Usually I prefer to work on site by interfering with already existing structures.
As I came there first, that's what I found: endless meadow, trees and blue sky.
Not exactly what I play with usually.
So I decided to cut open the idyll, and pretend there is no endless meadow, but only rooftop-gardens of the disgust underneath ...
8 exhausting days of hard work (at least for people who usually cut paper only).
