Renovations, heritage and volumes

For renovation planning in Conthey, RegBL figures provide vital context for homeowners. With 25 buildings identified as heritage-protected out of 1230 known, consulting the municipality early regarding permits is essential. The median house volume is 747 m3 per SIA 416 standards, helping you gauge the scale of necessary heating or insulation upgrades. Please note that data coverage is partial: volume measurements are only available for 116 out of 2439 houses, and specific records regarding the year of renovation are currently not available. These figures serve as a foundational guide for estimating your upcoming project requirements.

Tips before you start

  • In condominiums, the assembly decides and the renovation fund often pays.
  • Plan fire-safety requirements (doors, emergency lighting) early.
  • Phasing floor by floor keeps the building occupied during works.
