The General Services Administration's (GSA) West Heating Plant auction finally ended Wednesday, more than two week after the soft close date, with a winning bid of $19.5 million.

The opening bid for the 2-acre lot and 20,000 square-foot building at 29th and K Streets, NW was $500,001. Though the auction opened Jan. 18, the first bid did not appear until Feb. 14.

The soft close for the auction was 5 p.m. on Feb. 19, but the auction was set up to not officially end until 24 hours went by without a new bid. The last unchallenged bid came in Tuesday and the alotted 24 hours expired mid-day Wednesday.

Bidding was anonymous and the winner, Anonymous Bidder #2, is unknown.

The GSA previously said it would release the identity of the winner after the auction closed.

Editor's Note: The headline was changed to remove the word "Sells" because the property is not officially sold. The GSA is still finalizing the auction now that it has closed.
