Rheinwohnungsbau GmbH began serial renovation of 16 buildings in Düsseldorf-Urdenbach in June. By the end of 2026, 140 rental apartments on Corellistraße will be modernized. The company is using standardized procedures designed to save time and costs. According to the company, it is one of the largest serial renovations in Germany – a procedure that is still rarely used on a large scale in the housing industry.
