Renovations, heritage and volumes

For your renovation plans in Richterswil, the official building register provides useful insights, though coverage remains partial. With a median building volume of 1103 m3 according to the SIA 416 standard for the eight measured structures, this figure helps you gauge the scale required for heating or insulation upgrades. Given that these metrics represent only a small fraction of the total housing stock, they should serve as an initial guideline rather than a definitive assessment. We recommend conducting a professional on-site evaluation to determine your specific project requirements accurately before proceeding with your renovation budget.
