The  were completed in 2007 in Hangzhou, China. These apartments remind me of a neatly organized game of Jenga- the way they “sweep” outwards looks like every apartment is stacked on top of another. Each second floor there is a courtyard that extends to two floors up, so each resident can have their very own and feel as if they are lower to the ground than they really are. There is also greenery on the rooftop. I love this concept because it can make residents of a packed city feel a little less crowded and condensed.
