Housing is currently a big issue in Rotterdam. The heavily disputed policy document ‘Woonvisie Rotterdam 2030’ envisages the demolition of 15,000 cheap flats and the construction of 26,000 upmarket dwellings until 2030. Historically, the housing stock in Rotterdam was dominated by workers dwellings. After the war new residential areas were developed in the outskirts, while the city centre was reserved for business functions. Today only 5% of Rotterdamers live in the centre. Now a densification with residential highrises is underway. At the same time, there’s also space for small, creative infill projects, developed on private initiative. Outside the centre, many neighbourhoods consist largely of social rental houses, which constitute 58% of the total housing stock. Besides demolition, there are some softer approaches, such as the the unconventional kluswoningen concept.
