ALEXANDRIA, VA-Two class A office buildings in the Carlyle submarket have been put on the block, with Eastdil Secured retained as the exclusive broker. The two buildings, which total 368,224 square feet, are located at 1940 and 2000 Duke St.

Originally build-to-suit headquarters, both buildings are located very close to the 2.5-million-square-foot Patent and Trademark Office. In fact, one of the properties--1940—was developed in 2003 for Oblon Spivak, a patent and trademark law firm. The building will continue to serve as its worldwide headquarters. The six-story, 212,889-square-foot building is 100% leased. The 2000 Duke St. asset was developed in 1997 for Time-Life Inc. before its reorganization. Now anchored by the Motley Fool, the five-story, 155,335-square foot asset is 98% leased.

Besides their proximity to PTO, another of the properties’ main selling points is their location in Carlyle, Alexandria’s central business district. John Kevill, managing director of Eastdil, says in a statement that Carlyle is the highest-performing office market in Alexandria with a vacancy rate of less than 9%.

“Over the past 15 years, class A rents there have grown by nearly 4%, and they’re expected to accelerate as the Patent and Trademark Office expands beyond its campus into surrounding buildings,” he says. Eastdil was unable to return a call to GlobeSt.com in time for publication.

Eastdil also recently secured the listing for San Francisco-based Shorenstein’s Hamilton Square, a trophy property located at 600 14th St., NW. In an earlier interview Kevill told GlobeSt.com he expects that 248,495-square-foot building to trade for about $200 million.
