Renovations, heritage and volumes

For your renovation plans in Herisau, the official register indicates that three buildings are under heritage protection, requiring you to contact the municipality early to navigate permit requirements. Please note that data coverage for this figure is partial. Regarding building volume, the 1736 recorded houses lack measured data according to the SIA 416 standard, making it harder to estimate the scale of heating or insulation works based on these records alone. We strongly recommend consulting local experts to assess the specific technical requirements and dimensions of your property before finalizing your renovation budget and timeline.
