I also invite everyone here in the forum to post their questions about planning and construction of skyscrapers in this topic:
Perhaps oh I as a historian can answer one or the other question.
And another comment to you @lowkeylion , I have created a separate topic about my Megatall concept titled Sky High Towers. These Twin Towers would be the tallest Twins in the world with a total height of over 2200 feet. This is just one concept of many I have.
Enough off-topic writing let’s get back to the real topic of 1E 57th Street, maybe we will see a similar rendering to the Rolex building here.
