For Act #3 Highrise (Surveillance), artists Yeb Wiersma and Lotte Geeven tried to legally claim the airspace above their territory as far as the human eye can see on a clear day (38.7 kilometres) around West, to donate it to the inhabitants and all that passes through. A report was made to prepare the case. This paper includes the voice of the inhabitants, governmental institutions, law firms, specialists on intangibles like clouds and wind and finally biologists about the birds passing through the air space. The case is be parsley built around the philosophy of ownership.
