Renovations, heritage and volumes

For your renovation plans in Grabs, please note that the federal building register data is currently partial. With a median house volume of 776 m3 calculated from a sample of 30 buildings based on the SIA 416 standard, these figures provide a baseline for estimating the scale of your heating or insulation upgrades. As the register covers 2120 buildings, please be aware that information regarding renovation years is unavailable and no properties are recorded as protected heritage sites. Consequently, you should rely on professional on-site assessments for these specific aspects while using the volume data as a reference.
