Here is my most recent build - Willis or Sears Tower from Chicago in my traditional 1/3 scale! There is still a lobby to complete, which will be added in the next update. It was built in 1.16.5 so works with that and higher versions. I used Greenfield Texture Pack and Chocapic 13 V8 Ultra shader for the pictures. Enjoy)

Tower dimensions:
Height:
  -roof: 147 blocks
  -highest antenna: 177 blocks
Base: 21x21 blocks
