The inventory of the damages was worked out by a commitee, and it is an appendix to this paper. The main walls of the building made of full brick of 7,5 MPa class and mortar of 0,15 MPa class were damaged and lowered their technical value caused by long-time action of water and lack of vertical and horizontal insulation. Ouside and inside plaster are settling from base in many points. The PVC tile floor was destroyed together with base and thermal isolation layer. The millboard and wooden partitions were also destroyed. Wall paper in many rooms is settling fron the base.
