A building permit was filed this week for a wall sign with a new name in downtown Rochester.
The permit calls for a wall sign for "X One" at 202 Fourth St. SW. The permit doesn't says if the sign will be in the One Discovery Square complex, though that is the only building on that block.
Developer Twin Cities-based M.A. Mortenson Co. didn't respond to questions about who or what "X One" is.
The center's website seems to suggest that "X One" might be a new name for One Discovery Square. A new logo that resembles an X is now in use throughout the site. The letter X is used as a motif in a new brochure for the building with headers like, "Access X Mayo Clinic," "Culture X Place" and "Site X Location."
Mortenson recently filed plans for Two Discovery Square" next to the first building, so X One could be a way to identify the properties, which will be next to each other.
X One could possibly be a new tenant for the five-story complex, which saw Café Steam start brewing coffee there this week.
Announced tenants for the complex include Mayo Clinic, the University of Minnesota Rochester, Epic Systems, Boston Scientific and Amsterdam-based Royal Philips.
While it hasn’t been officially announced, building permits also show a joint partnership between Mayo Clinic and a Chinese firm called WuXi Diagnostics is taking space on the third floor.
Whatever it is called, the complex is the latest development in DMC's 16-block Discovery Square sub-district described to be a "hub for bio-medicine, research and technology innovation."
The site development also maps out "an approximate future location" for a much smaller Three Discovery Square building on a grassy area at the southwest corner of Third Avenue Southwest and Fifth Street Southwest.
