Deloitte Signs DC’s Largest Lease of 2025

Morgan Stanley Real Estate landed last year’s biggest lease in the Greater Washington area, getting the deal done under the wire.

Deloitte renewed 600,000 square feet at Morgan Stanley’s 1919 North Lynn Street in Rosslyn, Virginia, the Washington Business Journal reported. The renewal accounts for virtually all of the building’s leasable space and was initially disclosed in a quarterly CBRE report.

The firm has had at least a small footprint at the building for the past 15 years, but has slowly vacuumed up the entirety of the property, notably checking in at 450,000 square feet in 2018. That was a year after a Morgan Stanley Real Estate affiliate purchased the 624,000-square-foot building for $460 million, or a local record of $711 per square foot.

Details about the lease renewal were not disclosed, though Deloitte previously subleased space at the building from CEB, which pre-leased the entire building in 2004, four years ahead of its completion.

It’s also unclear if the lease kicks in immediately or when its old lease expires in 2028; Deloitte confirmed the lease but did not divulge any more information to the Business Journal.

Regardless of the details, the size of the lease is a victory for Washington, D.C.’s office market. The 600,000-square-foot lease easily edged out other top contenders for the region’s largest of 2025, such as the Department of Justice’s 477,000-square-foot renewal at the Liberty Square Building.

In fact, Deloitte is responsible for one of last year’s biggest office leases in another major market, too.
