In this photo from
bioreconstruct (@bioreconstruct) | Twitter there are planters, balconies or at least double walls on the side of the queue building (in this photo on the left side).
Does anyone know what it is for?
On the front side of the same queue building there are 2 double doors (I expect for emergency access and/or maintenance but also 2 smaller doors (on the left and right side of one of the large doors). Has anyone a clue why they are there?
Also what is all that metal on the bottom of the picture for?
