The part of the Danish housing stock built after World War 2 being apartments in multi-storey buildings accounts for around 20% of the total stock of dwellings. In general this part of the building stock is of a reasonable standard of to day both functional and technical, as major renovation and repair have been executed over the last decades. Future problems are therefore of a nature described as projecting (heavy) trends of to day: a much wider demand for apartments being very different by size, by lay out and by possibility for individual equipment – of cause in respect of a future with over all demands to sustainability and also a quite different composition of the labour market.
