New plans have been filed with the city that show the building elevations. Bottom of this link:

The building elevations also do a good job of showing what the building will look like. They're planning to have 4 flagpoles on the mechanical roof facing Lavaca Street that will become the highest flying flags in Austin.
The first height we saw came from a conceptual plan that only showed the number of floors and not the design. That height was 295 feet to the mechanical roof.
This one is much more detailed and most recent.
The heights are:
329 feet 11 inches to the top of the 4 flagpoles.
305 feet 2 inches to the mechanical roof. (the official architectural height).
284 feet 11 inches to the main roof.
269 feet 7 inches to 24th floor (top floor).
269 feet 7 inches to 24th floor setback.
88 feet 10 3/8 inches to podium roof/hotel amenity deck.
Since this building will have a hotel and residential, there will be two pools. The hotel pool is on the 7th floor while the residence pool is on the 24th floor setback.
The south elevations also show that they are planning to incorporate the Gingerman/Ghost Room facade in the design. I think this will turn out to be a nice building. It looks like they're planning to pay attention to detail. If this building was completed today it would be the 25th tallest building in Austin.
