In the past the demands resulting from saving of energy have been lead to an enormous development in masonry constituents and in masonry building in general. The labour costs and the requirements of employer’s liability insurance influenced this with respect to the efficiency of erection and assembly. The paper presents the results of product developments in the past and in the present time. It also shows the needs of future attempts to guarantee the survival of masonry as a building material with a long historical tradition. Beneficial performances under the aspect of sustainability and preservation of the nature for next generations will be shown. For that it is necessary to give the theme of sustainable construction a whole more importance in future product and system developments under the forecast of shortage of fossil resources. This includes also the view on the whole life cycle of a building, from the beginning of production of constituents and assembly of it to buildings over the time of utilisation till the end of life with the recirculation of the remains. Some important points for the future development of masonry under the umbrella of sustainability were accentuated.
