Briefly, Cochise brought this pic to SSC.
There you can spot Aurore and have a comprehensive view of the configuration around. This is all built upon the madly large deck of la Défense. I'd forgotten the Manhattan tower right behind Aurore in my previous comment, cause it's slightly larger than the 4 I mentioned and differently shaped, but not any taller. So it's actually 5 100m-tall buildings in a row you get there. I say that's too many. This picture shows the positive impact of Air² over the area. The lowrises right between the esplanade and the taller buildings are residential, so I eventually changed my opinion about them. They don't necessarily have to be torn down. But I'd like the local community to help the inhabitants to really improve them somehow. Some shinier facades with more attracitve commercial spaces on 1st floors would be perfect.
