The company, via its Stone Applications LLC subsidiary, has filed for Redhawk Phase 2; a 280,000 sq ft (26,010 sqm) building at Google’s existing campus on East Elliot Road and South Sossaman Road, in the Mesa area of the city.

It also applied for permission to build an office development known as Redhaw Hub. Timelines for either development weren’t shared.

Google broke ground on the first building at the Mesa campus in July 2023.

The site, which has been in the works since 2019, will span 750,000 square feet (70,000 sqm) once fully built-out on 187 acres of farmland.

The first 288,530 sq ft (26,805 sqm) phase is reportedly due live in July 2025, and set for full build-out across three phases by 2030.

Phoenix is a major data center hub, with the Mesa area home to Polish software firm Comarch as well as EdgeCore, Meta, Novva, Apple, CyrusOne, and NTT. Amazon is planning two campuses in Mesa, while landowner Pacific Proving is also planning to develop a large campus in the area.

Across the rest of Phoenix, the likes of Stack, Stream, Prime, Aligned, Iron Mountain, Vantage, Compass, QTS, EdgeConneX, Expedient, and H5 are all present. Microsoft operates a cloud region out of the area.
