There is over $300 billion committed to Phoenix right now — some already in the ground, the rest filed, funded and on the way. For a century Phoenix was a place you passed through on the way to somewhere else; that era is ending, and the valley is becoming the place things actually get built.
Below are the six biggest projects reshaping the city, drawn from filings rather than press releases. A few of them look different than the headlines suggested, and together they are redrawing the map of where it makes sense to live.
How big is the TSMC campus in North Phoenix?
TSMC's total commitment in North Phoenix now stands at $265 billion on a 900-acre campus — for perspective, Arizona's entire economy produces about $620 billion a year. The company raised its bet again this summer.
The plan is now ten chip plants, two advanced packaging facilities and a research center. Roughly 3,500 people already work there. The first plant is producing, and the second is built and begins producing three-nanometer chips next year — the kind that go into the newest phones and AI systems. When the full buildout is done, roughly 30% of the world's most advanced chip capacity will sit in North Phoenix rather than in Asia.
Chip plants don't come alone. Suppliers, packaging companies and the businesses that feed them follow, and every one of those workers needs somewhere to live. That is the engine behind what's happening in the North Valley.
Is Belmont still being built as a new city west of Phoenix?
No. The 24,000-acre plan to build a city from scratch west of Phoenix isn't happening as a city.
The plans quietly shifted away from residential toward heavy industrial and energy. In 2023, 1,100 acres were carved out for a movie studio and another 5,000 went heavy industrial. In January, another thousand acres went to the county for the same purpose. Right next door, 2,000 acres that had been approved for 5,700 homes flipped to a data center campus instead, with a gigawatt of power behind it.
That empty desert is turning into a power corridor, because that is what the chip economy actually needs. The rooftops didn't vanish — they moved closer in, to places that already have water and roads. That pattern repeats across every project here.
Why aren't more empty downtown offices becoming apartments?
Because most buildings can't physically accommodate the conversion. The developer who just bought one downtown tower to convert says he looks at a hundred buildings to find one that works.
So what made this one work? A 19-story tower at the Arizona Center built in 1990, with 13-foot floor heights and floor-to-ceiling glass on every side. You need a window in every room and ceilings you can run ductwork through, and you can't add either one later. It became a 340-room JW Marriott, a $200 million project.
Meanwhile, the retail centers below filled to 100% with local spots — a steakhouse, a seafood place. That's what's actually bringing downtown back. Not the towers, the street.
What is the new entertainment district near Scottsdale?
It's a $100 million entertainment district called Sydney, on Salt River Pima community land. The attention-grabbing piece is a bar built entirely of ice — chairs, tables and the bar itself inside a walk-in freezer — but that's the gimmick, not the story.
The real lineup includes a Hard Rock Hotel, a Japanese food hall, City Winery, The Rustic and two new concepts from the group behind Bourbon & Bones. Leases were signed this year, with doors opening in 2027 and 2028.
Why isn't it in the middle of Scottsdale? Central Scottsdale is out of land, so the growth is jumping to the edges. The money goes where the dirt is.
Where will the chip workers live? Look at North Peoria.
North Peoria is where a lot of this demand is landing, specifically a 5,300-acre, billion-dollar community called Saddleback. Five builders committed all at once in a year everyone else called slow.
Bernard and Taylor Morrison are already building the first 572 homes. David Weekley, Camelot and Toll Brothers are next, with models breaking ground in November. Pricing starts in the low $700s for homes between 2,000 and 2,500 square feet, and runs from the mid-$800s for bigger lots up to 3,500 square feet with an RV garage. The whole thing sits about 15 minutes from the TSMC campus.
I'll be straight with you: buying in phase one of a community like that means dust, construction and a drive for groceries for a while. That's the trade, and it's exactly the kind of decision you want someone in your corner for. If this corridor is the reason you're reading, lets book a call and we'll pick it up from there.
How does the new Texas-to-Phoenix pipeline change things?
Arizona has zero oil refineries. Every gallon of gas arrives on two pipelines — one from California, one from Texas — and both take about a week to get here. If you were here in 2003 when one of them broke, you remember the gas lines.
A $5 billion, 1,300-mile pipeline from Texas straight to Phoenix was just approved, carrying 230,000 barrels a day. The California line gets reversed, so fuel that used to flow into Phoenix will flow out of Phoenix to California and Nevada. Phoenix stops being the end of the line and becomes the hub.
Chips get made here. Cars get built here. Now fuel routes through here. The state keeps turning into the nexus of things instead of the edge of things.
What does all of this mean if you're buying or already own here?
The map of where to live in the Valley is being redrawn in real time, so location decisions carry more weight than they used to. If you're moving here for one of these jobs, where you land matters. If you already live here, what's getting built around you matters.
Either way, the worst move is deciding off a headline.

The takeaway
Phoenix is no longer a pass-through city, and the growth is concentrating where there's already water, road and power — not in the places the headlines promised. Craig Bennett tracks these filings so you can make a smart move instead of an emotional one; when you're ready to talk specifics, book a call.
Frequently Asked Questions
How much is TSMC investing in North Phoenix? TSMC's total commitment is now $265 billion on a 900-acre campus in North Phoenix. The plan includes ten chip plants, two advanced packaging facilities and a research center, with roughly 3,500 people already employed there.
Is Belmont, the city west of Phoenix, still happening? Not as a city. The 24,000-acre project shifted toward heavy industrial and energy uses, including 1,100 acres for a movie studio, thousands of acres of heavy industrial land, and a neighboring 2,000-acre site that flipped from 5,700 approved homes to a gigawatt data center campus.
How far is Saddleback in North Peoria from the TSMC campus? About 15 minutes. Saddleback is a 5,300-acre, billion-dollar community with five builders committed, and pricing starts in the low $700s.
What are home prices in Saddleback? Pricing starts in the low $700s for homes between 2,000 and 2,500 square feet, and runs from the mid-$800s for larger lots up to 3,500 square feet with an RV garage.
Why do so few Phoenix office buildings convert to apartments? The physical requirements are hard to meet. A conversion needs a window in every room and ceilings tall enough to run ductwork through, and neither can be added later — one developer reported reviewing about a hundred buildings to find a single viable candidate.
What is being built in the Sydney entertainment district? Sydney is a $100 million district on Salt River Pima community land featuring a Hard Rock Hotel, a Japanese food hall, City Winery, The Rustic, two concepts from the Bourbon & Bones group and a bar built inside a walk-in freezer. Leases were signed this year with openings in 2027 and 2028.
