Data center operator CoreSite has new admin privileges downtown.
The Denver-based business purchased the 171,000-square-foot 910 15th St. building Wednesday for $38 million, public records show.
“With this expansion, we’ll be able to better support the growing demand for data centers in the Denver area, as companies continue their digital transformations and as AI becomes even more engrained in our work and everyday lives,” CoreSite said in a statement provided to BusinessDen.
The deal works out to $222 a square foot for the Denver Gas & Electric Building, a city landmark constructed in 1910. Today, it serves as a telecommunications hub, housing several data centers inside, including CoreSite’s 32,000-square-foot space.
“While the building may be more than 100 years old, it’s packed with 21st Century technology for computing and telecommunications,” CoreSite said.
The seller, DGEB Management LLC, purchased the property in late December 1997 for $5 million.
CoreSite described the building as “the largest and busiest carrier-neutral facility in the region,” meaning the tech inside can be powered by a wide variety of service providers. Other tenants in the building include Lumen, formerly known as CenturyLink.
The data center company also operates one at 639 E. 18th Ave. in Uptown. It’s currently building a 97,000-square-foot facility at 4900 Race St. near the National Western Center in Elyria Swansea.
That building will be the first in CoreSite’s planned 322,000-square-foot data center campus on its 15 acres there.
