If #Europe desires to increase #GNP, I believe it will have to forego the limitation on building max heights and eventually create more skyscrapers in their central districts.
If you zoom out and look at all other world biz districts around the world, a critical density creates something akin to a human ‘chain reaction’ of interactions when people are at a certain proximity.
While it is expensive to do so, there is an organic reason for why many other cities around the world have been built upwards. To facilitate this density.
The challenge to architects in these cities, will be to preserve while also growing.
