Many half-timbered buildings that have withstood the elements for centuries often only become candidates for renovation through modernization or repair measures. Are historic half-timbered houses compatible with modern living comfort? How can today's requirements be met without damaging the historical substance? Wolfgang Lenze explains the structural and physical characteristics of a half-timbered house, identifies the most common mistakes in maintenance and renovation, and provides concrete guidance for sustainable restoration based on historical foundations. He outlines precise procedures, construction features, materials, and formulations that are based on traditional craftsmanship techniques while also considering experiences with newly developed products, for example in the areas of insulation materials, clay construction, window systems, or painting systems.
