Days four and five of the Brick Works Thin-Tile Vault Seminar – both days on the site at the Valldaura Self Sufficient Labs – kicked off with a collective effort to finish mounting the Laser-cut cardboard pieces that were used as guides for the construction process. These were attached to the wooden formwork. The steel frame and foundations were then set, and the cardboard guides removed, to give way to the beginning of the brick laying phase. Thin bricks are starting to be laid, held in place with the help of the steel rod structure, and fast setting concrete. Once the first layer of bricks is in place, the metal substructure will be removed, and two more layers of bricks will be placed, finally leading to the completion of the structure in question.
