Renovations, heritage and volumes

For homeowners planning renovations in Würenlos, the RegBL data provides critical context. Regarding heritage protection, 264 out of 1367 known buildings are officially protected, necessitating early contact with the municipality to clarify permit requirements. Data coverage remains partial in other areas: information on the renovation year is unavailable for all 1479 buildings. Furthermore, the volume of 1094 houses is documented without reference to the SIA 416 standard. Consequently, assessing the scale of insulation or heating works is less straightforward, and homeowners should consult technical experts to determine accurate requirements given the absence of median volume figures.
