CoreSite Realty Corp. to develop Reston data center site

Published August 16, 2016 by Robert Powell, III

Denver-based data center company CoreSite Realty Corp. plans to greatly expand its presence in Reston, building more than more than 660,000 square feet of new data center capacity.

The company said it may invest $400 million to $500 million in a multi-phase build-out of the Sunrise Technology Park (STP), a 21.75-acre, light-industrial/flex office park in Reston.

The company is paying more than $60 million for STP, which is located less than a mile from CoreSite's existing Reston buildings.

The STP site now has four buildings totaling 315,000 square feet. CoreSite estimates that it could build more than 660,000 square feet of new data center capacity.

Coresite expects to invest $90 million in the first phase of its plan. That phase will include redeveloping an existing 48,000-square-foot industrial building to data center use, building a 92,000-square-foot data center shell, and constructing another 92,000-square-foot structure to house centralized infrastructure supporting the full buildout of the campus. 

CoreSite expects to begin construction during the third quarter of 2017, and substantially complete work in the second quarter of 2018.

CoreSite expects to continuing investing in the campus in additional phases to meet customer demand.

The company’s current Reston campus includes two facilities totaling over 390,000 square feet of data center capacity.

Construction of all 660,000 square feet of new capacity envisioned by CoreSite at the STP expansion would increase CoreSite's capacity at its Reston campus to more than 1 million square feet.
