Well,to make it all clear for what you just there for what they do good,then well as I can see so far with the kinda decent good descriptions of yours, then one of them have already been kept, and that is the high quality of the façade, i.e the materials they used. But, yeah it aren't very modern(aka. top modern/ or high-tech btw ..OR neo-futuristic and that's aka. hyper modern. Just fyi), BUT merely modern..I usually like much most of the projects in Paris, but those mid-rises are really just a stack of crap, no harmony and really ugly for some of them, the worst that french modern architecture can do... Either you do something sober and classy, with ordinary shapes and nice materials, or you do something very modern but high quality. Not this...
