I just happened across this list,too.  I think it should be deleted.  As it looks like that is unlikely to happen from the above comment, I am going to update the list.  I will do it based on today's date.  It will be continually out of date in the future as there are hundreds of proposed towers over 300 meters.  I suggest that to make this list complete there need to be a few criteria set: 1) only complete, open and in-use towers 2) height must be as certified by the Council on Tall Buildings and Urban Habitat or as by the measuring standards of it's height committee 3) towers should be broken down into groups 300M+, 600M+ and this will allow for the continual use of the list as it gets too large in the new future and only the taller category is updated 4) only the concept architecture firm to be listed, no local architect, no architect of record, disputes should refer to whoever the developer chooses or a majority of authorities on the subject, like CTBUH, Emporis, etc 5) as for the listed person, oh boy this is always an argument only sometimes is it clear, any suggestions? -
