Many flats in Cerdanyola del Vallès still have old panels.
Cerdanyola del Vallès has a building mix shaped by its university-town role: 1970s–80s flats in Centre and Banús let frequently to lecturers and students, which drives high demand for quick repairs between tenants. In Cerdanyola Nord and Bellaterra semi-detached homes with shared pools dominate. The UAB campus and the technology park also generate small refurbs in shared flats and converted offices. AP-7/B-30 congestion pushes us to morning visits for local clients.
