Here's my November 2017 list of Austin's tallest projects that are at least 150' tall or appear to have at least one building 150' tall or more based on available information. Two more buildings have been added to the list for the December update.
There are five status types:
U/C - Cement has been poured
Site Prep - Dirt is moving or utility work is underway
Site Demo - At least one structure on the site has been or is being demolished
Proposed - The project has been announced and/or had building permits filed
Planned - Less information is available than a proposed project, more visionary
Projects highlighted in green are underway with financing/funding in place. This can include projects with a status other than "U/C".
Projects highlighted in yellow have been completed during the current calendar year, and have been removed from the project count.
Several of these projects are stale. But I keep them on the list unless either a new proposal for the site is made or the developer sells the site without an approved site plan.
