Conthey's housing stock in figures

The federal building register lists 3'186 residential buildings with 5'707 dwellings in Conthey. 59% were built before 1980, before serious insulation standards, and 34% are still heated with oil or gas.

Only 4.4% of residential buildings in Conthey report a solar thermal system in the register, so most roofs are still free. Photovoltaics are not recorded there; check the solar cadastre for your roof.

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.

These figures serve as a foundational guide for estimating your upcoming project requirements.
