I previously proposed a minifig scale version of the towers, but found out quickly that it would be too massive a model to be made, so now I am proposing The World Trade Center complex (World Trade 1-7) to be made as part of Lego's Architecture theme. The scale would be more feasible, not to mention more affordable. What I have modeled so far are the towers only, as my LDD build is still a work in progress. I will be keeping this project updated as I add to it. I am not listing how many pieces are in this yet, as, like I stated earlier, this is still a work in progress.
Here you can see the courtyard, with the famous golden sculpture included.
