A Chantilly office has landed AT&T for a rare full-building lease.

In late February, the telecommunications company signed a lease for 111,000 square foot at 4807 Stonecroft Blvd, part of the Westfields International Center at Dulles office park. It will take over the building in 2025 under a long-term lease, building manager Stream Realty Partners announced on Feb. 29.

“We are excited to welcome AT&T to Stonecroft IV and into our regional portfolio,” said Max Sanford, a partner at Menlo Equities, which owns the building. “Their decision to lease the entire building reaffirms the strength of the property’s offerings and its strategic location, and we look forward to their long-term occupancy in the building.”

The building includes new amenities like a fitness center, lounge, upgraded lobby and conference center.

The move comes as AT&T consolidates its Virginia offices, according to Bisnow. Plans for mixed-use development on the company’s longtime corporate campus at 3033 Chain Bridge Road in Oakton are already in the works.

Here’s more from Bisnow on how Stream Realty Partners landed the lease:

The telecommunications giant is consolidating from multiple Virginia offices, including 3033 Chain Bridge Road in Oakton, Stream Realty co-Managing Director Jeff Roman told Bisnow. Its Oakton building is slated for a 1.5M SF redevelopment from EYA and Carlyle Group.

The 4807 Stonecroft building had been occupied by Northrop Grumman starting in 2008, but the defense contractor vacated a few years ago, said Roman, who leases the building along with Stream Executive Vice President Malcolm Schweiker.

After Northrop Grumman left, then-owner Franklin Street Properties Corp. worked with the Stream brokers to secure an agreement with another defense contractor, Roman said, declining to name that firm. Franklin Street renovated the building as part of the effort to bring in that tenant, but the company decided not to proceed with the deal due to pandemic-related shifts, Roman said.

Franklin Street sold Stonecroft IV and another Chantilly building to Menlo Equities in November 2021 for $40 million. The Stonecroft building was vacant at the time, according to the Washington Business Journal.

Stream Realty Partners also touted the building’s location for providing “unparalleled connectivity” to government operations, including the CIA and FBI.

“This whole building lease represents another great office success in Westfields and continues to show commercial resilience in the Westfields community,” Westfields Center said in a statement welcoming AT&T.
