The office architecture of the 1970s and 1980s makes up a large part of Dutch office building stock, at about 30%. Most buildings are now in need of major renovation and often no longer correspond to today's aesthetic perception. In addition, the function of the buildings must be adapted to today's needs and technological standards. This is not least due to the rapidly changing world of work, especially after the climax of the Corona pandemic. In order to prevent the possible destruction of buildings or building parts with a potential to become protected heritage, this master project offers a first approach to collecting characteristics of this period for heritage and sustainability reasons. A focus is placed on those that lend themselves to a particularly sustainable strategy, as the study shows that the early sustainability movement of the 1970s also left its mark on the construction methods of the time. The results together with the results of a value assessment are applied to the adaptive re-design of the police building in the Mathildelaan in Eindhoven. Further, aspects with a particular sustainability perspective are incorporated in an extension. In this way, the existing building is integrated into a modern urban context.

DIN 18 024 and 18 025, published in Germany in the 1970s, were among the first standards in Europe on the subject of accessibility in the built environment. The paper describes their historical context, reception and their effects on literature and practice.
