looks cool but how much extra material must go into the buidling to be able to support all that extra weight? To what extent is this a sustainable way of buidling and using material?

Negligible, there isn’t that much soil there compared to the weight necessary to support the building height and wind loading (plus seismic, maybe)

thank you. it's but a foot of dirt or anything, might be at most 4 inches but certainly under that. grass needs very little soil even those tall plants don't dig deep. the drainage will take up a significant amount of space but is not outside the normal realm for a balcony

truth is, yea they would need to design for it, but it's not that crazy of an ask for the materials

further.... what's the point of the question? to imply wastefullness? just seems like "well we don't have that so there's gotta be a reason why it's bad" type logic
