Nominate your 3 favorite skyscrapers that have never been built for the Unbuilt Cup

In order to find out what skyscraper that has never been built is our favorite one, please all nominate your favorite unbuilt skyscrapers. The most nominated skyscrapers will be lined up in the Unbuilt Cup tournament.

rules: you can nominate up to 3 skyscrapers for this cup. Nominees must have been actual projects at some point, so please don't nominate functional buildings. Feel free to add images to inspire others, but please do not use this thread for discussion.

Thanks to jome_omt for suggesting this.

Happy nominating!
