In dense urban areas, an increasingly frequent assignment of architects is likely to be to put existing buildings to new uses, or, in another way of looking at things, to bring them up to the technological level of today’s requirements. Sometimes, too, re-design is resorted to, from the point of view of the materials and design of dilapidated sixties and seventies façades. The whole diapason of this topic is covered by the assignment to repair and revitalise parts of the textile college in Klagenfurt confided to the Carinthian/Swiss team of Sonja Gasparin and Beny Meier. The school complex in the neighbourhood of Klagenfurt Fair is a conglomeration of buildings from various periods, from the 1900s to the 70s, with the current interventions relating to three buildings on the western side of the complex. The two buildings from the 70s and one from the 50s had to be put to rights from the point of view of both services and construction.
