National Science Foundation headquarters site is sold

The new site of the National Science Foundation headquarters in Alexandria has been sold to San Antonio-based USAA Real Estate Co.

The 2.03-acre development site is in the Hoffman Town Center, a project owned by the Hoffman family.

Financial details of the sale were not disclosed. The deal was announced by the seller's representative, Newmark Grubb Knight Frank, a commercial real estate advisory firm.

The 704,571-square-foot National Science Foundation (NSF) building will include two interconnected towers, of 19 and 14 stories, respectively, plus 375 parking spaces on three underground levels and 19,437 square feet of retail space.

The NSF will occupy 94 percent of the building and has preleased it for 15 years through the General Services Administration. The property is expected to be completed in late 2016.

USAA plans to seek LEED Silver Commercial Interiors Certification for the building. The company has hired Los Angeles-based Lowe Enterprises to handle development of the building and assume management responsibilities when it is completed.

Hoffman Town Center occupies more than 56 acres next to the Eisenhower Avenue Metro Station in Alexandria’s Carlyle neighborhood.

When completed in 2020, the center will include 3.5 million square feet of Class A office space in 10 buildings; 1.5 million square feet of housing in four residential towers; two full-service hotels; 220,000 square feet of retail stores and restaurants; and a 22-screen AMC Theater.
