A building is considered to have become a ruin when its windows or doors are no longer intact or when walls or roofs have holes. When this happens, the building is exposed to the weather, to wind and rain or to wildlife and vegetation. The building is no longer protected from exterior elements, nature invades setting off a process of the merging of building and nature. A building in ruins also displays the materials it was built from, its construction method, so that it reminds of what it must have been like when it was being built, when the place was still a building site. This artwork is part of a homonymous project, which was materialised in the book Ruins In The Netherlands XIX - XXI, published by Jap Sam Books.
