Structured Milestone Delivery
Our Commercial Design Process
Four phases. Permit acquisition is its own accountable milestone something superficial decorating studios consistently skip.

Space Feasibility & Photorealistic 3D Spatial Pre-Visualization
On-site laser measurements of structural columns, ceiling heights, and natural light then floor plans and 3D renderings so you see finishes before a wall moves.
Full Compliance Before You Break Ground
We prepare complete permit submittal sets and Title 24 compliance drawings, then submit them directly to City of Tustin plan-check — no third-party expediter, no waiting on someone else’s schedule to move your project forward.
Open-Book Pricing, Zero Dealer Markup
We source furniture and fixtures direct from manufacturers at open-book factory pricing instead of a dealer catalog markup. You see the same invoice we do, with real savings passed straight through to your budget.
One Team, On-Site Through the Finish Line
We coordinate every trade on-site, run punch-list inspections room by room, and manage the full operational handover Jeannice stays involved through final walkthrough, not just the design phase.
Execution Stage Within the Process
Commercial Design Build Contractor
Construction lives or dies on jobsite coordination. We work directly with licensed general contractors and master millworkers reviewing RFIs and resolving field conditions before they become change orders.
- Weekly Site Audits: Checking framing, electrical drops, and finish alignments.
- RFI & Submittal Clearance: Rapid response preventing jobsite stoppages.
- Final Punch-List Audit: Room-by-room inspection before move-in.

Frequently Asked Questions
Common questions about commercial interior design services in California
Real design work — furniture comes last, not first. We start every Tustin project with space planning and photorealistic 3D visualization before a single wall gets touched, then move through permits and construction as one connected process. If a firm shows you a catalog before they show you a floor plan, that’s a red flag worth asking about.
It depends on scope — a Tustin Legacy office fitout costs differently than an Old Town Tustin retail buildout. What we can tell you upfront: we source furniture direct from manufacturers at wholesale instead of a dealer catalog markup. We’ll walk your Tustin space and give you a real number before you commit to anything.
we’re not physically based in Tustin, but we serve it in person — on-site walkthroughs, direct contractor coordination, and City Hall meetings when needed. Proximity on a map matters less than what happens once we’re there. If you’re comparing firms, ask each one how often they’re actually walking your building in Tustin.
We handle it ourselves. Full CAD permit sets and Title 24 compliance drawings go directly through City of Tustin Community Development Department plan-check as part of our design-build process — not outsourced to a third party. That’s usually the part of a commercial project here that drags the longest when a firm doesn’t have direct experience with local plan-check standards.
When you hire a designer and a separate contractor, someone has to translate between the two — and that’s usually where Tustin projects go over budget. Our commercial design-build model keeps design, permitting, and construction under one accountable team, from CAD blueprints through final punch-list, with no finger-pointing between vendors.
It’s real — we’re not tied to any single manufacturer’s catalog, so we source commercial furniture at open-trade wholesale pricing instead of a dealer markup. For a Tustin project of any real size, that difference covers a meaningful chunk of your budget. Ask to see the wholesale invoice directly — we don’t hide that number.
It depends on scope, but yes — we’ve compressed timelines before, especially when a lease deadline isn’t negotiable. The fastest path is locking the 3D concept early and running City of Tustin permit processing and wholesale sourcing in parallel instead of one after the other. Call and tell us your real deadline; we’ll tell you honestly whether it’s realistic.
We built the studio around boutique commercial interior design on purpose — a small shop along El Camino Real gets the same direct attention as a larger corporate office project in Tustin Legacy, not leftover hours after bigger accounts. Shop interior design and small office projects go through the identical process, just scaled to the footprint.
You’ll deal directly with Jeannice Carrillo, the studio’s principal designer, from the first walkthrough of your Tustin property through the final punch-list. A lot of larger agencies hand you off to a junior coordinator once the contract’s signed — we built the studio specifically so that doesn’t happen here.
They overlap, but corporate interior design usually means office and workplace environments specifically — acoustic privacy, daylight, layouts built around how a team works. Commercial interior design is the broader umbrella that also covers retail and other business spaces. When someone in Tustin asks us about commercial interior design, we usually ask which one they mean first, since a Tustin Legacy office and an Old Town shop have very different priorities.
