The Biggest House in Arizona: 8 Massive Mansions That Define Desert Luxury
The first time I drove up Sugarloaf Mountain in Paradise Valley, I slowed the car without meaning to. A stone wall kept running along the road, longer than any property line I’d measured before, and I remember thinking: whoever built this wasn’t just building a house. That’s the moment I got curious about the biggest house in Arizona.
I’m Stefano Schiavon, founder of rivon home, and I’m going to walk you through eight of the Biggest House in Arizona here — the true giant is the McCune Mansion — and there’s a lot more behind that 52,000-square-foot number than it first appears.
Where the The Biggest House in Arizona Is Located
Most of The Biggest House in Arizona sit in Paradise Valley, a small, wealthy town wedged between Phoenix and Scottsdale at the base of Camelback Mountain. Strict residential zoning keeps out malls and office parks here, which is exactly why the lots got room to grow.
A second cluster sits in North Scottsdale, around gated golf communities like Silverleaf at DC Ranch. One property, still shrouded in mystery, sits far out in Cave Creek on 200 acres of raw desert. Location decided almost everything about how big these homes could get — hillside acreage and desert lots gave architects space that coastal cities never had.
Touring Biggest House in Arizona
I’ve driven the Paradise Valley loop enough times to know which walls hide which mansions, even if I can only see rooflines from the street. The Biggest House in Arizona The McCune Mansion sits high enough on its hill that you can catch pieces of its stonework from below, especially once the sun drops behind Camelback Mountain.
Most of The Biggest House in Arizona are private, so what I know comes from public listing photos, county records, and time spent looking up at gates I can’t walk through. Even from the curb, though, the scale of these estates changes how a whole street feels.
McCune Mansion: Inside The Biggest House in Arizona
The Biggest House in Arizona The McCune Mansion was built starting in the early 1960s on Sugarloaf Mountain for Walker McCune, an oil-fortune heir tied to Pennzoil, who spent roughly $5.4 million (close to $49 million today) chasing a vision he never got to finish. He died before construction wrapped, and a bitter divorce meant he never actually lived there. Here’s what’s built into the estate:
- Size: 52,000 square feet
- Bedrooms: 12 in the main house, plus a detached 2,900-square-foot guest house (14 total)
- Bathrooms: 23 across the property
- Lot: 3.77 acres, with two adjoining parcels bringing the full site to nearly 6 acres
- Pool: Olympic-sized, with his-and-hers locker rooms
- Ice rink: built for McCune’s wife, an avid skater
- Entertaining space: a 150-seat theater and a full ballroom
- Views: 360 degrees, taking in Camelback Mountain, the Praying Monk rock formation, Phoenix Mountain Preserve, and South Mountain
Every material choice leaned dramatic — exterior stonework, patterned concrete, marble floors, and a fireplace clad in amethyst. It’s the kind of build you only see when a client stops asking what things cost.
Fitness-chain owner Gordon Hall, and later Geordie and Jamie Hormel of the Hormel Foods family, owned the estate after McCune. The Hormels bought it in 1991 for $3.75 million, listed it for $16 million in 2022, and finally sold it in May 2026 for $9 million to a Florida investor who plans to put roughly $40 million into renovating it.
7 More of The Biggest House in Arizona
Here’s a look at the rest of the Biggest House in Arizona — where they sit, how big they are (or claim to be), and what makes each one worth knowing.
Blue Sky Preserve — Cave Creek
- Location: 200 private acres north of Cave Creek
- Size: roughly 60,000 square feet, if the original plans were followed
- Status: under construction, unfinished for over a decade
- Special detail: four artificial lakes and an owner shielded behind a Delaware corporation
Neighbors spent years guessing what was rising out of the desert — a cult compound, a car dealership, even a resort. It turned out to be a private home, originally tied to tech entrepreneur Jason Hope, who threw a lavish party at the unfinished site in 2010 with a performance from Ludacris, shortly before a lawsuit stalled construction.
The Biggest House in Arizona sold in 2014 to Idaho developer Michael Matzek, and there’s still no public record of it ever being completed. If it’s truly built out at 60,000 square feet, it would outsize even the McCune Mansion — but until that’s confirmed, the title stays with McCune.
Mockingbird Lane Estate — Paradise Valley
- Location: Paradise Valley
- Size: 20,919 square feet
- Bedrooms/Bathrooms: 8 bed / 11 bath
- Sold: July 2026, for $40.24 million — an Arizona record
- Special detail: an indoor go-kart track, a private shooting range, and an 18-car garage
This one isn’t the biggest by square footage, but it now holds Arizona’s all-time sale-price record, beating a $33.5 million deal from February 2025. Along with the go-kart track and shooting range, it has a spa with pedicure stations, two 432-bottle wine walls, and a ramada built for entertaining. It’s proof that in Arizona, the biggest price tag and the biggest floor plan don’t always belong to the same house.
Charles Barkley’s Estate — Paradise Valley
- Location: Paradise Valley
- Size: approximately 27,000 square feet
- Lot: 2.43 acres
- Bedrooms/Bathrooms: 10 bed / 13 bath
- Special detail: a full indoor basketball court
The former Phoenix Suns star and NBA Hall of Famer has held this Paradise Valley property for decades, long after his playing career ended. At roughly half the size of the McCune Mansion, it’s still the biggest home actually owned by a celebrity in Arizona, with a wine cellar, home theater, and a resort-style pool built around it.
Campbell Cliffs — Tucson
- Location: Catalina Foothills, Tucson
- Size: approximately 25,000 square feet
- Status: listed for $12.95 million
- Special detail: Tucson’s largest and priciest home currently on the market
Tucson doesn’t compete with Paradise Valley on scale, but Campbell Cliffs is the closest thing the city has to a true mega-mansion, set into the Catalina Foothills with sweeping desert views.
Alex Meruelo’s Former Compound — Paradise Valley
- Location: Paradise Valley
- Lot: 9 acres
- Sold: for $30 million
- Special detail: multiple guesthouses and a private lookout tower
Built for the billionaire former owner of the NHL’s Arizona Coyotes, this compound traded acreage for square footage — the 9-acre lot is larger than most estates on this list, even though the main house itself is smaller than McCune or Barkley’s.
Silverleaf Mansion — North Scottsdale
- Location: Silverleaf at DC Ranch, North Scottsdale
- Community features: a Tom Weiskopf-designed golf course, clubhouse, and spa
- Special detail: guard-gated, resort-style living that draws entertainers and athletes who want privacy without leaving the Valley
Individual home sizes inside Silverleaf aren’t always public, since many buyers close through LLCs, but the community itself is where North Scottsdale’s biggest private estates cluster.
The Big House — Gilbert
- Location: Gilbert, Arizona
- Type: vacation rental, not a private mansion
- Size: 8 bedrooms, 5 bathrooms, roughly 1 acre
- Special detail: a private pickleball court, pool, and hot tub
Worth mentioning only because so many people search for “the big house” in Gilbert expecting a mansion. It’s actually a well-known short-term rental, popular for group getaways — a different kind of big than the estates above.
Which of The Biggest House in Arizona Sold, and Which Are Still Unfinished
The Biggest House in Arizona The McCune Mansion sold in May 2026 for $9 million. The Mockingbird Lane Estate sold in July 2026 for $40.24 million, setting the state’s price record. Alex Meruelo’s former compound sold for $30 million.
Campbell Cliffs is currently listed but unsold, and Barkley’s estate and the Silverleaf homes remain private residences, not on the market. Blue Sky Preserve, despite more than a decade of construction, has never been publicly confirmed as complete — and county records, searchable through the [Maricopa County Assessor’s Office], still show construction-era details on file for the parcel.
Mysteries, Records, and Stalled Construction
A few of The Biggest House in Arizona carry stranger stories than their square footage suggests. Blue Sky Preserve stalled in 2011 after its original owner faced a lawsuit over a text-messaging business, and construction hasn’t visibly resumed in the years since, even after a second owner bought it in 2014 with plans to finish the job.
The McCune Mansion changed hands quietly for decades before its 2026 sale finally made headlines, while the Mockingbird Lane sale broke a price record that had only been set the year before, in February 2025. Arizona’s luxury market keeps resetting its own bar every year or two.

Other Notable Biggest House in Arizona Worth Knowing
A few more names round out the state’s list of oversized homes, even outside the top eight above.
- Bennett Dorrance’s Camelback compound — the Campbell Soup heir’s roughly 11,000-square-foot estate sits at the base of Camelback Mountain.
- The Wrigley Mansion — a historic Phoenix landmark the Hormel family also owned for a time, buying it in 1992 for $2.6 million, a year after purchasing the McCune Mansion itself.
If you’re designing at any scale — not just a 50,000-square-foot one — our Home Decor category has practical ideas for making a home feel intentional, whatever size you’re working with.
It’s worth noting, as someone who studies healthy building design for a living, that scale like this comes with real costs. Homes this size demand serious thought around energy use and water in a desert climate, something groups like the American Institute of Architects have pushed the profession to take seriously, even at the luxury end of the market.

Final Thoughts
Chasing down the biggest house in Arizona taught me that square footage is only half the story. The McCune Mansion holds the title by size, the Mockingbird Lane Estate holds it by price, and Blue Sky Preserve might quietly hold it by ambition, if it’s ever finished.
Whether you’re curious about the biggest house in Arizona out of pure curiosity or planning something big of your own, the lesson is the same one I keep coming back to: a home this size only means something when the story behind it is just as big.
