District records list 1001 Pennsylvania Ave.'s proposed 2005 assessed value at $191.4 million; however, the thriving DC office market, the property's highly desirable location between the White House and the US Capitol and its stellar tenancy--1001 Pennsylvania is 99% occupied, with leading law firm Crowell & Moring LLP leasing 336,000 sf or 42% of the building through April 2015--undoubtedly contributed to the sale price.

Occupying an entire two-acre city block, 1001 Pennsylvania Ave. is surrounded by such prominent District structures as the FBI Headquarters, the Old Post Office Pavilion and the Ronald Reagan Building. The 14-story tower with the limestone facade was designed by the architectural firm of Hartman Cox and reached completion in 1987.

In addition to its class A office space, the premiere structure also features 41,000 sf of ground-level retail, as well as a three-level underground parking facility. Other office tenants include private equity firm the Carlyle Group, and law firms Dorsey & Whitney LLP and Fried, Frank, Harris, Shriver & Jacobson. Retail tenants range from Bank of America to the TenPenh restaurant.
