Co-operation partner: Housing Department, City of Dortmund


According to the debt report of 2006, the past ten years have been characterised by a continuously growing number of sales in execution due to illiquidity of private and commercial real estate owners. At the beginning of the 1990s little more than 30,000 sales in execution were recorded in Germany while the number grew on average by 44 percent until 2001 (Höbel; Kloth; Behrendt 2004: 12). In the subsequent three years, the increase reached 90000 auctions, affecting Eastern Germany above average.The City of Dortmund followed this trend. It had approx. 500 auctions in 2004 (Stadt Dortmund 2005: 53). This is a about 83 auctions per 100,000 inhabitants – just below the average in North-Rhine-Westphalia. The location of sales in execution can be identified as spatial phenomena but their impacts have not yet been specifically researched. This project analyses the consequences on the urban space and the necessity of intervention.
