TSMC and Halo Vista: Reshaping the Future of North Phoenix

If you've driven north on I-17 recently, it's impossible to miss the massive TSMC campus rapidly rising from the desert. Tower cranes, construction crews, and sprawling new facilities have become a familiar sight as one of the largest economic development projects in Arizona history continues to take shape.

According to TSMC Arizona, more than 3,500 employees already support the manufacturing of some of the most advanced semiconductor technology produced in the United States. Yet what we see today is only the beginning.

According to a recent Reuters report, Taiwan Semiconductor Manufacturing Co. plans to open an advanced chip packaging facility in Arizona by 2029. Reuters also reported that construction activity associated with the planned facility has already begun. TSMC currently has three fabrication plants planned or under development in north Phoenix, with additional manufacturing, packaging, and research facilities announced as part of its broader $165 billion U.S. expansion. Together, these investments are expected to bring thousands of additional jobs and further establish North Phoenix as a leading technology hub.

The growth extends well beyond the TSMC campus itself.

Just south of Carefree Highway, the ambitious Halo Vista development is rapidly moving from vision to reality. What was once 2,300 acres of vacant desert land is now being transformed into a master-planned community designed to support the region's expanding workforce and economic growth.

Developed through a partnership between Mack Real Estate Group and McCourt Partners, Halo Vista's first phase includes approximately $7 billion in infrastructure and site preparation. According to project announcements, Willmeng Construction is leading the initial horizontal development work. Mack Real Estate Group acquired the property through an Arizona State Land Department auction in May 2024 for approximately $56 million.

When completed, Halo Vista is expected to feature approximately 30 million square feet of commercial space, including industrial, retail, office, research, healthcare, hospitality, and innovation-focused development, along with nearly 9,000 residential units.

Several major projects have already been announced. Anchor tenants include Costco and a large auto mall being developed by De Rito Partners that could ultimately feature as many as a dozen dealerships. The planned auto mall is expected to be located near the Ben Avery Shooting Facility and is anticipated to become a significant regional destination. Plans also call for a five-story Marriott hotel, further expanding the area's commercial and hospitality offerings.

According to the Halo Vista project website, "Halo Vista is positioned to become a hub for science and innovation, driving economic growth and attracting world-class talent to the region."

For North Phoenix residents, this transformation represents more than new buildings and construction activity. The area has long been known for its strong neighborhoods, outdoor recreation opportunities, and high quality of life. What's arriving now is the economic depth to match it.

The combination of TSMC's historic investment and Halo Vista's mixed-use development has the potential to reshape the North Valley for decades to come, creating new employment opportunities, attracting additional businesses, and increasing demand for housing, services, and infrastructure throughout the region.

For homeowners, the impact could be significant. Major employment centers often create demand for housing, retail services, restaurants, healthcare facilities, and supporting businesses. While real estate markets are influenced by many factors and no outcome is guaranteed, projects of this scale have historically contributed to long-term economic growth and housing demand in surrounding communities.

Whether you're a homeowner, buyer, investor, or simply someone who calls North Phoenix home, these projects are worth watching. The future of the North Valley is no longer a distant vision—it's being built right now.
