Renovations, heritage and volumes

For renovation projects in Windisch, the federal building register (RegBL) identifies 260 out of 1270 buildings as protected heritage sites. If your property is classified, you must consult the municipality early regarding permits. Regarding building volume, data is partial as no values following the SIA 416 standard are available for the 837 residential buildings recorded. Furthermore, no data exists regarding the year of renovation for the 1270 buildings in this municipality. Due to these gaps in the register, homeowners should obtain specific building assessments independently to ensure accurate planning for their energy or structural upgrades.
