And some before-and-nows show that the eventual new block of I Street between 2nd and New Jersey is starting to be more than just a dream:

If you haven't been following along, this site spent much of the 1900s as a trash transfer station, before the DC Department of Public Works turned it into an operations area for heavy trucks and plows. The block to the north is going to be developed by William C. Smith, starting with the Park Chelsea apartment building, once some deep (deep!) utilities running below the site get relocated. The block between I and K is part of the Capper/Carrollsburg Hope VI redevelopment footprint, and is slated to eventually have a large mixed-income apartment building, though no announcements have been made of when that might actually happen.

I think it's also now safe to declare it Demolished Building #170 since 2003.

If you're already missing the trash transfer station {snort}, here's my galleries from back in June of its interior and exterior, as pre-demolition abatement was underway.
