For the baseball fans who arrived every spring, 1015 Half Street SE was an unfortunate symbol of the real estate collapse in Washington.

Begun by a company that went into liquidation shortly thereafter, construction stalled during the recession, leaving a skeleton standing at the corner of Half and L streets in Southeast D.C.

The building was finally completed by another company, but by that point many organizations were cutting back on new space requirements. Other buildings filled up with companies but all 10 floors of 1015 Half Street remained empty for more than two years — a long time in the go-go Washington real estate market.

Now the building has landed one lease and is close to another.

The National Labor Relations Board plans to take 143,116 square feet in the building beginning in December of 2014, according to an announcement from the government, and CBS Radio plans to lease more than 30,000 square feet there, including some ground floor space, according to sources familiar with the deal who declined to be named because it has not been finalized. CBS Radio did not immediately return a request for comment.

NLRB will be leaving its current digs at 14th and L streets NW and the federal government says it expects to save $4.2 million annually compared to their current lease.
