Work begins on massive $7B development around TSMC in Phoenix Article originally posted on AZ Central on March 27, 2026 Halo Vista, the 2,300-acre development that surrounds the Taiwan Semiconductor Manufacturing Co. plant in north Phoenix, began construction March 26, kicking off a project that will eventually bring 30 million square feet of new development to the area. The development, led by Mack Real Estate Group and McCourt Partners, will cost about $7 billion to develop. The project encircles TSMC’s 1,100-acre site on three sides, located near Interstate 17 and Loop 303. Plans call for several different sub-areas: The town center with residential development, hospitality and dining. That area is planned to have nearly 9,000 apartment units. Lumen Square, planned for retail and hospitality. It will include the auto mall and other commercial development on the northeast corner of the site. The Forge, which will include a technology district and an innovation park for industrial, manufacturing, and research uses. The Sonoran Oasis Research and Technology Park, which will accommodate research and offices, and will partner with Grand Canyon University for research and workforce development. The first phase of the project will include a Costco, two Marriott hotels, an auto mall and industrial space to accommodate suppliers to TSMC, Richard Mack, CEO of Mack Real Estate Group, said. “We need to get buildings up as soon as possible so we don’t miss the momentum,” Mack said of TSMC’s supply chain. His company also developed other supplier sites in the Deer Valley area of north Phoenix for the semiconductor industry. Mack said his team has completed leases and sales totaling about 2 million square feet of space to semiconductor industry suppliers at its existing sites. “We want to get (speculative) development to move fast for leases,” Mack said. “A lot of it is carryover from what we have in Deer Valley.” The group is in escrow to sell two parcels, totaling about 140 acres, in the innovation park, according to Halo Vista marketing materials. It will take between six months and a year before the first industrial buildings will rise from their foundations, Mack said. The rest of the planning and buildout will be responsive to business and community desires, Mack said. He expects high demand for recreation, restaurants and bars, educational facilities and offices. Frank McCourt, the founder and executive chairman of McCourt Partners, said he had been interested in growing his company’s footprint in Phoenix since 2009. McCourt, the former owner of the Los Angeles Dodgers, was the developer of Camelback Ranch, the spring training facilities for the Dodgers and the Chicago White Sox. “This is a dream-come-true type of project,” McCourt said about Halo Vista. “It’s massive in scale and massive in impact.” The possibility of a development like Halo Vista was part of what lured TSMC to come to Phoenix, Chris Mackay, CEO of the Greater Phoenix Economic Council, said. When TSMC first looked at locations in the United States, they did not choose any, because they were looking for a place with a science and technology ecosystem surrounding it, as they have in Taiwan. After hearing that, Mackay said she and other leaders from the city and state approached TSMC again, pitching the possibility of creating a larger, master-planned technology park. “This helps bring to fruition what we promised we could and would do for TSMC at Halo Vista,” she said. Phoenix Councilwoman Ann O’Brien, whose district includes Halo Vista and TSMC, said the flurry of development will give her district the economic depth it needs to provide its residents options for careers and activities, along with new housing and educational opportunities. James Murphy, the CEO of Willmeng, the general contractor for the development, said TSMC and Halo Vista are projects of “global significance.” “Arizona and Phoenix have the ability to create something uniquely our own that drives the future,” he said.
