The Amertec building was built in 1967 by Chayo Frank, an architect who built this weird looking monster for his family's woodworking business which operated until 2002. Since then the building has sat abandoned, however apparently the word is that a produce company is using it for storage but this has not been confirmed. The inside has been photographed by UrbExers that actually got inside. Since I do not believe in posting others photos on my site you can visit Curbed Miami or AbandonedFL.com to see more photos. You can also visit ChayoFrank.com, the architect.
