The decision follows years of failed attempts by federal officials to persuade Congress to fully back a plan for a campus in the Washington suburbs paid for by trading away the Hoover Building to a real estate developer and putting up nearly $2 billion in taxpayer funds to cover the remaining cost. For years, FBI officials have raised alarms that the decrepit conditions at Hoover constitute serious security concerns. — The Washington Post

Built in 1975 in Washington DC, at $126 million, J. Edgar Hoover Building was the most expensive federal building ever erected. While much loved by some architectural critics, the building has also been under intense criticism for its appearance and functionality ever since its construction.

Some of its most distinctive features like its open courtyard, designed to allow visitors to walk freely into the inner courtyard, and its firing range equipped with a 162-seat auditorium, where visitors can sit and watch agents take shooting practice, have become obsolete over the years. The Stanislaw Gladych and Carter Manny-designed Brutalist icon was going to be demolished and replaced with a mixed-use condo building, but as of now, it's destiny is unclear.

According to the Washington Post, "Further retrofitting is prohibitively expensive; despite the Hoover building’s overall size of 2.4 million gross square feet only 53 percent of that is usable according to a 2011 report from the Government Accountability Office."
