Work has begun on Halo Vista, a $7 billion mixed-use development rising next to TSMC’s north Phoenix campus. Backers say the project is meant to fulfill Arizona’s original promise to the chipmaker by creating a nearby ecosystem where suppliers, engineers, and manufacturers can work in close proximity. Once built out, Halo Vista is expected to deliver roughly 30 million square feet of space across office, industrial, retail, and research uses, plus about 9,000 housing units, making it one of the region’s most ambitious long-term growth projects.
The first phase is centered on the site’s eastern edge near Interstate 17 and is being positioned as the early commercial anchor for the broader vision. A new Costco, expected to open in the first half of next year, is set to be the first major user, alongside an auto mall, restaurant and retail space, and two Marriott hotels being developed by Common Bond Development Group. Infrastructure and site preparation are already underway, with Willmeng Construction leading that early work, while developers say they are also beginning to focus on the larger research, engineering, and manufacturing districts planned for later phases.
Halo Vista is part of a much wider wave of development around TSMC that is reshaping north Phoenix. Other major proposals include the 7,000-acre NorthPark master plan and Vestar’s Dove Valley Towne Center, both aimed at capturing the demand expected from the area’s industrial and population growth. Public infrastructure is moving in parallel, with the Arizona Department of Transportation advancing a $129 million Loop 303 and I-17 interchange project to support rising traffic and improve access to the fast-growing corridor.
