In all honestly, I'd bank on China Contructions CCCC tower to be built. They have a great track record. Along with Skyrise, Miami Central Phase II, and Brickell Phase III. I think these have the best chance of happening.
I'm a little pessimistic about the prospects of 255 East Flager (volatile parcel) and the rest.
One Bayfront has been a while in the making, and idk if they ever will rise.
The rest could rise, but they better do it quickly before the market craps out. If it doesn't, they all have a good chance of happening, but most of them could easily get axed if the market crashes so we are gambling on these.
But I hope they all rise, and at their height and not some downgrade.
If that happens, Miami would be number two in super talls. Quite impressive for a city with a city limit population of less than 600k.
What I could see happening if the market isn't favorable is that many of these will be redesigned and be in the 600 - 700 foot range. Not the first time that its happened, but being the optimist that I am, I hope I'm wrong.
