Article lists 5 recent buildings in Washington, D.C. that are to regret, and either be renovated or demolished- including apostate Nationals Stadium
Both of these structures are serviceable, but convention centers and stadiums are designed around the latest technologies and ways to steer patrons to beer stands and merch. They usually have a short shelf life. Chances are both of these buildings will be renovated or replaced.
The other four such structures to regret that this article lists are the D.C. Convention Center, the ATF Headquarters, an apartment building with a Safeway supermarket "The Exchange" at Wheaton Place, and the underground U.S. Capitol Visitor's Center.
Of these, IMHO, the ATF is the ugliest, and the National's Stadium is the most mis-located.
