Owners of a monumental building in Beverwijk suffered from unwanted visitors. They gained access to the roof via the spiral staircase and caused a lot of damage. Anton Constructiewerken was asked to close the stairs. We did this by placing an access gate. In addition, we have closed the steps with perforated sheets.
