Only a small percentage of the new homes built in the Netherlands in the last decades have been built by private commissioning (11.2 % in 2012, www.statline.cbs.nl).

This has consequences for the professional role of Dutch architects and the way they react to the changing role of their clients. The design methodology and attitude of the architect in the design ...
