On the horizon
Mathias Klotz has created some fine examples of architecture in concrete. While outwardly different, many of his buildings display threads of continuity. One such is his repeated use of a raised linear bar defining a strong horizontal datum against a sloping site, forming a new horizon against which the site can be registered. In his Viejo House in Santiago he handles the weight, roughness and plasticity of concrete in a fresh manner but still brings a sense of mass and gravity that is absent in his other work.Further examples of his work are found in Mathias Klotz (2G S. ), published by Gustavo Gili, £19.50.
