Procter & Gamble Expands Mason R&D Campus

Published 10/28/2025

Procter & Gamble is engaged in a $450 million expansion of the Mason Business Center in Ohio. Designed by HDR, the transformative project comprises two new three-story buildings that will provide best-in-class laboratory and office space to catalyze R&D innovation. Researchers with diverse domains of expertise will be strategically colocated to drive collaboration and streamline the implementation of new technologies. 

One 360,000-sf facility will support product research and operations for the Baby and Family Care division and will connect to the east wing of the existing development. On the west side, a 130,000-sf structure will house functions for the Baby and Feminine Care department, as well as accommodating a consumer research hub spanning between 7,000 and 10,000 sf. 

Created in partnership with the Mason Port Authority through a lease-leaseback model, the expansion is being delivered by Messer Construction and Triversity Construction. Kleingers Group is serving as civil engineer with IMEG as electrical engineer. Completion is anticipated in 2030.
