There are a few "classy" tall housing buildings in the 13th, but they are not on the Olympiades patch we can see here, closer to the 5th district, like the "plein ciel" building, with a roofed poil as well as an open sky pool both at the top of the building.
I like being in the upper levels of a building, but not something that depart from the classic Paris skyline.
As an experiment, the Olympiades is not such a failure mostly thanks to the asian community that holds it together. Doesnt look great but you dont feel weird walking around that neighborhood.
