In this research, the use of the light earth construction method is assessed on its possibilities to be implemented in existing building systems, especially its compatibility with futureproof timber construction, while meeting contemporary housing requirements. Combining clay and fibres in various proportions will achieve different technical properties, that can be applied in diverse building elements, to reach futureproof housing requirements. In the Netherlands, clay is available, and a sustainable approach involves reusing excavated soil to avoid overexploitation. The interaction of building elements in timber structures can lead to hybrid systems. Light earth, traditionally an infill for timber frames, can potentially be applied to various timber systems.
