Wow, very cool. Thanks for the PM, Mopacs. Not sure on the height, but they look to be around 180 to 200 feet tall. Tower of the Hills adjacent to these is around ~140 feet tall and is just 10 floors. I know there's no height restrictions in that area due to the airport or any other problems. That huge water tower along 183 next to that car dealership just down the street is the Pond Springs Water Tank. That water tower is 215 feet tall according to one source. So something in the area of 200 feet is definitely not out of the question there.
So I guess Tower of the Hills is represented there in the lower left near 183. This is interesting.
As for their design, they're ok. Their facades could use a little dressing up, but I like the roof idea. I wonder if the pyramidal roof will be glass or stone/metal? I hope it's glass.
At this point these would be the tallest outside of downtown, UT Campus, and West Campus/The Drag areas. Of course to be technical, they'll have TWELVE Domain to contend with, which ever is built first will get the title.
