Renovations, heritage and volumes

For homeowners planning renovations in Goldach, official register data shows that 27 buildings out of 1 561 are under heritage protection, while the status remains unknown for 1 456 others. It is essential to contact the municipality early regarding permits to avoid complications. Furthermore, data coverage is partial for building volume according to the SIA 416 standard, with 991 houses having unknown or non-standardized measurements. This lack of specific volume data makes it more difficult to accurately determine the scale required for comprehensive insulation or heating renovation projects, so professional on-site verification is highly recommended for your planning.
