What Interior Design Costs in Denver and Centennial (With Real Numbers)
The number one question I get from people who've never hired a designer before is some version of: "What does this actually cost?"
It's a fair question, and one the industry has historically been terrible at answering. Vague ranges, hidden markups, fee structures that require a translator. I've never understood why designers make this so opaque. Informed clients make better decisions, and better decisions make for better projects.
So here's a straight answer, with real numbers.
How designers charge: the main structures
There's no single standard in the industry. Most experienced designers use one of these approaches, or a combination.
Hourly. You pay for the designer's time; meetings, design development, sourcing, coordination. In the Denver metro, experienced residential designers typically charge $150–$350 per hour. This works well for consultations, single-room projects, and situations where scope is genuinely hard to predict upfront. The downside is that the total can be hard to forecast, which makes some clients anxious.
Flat project fee. A fixed fee for the full project or specific phases, based on scope and deliverables. In the Denver and Centennial area, flat fees for residential projects typically range from $15,000 to $100,000+. This gives you cost predictability for the design work itself and is most common for kitchens, bathrooms, full-home renovations, and new construction.
Percentage of project budget. The design fee is calculated as a percentage, typically 10–20%, of your total construction and/or furnishings budget. On a $300,000 renovation, that's $30,000–$60,000. This model scales naturally with project size and is most common on large custom homes and new construction.
Cost per square foot. Less common but sometimes used for new construction or full-home furnishing packages. Denver-area rates typically run $5–$15+ per square foot. A 3,000 square foot home at $10/sq ft is a $30,000 design fee.
Hybrid. The most common approach for full-service designers, and the one I use. Flat fees for clearly defined phases (concept development, space planning, specifications), hourly for more fluid phases (furniture and art sourcing, installation, styling). This gives clients cost certainty on the big decisions and flexibility where the work is harder to scope precisely upfront.
What's typically included in a design fee
This varies by designer, so always ask. Generally, a full-service design fee covers:
Initial consultation and site visit, design concept development, space planning and furniture layouts, material and finish selections (flooring, tile, countertops, cabinetry, fixtures, paint), lighting design, custom millwork specifications when applicable, coordination with your architect and contractor, and a specified number of site visits during construction.
What usually costs extra: procurement management (ordering, tracking, receiving furniture and materials; typically billed as a 20–30% markup on net cost, or hourly), delivery and installation coordination, custom furniture design and fabrication, art sourcing, and revisions beyond the agreed scope.
Always read the contract carefully on procurement. Some designers include it, some don't, and the markup structure varies significantly.
What to expect to spend in the Denver and Centennial market
These are honest ranges based on current market conditions, not best-case scenarios.
Kitchen renovation: Construction $75,000–$200,000+. Design fees $7,500–$30,000+. Furnishings and accessories, if applicable, $5,000–$25,000+.
Bathroom renovation: Construction $25,000–$75,000+. Design fees $3,000–$12,000+. Fixtures and accessories $5,000–$15,000+.
Full home renovation (2,500–3,500 sq ft): Construction $200,000–$500,000+. Design fees $30,000–$75,000+. Furnishings $75,000–$250,000+.
New construction custom home: Budget 10–15% of total project cost for design fees, and 10–20% of home value for furnishings and finishes.
Rule of thumb: 10–15% of your total project budget for design services is a reasonable planning figure.
A note on Colorado-specific factors
A few things push costs higher here than in some other markets.
Colorado's temperature swings and intense UV exposure mean materials need to be specified carefully, what works in a more temperate climate may fail or fade here faster than expected. That requires more attention at the specification stage.
The current tariff environment has introduced real unpredictability in material pricing. Things sourced internationally, which is most custom furniture and a significant portion of tile and stone, can shift in price between the time something is specified and when it arrives. Good planning and appropriate contingency budgets help absorb this, but it's worth knowing going in.
Lead times have also lengthened. Custom furniture that used to take 10–12 weeks now commonly runs 14–18. Stone and tile from overseas sources can take longer. This is another argument for starting the design process earlier than feels necessary; by the time your renovation is complete, you want furniture arriving, not still in a factory queue.
My pricing structure
I use a hybrid model: flat fees for well-defined phases, hourly for the more fluid ones.
Design consultation: $500, credited toward full-service if you move forward within 60 days.
Partial services (kitchen or bathroom design, space planning, material selections for specific phases): $8,000–$45,000.
Full-service design (concept through final installation): $35,000–$100,000+.
Every project gets a detailed proposal before anything is signed; scope, deliverables, timeline, and investment, in plain language. No surprises later.
Does hiring a designer save you money?
The honest answer is: sometimes, and not always in the way people expect.
The clearest financial argument is mistake prevention. A custom sofa ordered in the wrong size, tile that looked right in the showroom and wrong in the room, a lighting layout that requires expensive rework; these are real costs, and they happen frequently on self-managed projects. One significant mistake often costs more than a design fee.
Designers also have access to trade-only showrooms and wholesale pricing. The markup you pay on a designer's procurement is typically still lower than retail on the same or comparable pieces, and you're getting professional guidance on the selection.
The less quantifiable argument, but the one I'd make most strongly, is this: your time has value.
The hours spent researching tile options, coordinating contractor schedules, tracking furniture deliveries, and making hundreds of decisions without a framework for how they relate to each other add up fast. Most clients who try to manage it themselves either burn out halfway through or end up with something that never quite comes together because the decisions were made in isolation.
A good designer doesn't just save you money. They save you the version of the project where you've spent real money and still don't love what you ended up with.
Whether you need a designer
I believe you do if you're spending $100,000 or more on a renovation, building a custom home, working with an architect, doing anything involving custom millwork or structural changes, or simply feel overwhelmed by the number of decisions and don't have a clear framework for making them.
You may not need full-service if your project is cosmetic and limited in scope, or if you're genuinely experienced at space planning and material coordination. In that case, a consultation, two hours with a professional, in your home, focused on exactly what you need, might be exactly the right level of involvement.
If you're not sure, that's worth a conversation. I'd rather spend twenty minutes on a call helping you figure out the right level of service than have you commit to something that doesn't fit your project.
If you're planning a renovation or new build in Centennial, Castle Pines, Highlands Ranch, Littleton , or nearby areas and want to talk through what the investment might look like for your specific project, I'd love to hear about it.
