El Maadi Residential Tower 18
https://skyscraperpage.com/cities/?buildingID=3493
El Maadi Residential complex seems to only have five 140 m tall towers (Google Maps). There is no reference that a Tower 18 exists.
This site (
http://www.azmyarchitects.com/archit...ml#prettyPhoto) offers a short description of the Master Plan, which speaks of seven 140 m towers.
Looking at the site on Google Maps there are two squares that corresponds with the Master Plans additional two intended but unbuilt towers.
So I guess the status of Tower 18 can be marked as
cancelled.
