So, I noticed a site plan was posted to the AULCC page, and it's listed as "The Standard at Austin II".
I assumed at first that it was a typo for the site plan for The Standard at Austin. The site map in the site plan does show the location as being the southeast corner of West 23rd & Pearl Streets, which is the location of The Standard at Austin. However, it lists the address as 801 West 24th Street, which is the location of the University Towers.
Also, if you look at the building elevations, which start on page 17, it shows the West 23rd Street elevation as being the south elevation. That could only be the case if the building were north of 23rd Street, which just so happens to be where the University Towers is.
So now we know why the University Towers' garage was demolished last weekend and why there's a demolition permit for the University Towers.
This new building doesn't appear to be an exact twin to the first one, but they will be similar.
The elevations show the main roof as being 174 feet 8 inches, but I measured the mechanical penthouse as being approximately another 10 feet beyond that, so rounding up it would be around 185 feet to the mechanical roof.
