you could but most of these architect renderings don't look like they have any of that. Some of them are communal terraces with deep infrastructure for trees to grow down into. But a few of these renderings are smaller terraces and judging from the rendering just 30-50cm of structure above the apartment below. Except grass not much can grow there. I've seen some pullt it off fairly well. Like the Sands Marina Bay Hotel in Singapore. In real life it looks like it does in the renderings before groundbreaking.
