The interesting cases identified in this Building Mistake Quartet allow for a more playful approach to a serious subject. The contents are not exactly amusing, particularly if one or the other of your projects conform to the case studies. Nonetheless the Building Mistake Quartet conducts the lay person in an exemplary fashion directly into the subject: the building defects are depicted on cards, with text that describes and evaluates the problem, as well as specifying the costs to correct the problem. The cases are rounded off with a telling explanation by the relevant builder.

Most building clients have their own stories to tell about building mistakes. They delay completion, are the visible proof of sloppy work and cast a bad light on the honor of craftsmanship. And they often have negative health consequences. Mistakes come in many forms: the electrical socket behind the radiator, foam insulation oozing over the door frame or the drooping ceiling. The author of the following booklets, an architect – was confronted repeatedly with work mistakes, which he collected for his own use in a data bank. After gathering more than 400 different mistakes in a short period of time, he decided to make this knowledge publically accessible.
