Every homeowner planning a major renovation wants the same first thing: a number. And every honest builder will tell you the same first thing in response. The number depends on a half-dozen decisions you haven't made yet. That's not evasive. It's the truth of how renovation cost works. The most useful thing we can do in an article like this is walk you through the variables that move the number, and where the largest decisions are made.
Honest Ranges To Start With
These are ranges we see consistently across our own projects in Chandler, Scottsdale, Paradise Valley, Arcadia, and the broader East Valley. They're meant as starting orientation, not quotes.
- Whole-home luxury renovation (4,000–7,000 sq ft, custom-grade finishes, kitchen and primary suite included, mechanical and electrical updated): mid six figures to well past a million.
- Whole-home renovation with significant structural reconfiguration or addition: typically seven figures, sometimes substantially.
- Luxury kitchen renovation (custom cabinetry, integrated appliances, structural changes, real stone, full lighting redesign): mid six figures, often higher with substantial structural work.
- Primary suite renovation (bedroom, bath, closet, often with reconfiguration): low to mid six figures depending on scope and finish.
These aren't ceilings. The most ambitious versions of each of these projects can run two or three times the lower bound, mostly because of choices about specifications, structure, and scope creep that's planned-for rather than reactive.
What Moves The Number
1. Scope Of Structural Change
Moving plumbing across a slab. Removing a load-bearing wall. Raising a ceiling. Adding square footage. These decisions cost real money: engineering, framing, mechanical reroutes, and often foundation work. They're the single biggest reason two renovations with the same finish level can be hundreds of thousands of dollars apart. Knowing this in pre-construction means homeowners can make informed trade-offs while there's still room to.
2. Specification Level
Cabinetry alone can vary by 3–5x between mid-market and true custom. Stone, plumbing fixtures, lighting, hardware, and tile each have a similar spread. None of these decisions are right or wrong in the abstract. They're choices about how the finished home will look, feel, and perform over decades. A clear specification document, written in pre-construction, is how a budget stays anchored.
3. Mechanical And Electrical Scope
Replacing or extending HVAC, electrical service, plumbing supply, and waste lines is often the largest "invisible" cost in a renovation. It rarely shows up in the photos. It's almost always non-negotiable if you want the home to function well for the next twenty years. We treat the mechanical and electrical narrative as a top-line conversation, not a footnote.
4. Site And Existing Conditions
Older homes in Arcadia and parts of central Phoenix routinely surface surprises: outdated framing, asbestos, deficient electrical, settling foundations. Newer homes in master-planned communities are typically cleaner. Pre-construction investigation (selective demolition, structural review, utility verification) is what lets us price what's there rather than what we hope is there.
5. Schedule And Trade Availability
Compressed schedules cost money. They require overtime, premium pricing for materials with shorter lead times, and trade scheduling that's tighter than ideal. Stretched schedules cost money too because supervision and overhead extend with the calendar. The right schedule is the one that lets the work be done well at the pace the trades can hold.
Where Homeowners Get Hurt On Cost
Almost every renovation cost problem we see traces back to one of three things.
Late selections. Materials, fixtures, and finishes chosen during construction rather than before it. Late selections force re-orders, re-installs, and trade re-mobilization, all of which compound into change orders that can run six figures on their own.
Loose initial scope. A scope written too thinly leaves dozens of decisions for the field to make. Every one of those decisions is a place where the build either drifts from the original intent or generates a change order to course-correct.
The wrong team for the project. A team chosen on price tends to deliver to price. On a renovation of any complexity, the difference between an experienced design-build team and a low-bid contractor isn't a percentage. It's the difference between a project that lands and one that doesn't.
What Luxury Cost Buys You
Three things, mostly. The first is craftsmanship that holds up: better materials installed by better trades and supervised at a higher standard. The second is the experience of the project: knowing where you stand, when you can move home, what's left to decide, what's already done. The third is the absence of surprise: a build that lands on the timeline and budget the team committed to in pre-construction, because the work to make those commitments honest happened before construction started.
That's the actual product. Marble is just one piece of it.
How To Think About Your Number
If you're planning a renovation, the most useful early step isn't getting a quote. It's a candid conversation with a firm that can pressure-test your vision against your investment in the first meeting. That conversation will tell you whether the project you're imagining is in range, what would have to shift if it isn't, and what kind of team it'll take to deliver it well. We're always happy to be one of those conversations, with no strings attached.
