Major addition on the way at Dallas’ landmark Infomart

A new data center and office building is planned northwest of downtown.

The owners of Dallas’ landmark Infomart building are planning another expansion.

California-based data center giant Equinix in 2020 completed a $140 million addition to the huge building on Stemmons Freeway northwest of downtown.

Equinix in 2018 paid a record $800 million for the white-filigreed Infomart, which was built in the 1980s as a tech industry wholesale trade center.


Now Equinix is planning an even bigger addition — a $180 million project set to start later this year. The more than 211,000-square-foot project at 1990 N. Stemmons Freeway will include a four-story office and a four-story data center, according to planning documents filed with the state.

With the latest expansion, Equinix will have invested more than $1.1 billion in the Infomart property. The original 1.6 million-square-foot data center and office building was patterned after London’s famed 19th century Crystal Palace.

In 2005, the Infomart was sold out of foreclosure for just more than $100 million. Since acquiring the building almost five years ago, Equinix has converted more and more of the property to data center use.


Equinix is one of the world’s largest operators of data centers, with facilities in the Americas, Asia, the U.K., Europe, Africa and the Middle East.

Dallas-Fort Worth is one of the country’s top data center markets, with more than 2 million in new projects in the works.
