Buried in leasing plans revealed yesterday on exMiami is this little kernel of big fat news: MiamiCentral is planning a one million square foot 'superpower' on the block directly south of the station, in addition to the other towers of the project. It will be a combination of offices, hotel, and residences. Yes, we knew they were doing a big tower, but ay dios mio. No word yet on how many floors this thing will be, although it's a safe bet that the Federal Aviation Administration is going to have some finger wagging to do. In other All Aboard Florida news, there are two new renderings that little annex they're building in Overtown. Check 'em out, after the jump.
