A massing diagram for the Old Convention Center site showing a great deal of detail regarding its usage and scope.
The highlights include:
24 story Office building (includes 8 parking levels)
25 story apartment building (includes 6 parking levels)
National Museum of African American Music
High end retail
Mention of a 'House of Blues'
'Creative space'
I would estimate the towers to be a little over 300' tall each.
As noted in a previous post, agreements have been reached with all parties and City approval should be forthcoming.
