CyrusOne plans another data center expansion at its 90-acre Allen campus

One of North Texas’ biggest data center campuses is growing again.

CyrusOne broke ground in 2017 on the first phase of its 90-acre tech complex on Chelsea Drive in Allen. It’s one of the largest data center campuses in Texas, planned for almost 1 million square feet of construction, according to CyrusOne.

In August, the company filed plans for a $50 million, 82,750-square-foot expansion of the complex near U.S. Highway 75.

Now CyrusOne is signaling that it will start work after the first of the year on another $31 million, 126,005 square foot addition, according to planning documents filed with the state.

The project is described as a “new construction, single-story data center with two-story office component.”

Construction is scheduled for completion late next year. JHET Architects is designing the project.

Based in Dallas, CyrusOne has more than 50 high-performance facilities worldwide serving almost 800 customers.

Along with the Allen campus, CyrusOne has Texas data centers in Austin and San Antonio. In 2021, the company was acquired by investors KKR and Global Infrastructure Partners in a $15 billion deal.

Dallas-Fort Worth is one of the country’s fastest growing data center markets, with millions of square feet of new projects on the way.

Google recently announced plans for a more than $600 million data center in Red Oak south of Dallas. The first phase of the project will be about 285,000 square feet.
