Nobody Wants to Tell You Real Numbers. I Will.
Ask most designers what interior design costs and you'll get a lot of careful hedging: "It depends on the scope," "Every project is different," "We'd love to discuss your specific needs." All of that is technically true. None of it helps a homeowner figure out whether to pick up the phone.
After 25 years of interior design in Scottsdale — from single-room refreshes to 8,000-square-foot custom home builds — I've developed strong opinions about budget transparency. Clients deserve real numbers. Here are mine.
This article covers designer fees, furniture and furnishing budgets, and the variables that push costs in either direction. By the end, you'll have enough information to build a realistic picture of what your project might cost — and whether the investment makes sense for where you are right now.
How Interior Designers Structure Their Fees
Before talking numbers, it's worth understanding the fee structures you'll encounter. There are three common models, and they're not equivalent — even when the end numbers are similar.
Hourly Rate
The designer charges for time spent on your project. In Scottsdale and the greater Phoenix metro, expect a range of $150 to $350 per hour for experienced, credentialed designers. Hourly works well for consulting-only engagements, smaller projects with clear scope, or clients who want to stay involved in every decision. The risk is that costs can escalate if the project expands or decisions take longer than anticipated.
Flat or Fixed Fee
The designer quotes a single fee for a defined scope of services. This is predictable for clients and requires the designer to scope very carefully — because overruns come out of their margin, not your budget. Flat fees work best when the scope is well-defined at the outset. A primary suite renovation with clear boundaries is a reasonable candidate. A "whole house, we'll figure it out as we go" project is not.
Percentage of Project Cost
The designer's fee is calculated as a percentage of the total project budget — including furniture, fixtures, and construction. Typical ranges run from 15% to 30% depending on the designer's experience level, the complexity of services, and the market. This model aligns the designer's incentive with project quality (more complex, higher-budget projects naturally generate more work), though clients sometimes worry it incentivizes spending. A good designer's incentive is your satisfaction and referral, not your budget size.
Design Fee Plus Trade Pricing
Many full-service designers — including Park Avenue Design — charge a design fee for professional services, then pass trade pricing through to clients at a markup that is typically still below retail. This means you pay less than the general public would for the same items, and the designer is compensated for their sourcing work. The math usually favors clients substantially when significant furnishings are involved.

Design Fee Ranges by Project Type
These are realistic ranges for full-service interior design in Scottsdale — meaning concept through installation, not consulting only.
Single Room Redesign
A living room, primary suite, or home office that stays within its current walls — no structural changes, new furniture, finishes, and styling.
- Design fee: $3,500 – $8,500
- Furniture and furnishing budget (not including the fee): $15,000 – $60,000+ depending on the room and quality level
Kitchen Renovation
New cabinetry, countertops, appliances, plumbing fixtures, lighting, flooring, and tile. Layout may or may not change.
- Design fee: $8,000 – $20,000
- Total project cost including construction and materials: $75,000 – $250,000+ in Scottsdale's custom residential market
Primary Suite + Bath
Bedroom and en suite bathroom together, often including closet. Plumbing, tile, cabinetry, fixtures, furniture, and window treatments.
- Design fee: $10,000 – $22,000
- Total project cost: $80,000 – $200,000 depending on bath size and finish level

- Total project cost (construction + furnishings): $300,000 – $1.5M+ for luxury Scottsdale homes
New Construction Interior Design
Working alongside an architect and builder from the framing stage through final styling. Includes all material selections, cabinetry, lighting plan, plumbing fixtures, and full furnishings package.
- Design fee: $50,000 – $150,000+ depending on square footage and complexity
- Total budget (not including construction): $500,000 – $2M+ for the interior finish and furnishings on a high-end custom home
Furnishing Budgets: What a Room Actually Costs to Furnish
The designer's fee is only part of the picture. Most of the money in an interior design project goes to furniture, fixtures, and materials — not to the designer. Here's what a quality room furnishing looks like at various budget levels.
Living Room / Great Room
- Entry-level trade quality: $25,000 – $45,000 (sectional or sofa grouping, coffee and side tables, lighting, window treatments, art and accessories)
- Mid-range luxury: $50,000 – $90,000 (custom upholstery, better case goods, significant lighting budget, curated art)
- High-end custom: $100,000 – $250,000+ (bespoke furniture, artisan sourcing, statement lighting, original art collection)
Primary Bedroom
- Entry-level trade quality: $15,000 – $30,000
- Mid-range luxury: $35,000 – $65,000
- High-end custom: $75,000 – $150,000+
Dining Room
- Entry-level trade quality: $12,000 – $25,000
- Mid-range luxury: $28,000 – $55,000
- High-end custom: $60,000 – $120,000+
What Drives Interior Design Costs Up
Within any of these ranges, specific factors push budgets higher. Understanding them helps you prioritize.
Custom Millwork and Built-Ins
Custom cabinetry is expensive — and worth it when the design calls for it. A built-in entertainment wall might run $15,000 – $45,000. A custom closet system, $12,000 – $30,000. These pieces are typically American-made, built to exact specifications, and meant to outlast the trends that will come and go around them.
Stone Selection
Stone is priced per square foot, but the range is enormous. A serviceable quartzite slab might run $15–$25 per square foot installed. A rare book-matched marble with complex veining could be $80–$150 per square foot or more. Slab selection matters — and in Arizona, where we use natural stone extensively in kitchens, bathrooms, and outdoor spaces, the choice has long-term implications for maintenance and durability.
Custom Upholstery
A custom sofa built to your dimensions, with your fabric selection, from a high-quality American frame: $4,000 – $12,000. A pair of custom club chairs: $3,000 – $8,000 each. Lead times are typically 12–16 weeks. The result fits your space exactly and will last decades rather than years.
Artisan and International Sourcing
Pieces sourced directly from artisan workshops — hand-blown glass from Murano, hand-knotted rugs from North Africa, ceramic work from European craftspeople — carry price premiums that reflect the time, skill, and material quality involved. A hand-knotted 9x12 rug: $8,000 – $40,000. A hand-blown art glass piece: $2,000 – $15,000. These are one-of-a-kind. They don't exist in a catalog.
Arizona-Specific Considerations
Desert climate imposes performance requirements that affect what we specify. Outdoor furniture must survive extreme UV and heat. Window treatments in western-exposure rooms need to be functional, not just decorative. Some materials that perform beautifully in coastal or northern climates simply don't belong in Phoenix-area homes. Specifying incorrectly costs more in replacements than the premium materials would have cost upfront.
What Drives Costs Down (Without Sacrificing Quality)
Contrary to what you might expect, working with a designer with significant buying power can actually reduce what you spend on furnishings. Here's how:
Trade Pricing and Volume Discounts
I have access to trade pricing and volume discounts that most independent homeowners can't access — discounts built over 25 years of purchasing volume and vendor relationships. On a large furnishings package, the savings on materials alone can offset a significant portion of the design fee.
Domestic Sourcing When Tariffs Bite
In 2026, the tariff situation on imported goods — furniture, tile, lighting, and decorative accessories included — is a real variable in project budgets. My deep relationships with American manufacturers mean we can pivot to domestic sourcing without compromising quality when import costs make certain items impractical. This is a genuine advantage that matters right now.
Getting It Right the First Time
The most expensive mistake in interior design is making a decision, living with it briefly, and changing your mind. The wrong countertop, the wrong sofa, the wrong paint color — each "do-over" costs money. Part of what you're paying for with an experienced designer is the benefit of their judgment in reducing those errors before they happen.
The Budget Conversation I Have With Every Client
I'm known in Scottsdale and Paradise Valley for blunt budget honesty. If a client comes to me with a $40,000 budget for a whole-home renovation, I won't tell them we can make it work when we can't. I'll explain what $40,000 can realistically accomplish — maybe a couple of principal rooms done beautifully, phased over time — and what the full project will actually require.
I can estimate within a few hundred dollars on projects that most people would guess cost within tens of thousands. That accuracy comes from 25 years of pricing, purchasing, and living through the gap between what clients expect and what things actually cost.
That honesty doesn't always feel comfortable in the moment. But it prevents the much more painful conversation that happens when someone is halfway through a project with half the money left.
