PHOENIX — Willmeng Construction has officially broken ground on Halo Vista, a massive $7 billion mixed-use development designed to complement the nearby Taiwan Semiconductor Manufacturing Company (TSMC) campus in northern Phoenix.

Spanning approximately 2,300 acres, the project is being positioned as a “city within a city,” capitalizing on the rapid growth of semiconductor manufacturing and the influx of talent and investment into the region.
The development sits immediately adjacent to TSMC’s $65 billion fabrication campus, one of the largest advanced manufacturing investments in the United States, and is expected to serve as a hub for innovation, commerce and residential growth.
Halo Vista’s master plan includes nearly 30 million square feet of mixed-use space, encompassing industrial, manufacturing, office, retail, residential and educational components.
Mack Real Estate Group and McCourt Partners are co-developing the project, which was first unveiled in 2024 after securing development rights from the Arizona State Land Department.
Initial tenants already lined up for the development include Costco, a multi-parcel auto mall designed for dealership use, and a dual-branded hotel featuring Marriott brands — Courtyard and Residence Inn.
“We’re excited to get this project started and to begin to see the potential that Halo Vista holds for the Valley and even on a larger scale,” said James Murphy, Willmeng’s CEO, in the news release.
Willmeng will lead early-phase construction, focusing on horizontal infrastructure such as site preparation, utilities and foundational groundwork needed to support future vertical development.
The Halo Vista project is closely tied to the ongoing semiconductor and onshoring boom reshaping the Phoenix metro area.
The TSMC campus has become a cornerstone of that growth, attracting a wave of construction activity and positioning the region as a national hub for advanced manufacturing and technology development.
According to a recent outlook from LGE Design-Build, the Phoenix construction market is beginning to stabilize after several years of rapid expansion.
“The Phoenix market entered late 2025 showing clear signs of stabilization after several
years of outsized growth and elevated delivery volumes,” the report read. “Across all major product types, demand remains intact, but the environment favors cost control with increased emphasis on projects that align closely with tenant demand and market timing.”
Major contractors are continuing to expand their presence in the region. PCL Construction opened a new commercial office in Phoenix, citing strong growth in aviation, hospitality and retail sectors, while Suffolk has made leadership hires to strengthen its position in advanced technology markets.
Halo Vista reflects a broader shift in U.S. construction driven by reshoring efforts and federal incentives aimed at boosting domestic semiconductor production. Developments like this are not only industrial projects but also ecosystem builders — combining housing, services and commercial infrastructure to support long-term workforce needs.
The site’s strategic location along Interstate 17 and Loop 303 enhances its accessibility, making it attractive for both logistics and commuter traffic. As the region continues to grow, transportation infrastructure will play a critical role in supporting increased population and economic activity.
In addition, large-scale master-planned developments tied to single anchor employers — such as TSMC — are becoming more common, mirroring patterns seen in earlier tech-driven expansions in other U.S. markets.
With billions in investment already flowing into the Phoenix area, Halo Vista could emerge as a central node in the region’s transformation into a leading semiconductor and innovation corridor.
