In Riehen, the federal building register lists 4'255 residential buildings and 10'905 dwellings. These municipal benchmarks help put your home in context, but do not replace an individual assessment.
73 % built before 1980
Construction year does not reveal past renovations: check the current insulation condition.
38 % · District heating
This distribution describes recorded buildings, not your system's consumption or efficiency.
For renovation planning in Riehen, RegBL figures reveal that 1031 out of 4255 buildings are under heritage protection. If your property is classified, you must contact the municipality early to navigate permit requirements. Regarding house volume, data coverage is partial; the standard SIA 416 volume measurement is not recorded for the 2885 houses listed, complicating the assessment of scale for insulation or heating projects. Additionally, the year of last renovation is not available in the registry. Homeowners should account for these missing metrics when estimating project costs and technical specifications for their specific building.
