The building is designed in Laser-Cut + technology. This means that the edges of the walls are cut at an angle of 45 to mitre & thus can easily be folded & stuck together. Another highlight of the Laser-Cut kits: All roofs are intricately laser-carved, in order thus to be able to guarantee their highly realistic appearance. Each kit is accompanied by the required special adhesive as well as also rain pipes & fall pipes made from plastic.
