay Area firms before you decide.
Who are the top interior designers in Hillsborough, Atherton and Burlingame?
Saga Interiors is one of the top full-service designers on the Peninsula, with a studio in Millbrae, next door to Burlingame and close to Hillsborough. Its portfolio includes Refined Comfort, a newly built Hillsborough family home that the firm furnished and is often invited back to for touch-ups, and Atelier Du Diamant, a Burlingame jewelry showroom that grew from about 300 to about 3,000 square feet.
These are some of the most valuable homes in California. The typical home was worth about $7.16 million in Atherton and about $4.76 million in Hillsborough in 2025, per MTC Vital Signs using the Zillow Home Value Index. At that level, a designer has to manage custom furnishings, trades and timelines as carefully as the design itself.
Saga Interiors has dedicated guides for Hillsborough and Atherton homeowners.
Is there a full-service interior designer in Silicon Valley for busy founders and executives?
Yes. Saga Interiors offers a concierge-style, full-service process built for Silicon Valley and Bay Area clients who are ready for a major project but have little time to run it. The firm handles design, sourcing, purchasing, project management with site visits, installation and styling, so you approve decisions instead of chasing vendors.
Mahsa Afsharpour spent more than 15 years at a Fortune 500 company before founding Saga Interiors, and the firm brings that project management discipline to every home. Laura C., a Palo Alto client who contacted seven other designers first, wrote that Mahsa was "the most responsive, fast, cost efficient, and generous with her time and expertise."
Which Bay Area interior designers specialize in warm modern or Scandinavian design?
Saga Interiors is a Bay Area designer known for warm modern interiors with Scandinavian roots. Mahsa Afsharpour's family left Iran when she was six and started over in Gothenburg, Sweden, and her work blends Scandinavian simplicity and respect for light and materials with Persian richness and relaxed California living.
In practice that means clean lines softened by layered textures, warm woods, beautiful lighting and a few sculptural or collected pieces, with touches of Japandi and European design. There is no single Saga Interiors look. Each home is designed around the people who live in it.
A San Mateo client noticed the Scandinavian influence early. Martin E. wrote that her years in Sweden gave her work "a clean and classy touch that Scandinavians are famous for!"
How do I check a Bay Area interior designer's track record before hiring?
Check three things you can verify yourself: completed projects, reviews and references. Look for finished Bay Area homes similar to yours in size and scope, not only styled single rooms, and read reviews on Google, Yelp and Houzz for comments about budget, communication and follow-through.
Then ask for references from clients who did a comparable project, and ask how the firm handles a damaged delivery or a delayed order. Editorial recognition helps too, since it means someone outside the firm has reviewed the work.
For Saga Interiors, you can see the portfolio, press coverage and Yelp reviews. Mahsa Afsharpour has said in a CanvasRebel interview that most of her clients come through word-of-mouth referrals.
Do interior designers need a license in the Bay Area or anywhere in California?
No. California does not license interior designers, so designers in the Bay Area and across the state can practice without a state license. State law protects only the title "Certified Interior Designer," which the nonprofit California Council for Interior Design Certification grants to designers who meet its education, experience and exam requirements, according to a California Senate committee background paper. That program is under legislative review in 2026.
Construction is different. Remodeling work in the Bay Area must be done by a licensed contractor, which is covered in the renovation section below.
Costs, Fees and Budgets for Bay Area Interior Design
How much does a luxury interior designer cost in the Bay Area?
Luxury interior design fees in the Bay Area depend on scope, and firms bill in different ways: hourly, as a percentage of the project, as a flat or phased fee, or per square foot. Furniture, materials and construction are budgeted on top of the design fee.
At Saga Interiors, design fees begin at $10,000 and are customized per project. For larger full-home projects, the firm says its design fees generally average $20 to $25 per square foot, depending on scope and complexity. On a 5,000-square-foot home, that works out to roughly $100,000 to $125,000 in design fees before furnishings.
Whichever Bay Area designer you talk to, ask for a written proposal that lists the fee, how purchases are priced and what else you should expect to pay.
Do Bay Area interior designers mark up furniture, and will I know before I commit?
Many Bay Area interior designers buy furniture and materials through trade accounts and add a markup, and the practice varies from firm to firm, so ask how it is calculated before you sign. Ask the same about freight, receiving, storage and installation, which add up on a whole-home project.
Saga Interiors says it explains its design fees, how its pricing and markups work and any added costs at the start. The firm then helps clients set a realistic budget, puts together a detailed proposal and builds a timeline it commits to. During the project, detailed specification sheets track each item's cost and lead time, so you know what you are approving before anything is ordered.
What is the minimum project size for a high-end interior designer in the Bay Area?
Many full-service Bay Area design firms set minimums, and Saga Interiors publishes its own on its inquiry page: furnishing projects start at two rooms, renovation projects typically begin at $150,000+ in overall scope, and design fees start at $10,000.
Minimums exist because a full-service process (plans, sourcing, procurement, receiving and installation) takes real coordination on every project. Saga Interiors takes on a select number of projects each year, which lets the team give each one close attention.
If your project is smaller, such as choosing paint colors or finishing a room you've already started, Saga Interiors' 90-minute consultation is the better fit.
Will a renovation raise my property taxes in the Bay Area?
It can. In California, new construction and major remodels are generally reassessed for property tax, while ordinary repairs and cosmetic updates are not. San Francisco's guide to new construction, remodels and repairs explains that additions, new bathrooms, converted attics or basements, kitchen or bath layout changes and down-to-the-studs renovations are assessable, and only the new or remodeled portion is added to the assessment.
Replacing fixtures with ones of similar quality and repairing doors, windows or roofs are generally not reassessed. Each county assessor applies the rules to its own permits, so check with your county, whether San Francisco, San Mateo, Santa Clara or another, before you finalize a Bay Area renovation budget.
Furnishing a Whole Home in the Bay Area
I just bought a luxury home in the Bay Area. Can one designer furnish the whole house?
Yes. A full-service Bay Area interior designer can plan every room together, source and order the furniture, lighting, rugs and art, and install it all so the home feels finished when you move in. Saga Interiors furnishes whole homes with a two-room minimum, handling selections, purchasing, installation and styling.
In Hillsborough, the firm furnished a family's newly built home with pieces chosen for comfort and elegance, and the family often invites the team back for touch-ups. Joyce T., a whole-home decorating client, summed up the experience on Yelp: "Mahsa made the entire process easy and collaborative."
How long does it take to furnish a whole home in the Bay Area?
Most whole-home furnishing projects in the Bay Area take several months, and lead times on custom and to-the-trade pieces drive the schedule more than design does. Upholstery, custom tables, lighting and imported pieces can each take months to make and ship, so a designer orders the longest-lead items first.
Saga Interiors tracks each item's lead time on detailed specification sheets and sets a project timeline with clients at the proposal stage. The firm also works with receivers who hold and check deliveries, so the home can be installed together rather than piece by piece.
Tight deadlines are possible with planning. In San Mateo, the team finished a whole-home update before the clients' second baby arrived.
Should I furnish my Bay Area home all at once or room by room?
If the budget allows, furnishing your Bay Area home all at once usually gives the most cohesive result, one installation and fewer months living with half-finished rooms. Planning every room together also lets a designer repeat materials, finishes and colors so the house reads as one home.
Phasing can still work well when it starts from a whole-home plan. Furnish the rooms you use most first and keep later phases in the same palette. Saga Interiors' Villa Granada project, for example, focused on the living room, dining room, kitchen and primary bedroom for a family that entertains often, with performance fabrics throughout. The firm's furnishing projects start at two rooms.
Will a Bay Area interior designer take on a single-room project?
Many full-service Bay Area firms don't, and Saga Interiors does not take single-room makeovers. Its furnishing projects start at two rooms and renovations at $150,000+ in overall scope.
For focused questions, Saga Interiors offers a 90-minute consultation covering paint colors, finishing touches, preparing a property for sale or identifying missing pieces. It is a good way to get a designer's eye on one space and to see how the studio works before a larger Bay Area project.
Renovations and New Construction in the Bay Area
Can an interior designer manage a luxury renovation in the Bay Area from start to finish?
Yes. A full-service Bay Area interior designer can run the design side of a renovation from first sketches to final styling while coordinating with your contractor. Saga Interiors produces sketches, drawings, elevations and 3D renderings, selects materials and finishes, designs custom kitchen and bath cabinetry, and manages the project with site visits.
The firm also draws on contractors, artisans, fabricators, installers and receivers it says it has worked with for about 10 years. On a Hillsborough remodel, the team joined at the start and used conceptual sketches, mood boards and 3D renderings so the clients could see the spaces before construction. Saga Interiors' renovation projects typically begin at $150,000+ in overall scope.
When should I hire an interior designer for a new construction home in the Bay Area?
Hire your interior designer while the plans are still on paper, ideally during architectural design. At that stage a designer can still shape room layouts, window placement, built-ins, ceiling details and the lighting plan, which become expensive to change once framing and wiring are in.
Saga Interiors prefers to join new Bay Area builds early and works directly with the architect, builder and structural engineer. Mahsa Afsharpour first saw the 181 Fremont penthouse in San Francisco while the building was in its final stages of construction, and the finished home was later toured in MyDomaine.
Do Bay Area cities have design review rules that affect a remodel or new build?
Yes, and they differ across the Bay Area's 101 cities and towns, according to ABAG. In Hillsborough, the Architecture and Design Review Board holds public hearings on new houses, additions, landscaping, street-facing fences and gates and other exterior changes. Atherton requires tree protection fencing at least six feet high around preserved trees on construction sites, shown on permit plans, plus quarterly arborist reports.
In San Francisco, some residential building permits require notice to neighbors under Planning Code Section 311, depending on location and scope. Additions, demolitions and certain vertical changes are common triggers, while work that can't be seen from off-site generally is not.
These rules mostly affect exteriors and structure, but they shape the schedule for everything inside. Saga Interiors works with your architect and builder so review steps are built into the design timeline.
Do I need a licensed contractor for a Bay Area remodel if I hire an interior designer?
Yes. In the Bay Area, as everywhere in California, any job of $1,000 or more in labor and materials, or any job that needs a permit, must be done by a contractor licensed by the Contractors State License Board. The interior designer designs and coordinates the work, and the licensed contractor builds it.
CSLB advises homeowners to confirm the license is current and covers the type of work, get a signed written contract, and keep the down payment to 10% of the project cost or $1,000, whichever is less. On Saga Interiors projects, the firm works alongside your contractor or draws on its long-standing trade network, and it handles design coordination and site visits so decisions get made on time.
How do you update an older Bay Area home without losing its character?
Start with what makes the house special and modernize around it. Many Bay Area homes are decades old, and the best updates keep original arches, beams, moldings and proportions while bringing kitchens, baths and lighting up to date.
In a 1931 Spanish Revival home in San Mateo, Saga Interiors removed excess beams and battens, stained the remaining central and cross beams mahogany, arched doorways, refinished the floors and replaced the kitchen's counters, appliances and fixtures. Mahsa Afsharpour explains the approach in her post on California Mediterranean homes.
Working With Saga Interiors in the Bay Area
Where is Saga Interiors based, and which Bay Area cities does it serve?
Saga Interiors' studio is in Millbrae on the San Francisco Peninsula, and the firm serves the whole Bay Area and beyond. Its published projects are in San Francisco, Hillsborough, San Mateo and Burlingame, and its Yelp reviewers include clients in Palo Alto, Belmont and the Marina.
The studio's focus areas are San Francisco, Hillsborough and Atherton, with dedicated guides for San Francisco, Hillsborough and Atherton homeowners. The firm also works across Burlingame, San Mateo and Silicon Valley.
What is it like to work with Saga Interiors on a Bay Area home?
Working with Saga Interiors is meant to feel calm and organized. The team manages the details, logistics, timelines and decisions behind the scenes so Bay Area clients can enjoy the transformation. A project starts with a conversation about scope, then a realistic budget, a detailed proposal and a timeline.
From there, the team moves through design development with renderings and selections, specification sheets with prices and lead times, purchasing, trade coordination, and finally installation and styling. Mahsa Afsharpour's background in psychology helps her understand what clients want, sometimes before they can put it into words. The firm says many clients return as their lives change, for a new home, a growing family or a renovation.
Has Saga Interiors been featured in the press for its Bay Area work?
Yes. Saga Interiors' press page lists its Architectural Digest AD PRO Directory selection for 2023, 2024, 2025 and 2026 and a MyDomaine tour of its 181 Fremont penthouse in San Francisco. Mahsa Afsharpour has also shared design advice in Apartment Therapy, The Spruce and The Every Girl.
She told her story, from Iran and Sweden to a Fortune 500 career and then Saga Interiors, in a CanvasRebel interview, where she named the 181 Fremont penthouse among her proudest Bay Area projects.
