The Downtown Austin Blog says the site plan shows it at 20 floors now and exceeding 344 feet. That height seems too tall for a 20-story office building. I'm thinking the actual height is 244 feet and the elevation is showing the ground elevation as "100 feet" instead of 0 which some elevations do sometimes. Still a 244+ foot tall building on that lot will be some nice infill.
