What to Expect Working With a Full-Service Interior Designer
Full-service is one of those phrases that sounds reassuring but rarely gets explained. You know it means the designer handles more — but more of what, exactly, and what does the experience actually feel like from your side of the table? If you’ve never worked with a designer this way, the unknown can make a wonderful process feel opaque.
So here is the honest, behind-the-scenes version: what a full-service engagement includes, the phases you’ll move through from first call to install day, what’s expected of you along the way, how long it takes, and how the money works. Knowing the shape of it makes the whole thing feel less like a leap and more like a well-lit path.
First, What “Full-Service” Actually Means
Full-service is the most complete way to work with a designer. Rather than advising on a few decisions, the designer authors the entire project and manages it end to end: space planning and selections, custom and trade-sourced furnishings, drawings and specifications, procurement and order tracking, contractor coordination where there’s construction, and the final install and styling. The defining difference from hourly or decorating help is that you hand over the logistics, not just the vision. You make the meaningful decisions; the studio carries everything else.
It’s the right fit for whole-home projects, renovations, new builds, and anyone who wants a cohesive, turn-key result without managing the moving parts themselves. (If you’re still deciding whether you need this level of service, our guide on how to choose an interior designer helps you match the model to your project.)
Phase 1 — Application, Consultation, and Onboarding
A good full-service relationship starts slowly and on purpose. At Sentenac House, every project begins with a short application and a generous conversation — a paid consult where we learn how you live, what the home needs to do, your investment range, and your timeline. If we’re a fit, onboarding follows: a signed agreement, a retainer, and a deeper questionnaire that turns “I like calm, warm rooms” into a working brief. This phase is where expectations get set, so nothing later comes as a surprise.
Phase 2 — Concept and Design Direction
Next, the studio translates your brief into a point of view. You’ll be presented with a concept: the overall direction, palettes, materials, moodboards, and the feeling each space is meant to hold. This is the moment to react honestly — to say what resonates and what doesn’t — because everything downstream builds on it. Expect to give feedback, not to art-direct. The designer’s job is to listen closely and then make confident calls; yours is to trust the direction once it’s right.
Phase 3 — Design Development and Specification
With the direction approved, the work gets technical and specific. This is where floor plans, elevations, lighting plans, and detailed selections come together — every finish, fixture, piece of furniture, fabric, and material specified and documented. On a renovation or new build, this is also where the designer coordinates with your contractor and trades so the construction is built to the design rather than guessed at. You’ll review and approve, but the heavy lifting — sourcing, drawing, specifying, pricing — happens behind the scenes.
Phase 4 — Procurement and Project Management
Once you approve the design, the studio orders everything and manages it to your door. This is the unglamorous, enormously valuable middle: placing orders through trade accounts, tracking lead times, coordinating freight, inspecting deliveries, handling the inevitable damaged or backordered item, and keeping construction and vendors on schedule. It’s also where full-service quietly earns its keep — the months of logistics you never have to touch. Expect regular updates rather than daily noise, and trust that “quiet” usually means “handled.”
Phase 5 — Installation and Styling
Then comes the part everyone pictures: install day. The studio receives, places, and styles everything — furniture set, art hung, rugs laid, beds made, the last accessories and greenery placed — often while you’re away, so you walk into a finished home rather than a construction zone. A proper full-service install is theatrical on purpose: the goal is for you to see the whole vision realized at once, complete and ready to live in.
What’s Expected of You
A full-service engagement is a partnership, and the best outcomes come from clients who lean into a few things. Be honest early — about budget, about what you love and don’t, about how you actually live. Be decisive when it’s time to approve a direction, and then trust it rather than re-litigating settled decisions, which is the single biggest cause of delays and added cost. Communicate through the agreed channels, fund the milestones on schedule, and let the studio absorb the logistics. Your job is to be a clear, engaged client; the studio’s job is everything else.
How Long It Takes
Plan in months, not weeks. A fully designed, furnished home — especially with custom pieces and construction — generally runs from several months to a year or more once lead times, fabrication, and install scheduling are factored in. Phasing can stretch the timeline gracefully; rushing it almost always shows. A good designer sequences the work so the home feels intentional at every stage rather than half-finished.
How the Fees Work
Full-service pricing usually blends a few models: a flat or per-square-foot design fee for the creative and management work, cost-plus or trade pricing on the furnishings the studio sources for you (in Arizona, full-service markups typically run around 15% to 25% over trade cost, never above retail), and a retainer up front with the balance billed against milestones. Our Arizona interior design cost guide breaks the numbers down in detail. At Sentenac House, projects begin at a $25,000 minimum investment, which reflects custom, commissioned work rather than catalog décor.
