Renovations, heritage and volumes

For renovation projects in Lachen, official building register data provides key insights for your planning. With only one protected heritage site among 217 known buildings, heritage restrictions are limited, though contacting the municipality early is always advisable. The median building volume is 975 m3, which serves as a helpful reference for scaling heating and insulation works. Please note that data coverage is partial, as volume measurements according to the SIA 416 standard are available for only two houses. Consequently, homeowners should consult local experts to ensure their specific renovation budget aligns accurately with their property's unique dimensions.
