The "Casita de Papel" has a length of 5.19 m and a width of 4.15 m. The floor is divided into two to allow the passage of visitors, to the level of + 4.00. From there, it¨s geometry is governed by the typical gable roof, reaching 7.00 m. Inside, four vertical walls are housed in a blade form, of which their function is to expose different types of pottery.

Windmill's mission was to verify the structural elements that compose the paper house. The "Casita de Papel" is made of pressed cardboard tubes, joined together by turned  beech wood parts and inside it contains four ceramic walls to stabilize the whole piece.

Note the difficulty of bracing the structure with elements that go unnoticed to the naked eye, such as strategic placement of cables between the planes forming the cardboard tubes. In the calculation, we also took into account the possible thrust of visitors and imperfections caused by assembly.
