Nice find, Hill Country. I'm guessing it's probably around 250 feet or so judging by Austin Skyhouse. At that height if it were complete today, it would be Austin's 36th tallest building.

I checked one of the backup links (linked above), and it has some clearer versions of the images from the video.
That link also says the grocery store will be a Fresh Plus (the owner of the grocer says so).
