Linings of perimeter masonry made of ceramic blocks POROTHERM 30 Profi, based on concrete feet. The inner supporting masonry is made up of porotherm 25 AKU blocks. The inner non-supporting masonry is designed from POROTHERM 14 Profi blocks and POROTHERM 8 blocks. The insulation of the building is designed as a certified contact system. The horizontal supporting structure of the ceiling is solved by a cross reinforced ŽB plate. The staircases are ŽB monolithic. Roof structures are made up of flat roofs.
