Lehmputze (clay plasters) are natural wall finishes made from clay, sand, and fibres, applied directly onto masonry or clay blocks. Because they are unfired, their production requires very little energy, giving them a significantly lower embodied carbon footprint than cement- or gypsum-based plasters. They are vapour-permeable and hygroscopic, helping to regulate indoor humidity and improve air quality, while their thermal mass contributes to stabilising interior temperatures. Clay plasters are non-toxic, fully recyclable, and can be reworked or reapplied without waste, making them a circular building material with long-term ecological benefits.
Applied as sustainable solution
Haus Giebel In Brandenburg, Germany, Peter Grundmann Architekten has completed Haus Giebel, the conversion of an old settler’s house into an open, multi-layered family home. The modest dwelling belongs to the early 20th-century tradition of German Siedlerhäuser — simple, elongated houses built for working families and often extended over time.
