So I contacted the people with the planetarium and got some wonderful news!
The proposed height is 655 feet
. So that will put 33' taller than the roof of the Austonian and only 28' shorter than the Austonian spire, and 182' taller than the roof on the 360 and 74' taller than the top of the 360's spire. So it would be a new tallest for Austin! Which would make our 3 tallest residential. But since it is higher up in elevation I imagine that it will look even taller than the Austonian. Probably by like 50 feet or so.
Also, they might add more to the top. One idea they have is to add a restaurant with an observation deck to the top with elevators on the outside to reach it.
And if anyone wants to know more about it, every month they have a Southern Skies Social
where they get together at House Wine in South Austin
(408 Josephine Street at Barton Springs and S Lamar). It is the last Wednesday of every month (this Wed!!!) from 5 to 9pm
and the bar donates 10% of its proceeds to the planetarium. They will be discussing all sorts of stuff from the building to the planetarium to space stuff too.
They asked me to ask all of y'all Skyscraper enthusiast to come and tell them what you like or don't like about it this Wednesday.
Also they have a fundraiser every second Tuesday at Opal Divine's on Mopac and Parmer if you can't make it on Wednesdays or if South Austin is scary to anyone.
