What you see here is 100 crates used for Evian water. The dome shape is created by placing Evian bottles between the crates. I think the spikey things coming out of the dome are plastic ties holding the whole thing together.
This is the creation of Alexander Clos. It is a “temporary living concept”. Quite clever. Though I’m not sure how much this thing will help when it rains. I guess that’s why it’s a “concept”.
