Change is a reliable constant. Constant change calls for strategies in managing everyday life and a high level of flexibility.
Architecture must also rise to this challenge. The architect Richard Buckminster Fuller claimed that "A room
should not be fixed, should not create a static mood, but should lend itself to change so that its occupants may play
upon it as they would upon a piano (Krausse 2001)." This liberal interpretation in architecture defines the ability of a
building to react to (ever-) changing requirements. The aim of the project is to investigate the flexibility of buildings
using evolutionary algorithms characterized by Darwin. As a working model for development, the evolutionary algorithm
consists of variation, selection and reproduction (VSR algorithm). The result of a VSR algorithm is adaptability
(Buskes 2008). If this working model is applied to architecture, it is possible to examine as to what extent the adaptability
of buildings – as an expression of a cultural achievement – is subject to evolutionary principles, and in which
area the model seems unsuitable for the 'open buildings' criteria. (N. John Habraken). It illustrates the significance of
variation, selection and replication in architecture and how evolutionary principles can be transferred to the issues of
flexible buildings. What are the consequences for the building if it were to be designed and built with the help of evolutionary
principles? How can we react to the growing demand for flexibilization of buildings by using evolutionary
