Renovations, heritage and volumes
For your renovation projects in Bernex, the federal building registry data shows partial coverage. Although the register lists 1611 buildings, specific details regarding renovation years, heritage protection status, and building volumes based on the SIA 416 standard are not currently recorded or available in our system. Due to this lack of specific RegBL figures, property owners should communicate directly with the local municipal authorities to obtain precise information about their property before starting any major work. Early coordination with the municipality ensures that you address all relevant planning requirements and local building regulations for your renovation project.
