Real estate developer Panattoni has taken over a Meta-backed proposal to build a 430-acre data center in southern Wisconsin.

The project, located across the towns of Beloit and Turtle, was previously set to be developed under Cambrin LLC, which has the same name and email address listed in documents connected to Meta’s confirmed data center in Beaver Dam, Wisconsin.

But the Town of Beloit’s Administrator, John Malizio, told the Beloit Daily News last Friday that Panattoni had reached out to say that they were taking over the project.

Panattoni seems to have set up two websites about the data center. Neither could be accessed at time of writing.

Project Cornmaze has attracted a substantial amount of opposition from residents in Beloit and Turtle.

A public Facebook group called “No Beloit Data Center” has amassed around 2,700 members at time of writing. A widely circulated flyer proposes that residents call on the State Governor to issue a moratorium on data center construction and request county and local authorities to ban NDAs between developers and governments.

The property is currently owned by Rock Road Companies Inc, based in Janesville, Wisconsin. The pre-development agreement has been under negotiation since June 2025.

Beloit sits on the border between Wisconsin and Illinois in Rock County.

Founded in 1986 as an industrial real estate firm, Panattoni Development has developed around 625 million square feet of office, logistics, and industrial space in the US alone.

In August 2024, the company said that it would begin developing data centers, setting itself a target to develop 1GW of data center capacity by 2030.

According to the company’s website, it has 21 “active” data center projects.

The company also has a European unit, which got its own data center team in July 2025 after poaching several former staffers from Colt Data Centre Services.
