The per-sf figure rises head and shoulders above the average sale price for class A office buildings in the District, which was $382.26 in 2003, and $410.40 in the first quarter of this year, according to Advantis Real Estate Services Co.'s First Quarter 2004 Office Market Report. CB Richard Ellis had originally marketed the property on behalf of the seller for $5.2 million.

A onetime residence of Theodore Roosevelt, 1215 19th St. sits at the corner of Jefferson Place and 19th St., just south of the trendy business and residential neighborhood of Dupont Circle. The historic four-story rowhouse was originally developed in 1885, but has since undergone a series of alterations, the most significant of which occurred in 1957 when the building was converted from a residence to an office property. The last major renovation took place in 1984 when the owners facilitated a makeover and an expansion that resulted in a new conference facility and multimedia room. According to District records, the property's current assessed value is approximately $3 million.

"The new owner is using the building for its own business purpose; it relocated from another building downtown," Transwestern's Donald McCully tells GlobeSt.com. McCully and colleague Gerry Trainor represented Roosevelt Land in orchestrating the deal.

In addition to its prime location and status as an historic property, the architecture and aesthetic of the building likely contributed to the grand sale price. "It is truly a classic piece of real estate," McCully adds. "It is a very unique piece of owner/occupant real estate."
