The building was built first, then the excavation for the parking garage started. Canal and rain soaked earth on one side and a void on the other. Nature stepped in.
how would you like to be living in one of the other sister buildings? lol...I think they tore them all down but don't remember
My first thought was, what kind of idiot doesn’t excavate for the parking garage and then build up from there. The link supplied by rolling stone has lots of interesting info.
