Renovations, heritage and volumes

When planning renovations in Thal, it is essential to consider the RegBL data: 17 buildings are officially heritage-protected, meaning you should contact the municipality early to clarify permit requirements. The median building volume of 963 m3 helps you estimate the scale of necessary heating or insulation upgrades. Please be aware that data coverage is partial, as volumes measured according to the SIA 416 standard are only available for 23 out of 1262 houses. These figures provide a useful framework for your project, ensuring you align your renovation plans with both local heritage regulations and the physical scale of your home.
