Kas Oosterhuis and the artist Ilona Lénard, founded "Kas Oosterhuis Architekten" in Rotterdam in 1988. Today they are known by the name oosterhuis.nl. For Oosterhuis, the complexity of form and volume is associated with the complexity of data taken into consideration and meanings developed. In so doing, they have always regarded the computer as a basic tool, and they were among the first to use computers in their practice. This approach has almost always culminated in producing forms with sculptural outer qualities of a relative simplicity, contrasting with interior movement and complexity. By being convinced of the importance of the future role of computers in architecture, their activities subsequently led them to introduce onto the Internet workshops which enabled several Internet users to collaborate in the construction of one and the same form. It is this logic which underpins their current project involving eight houses at Zoetermeer, called Variomatic Housing. Future users will have a chance to vary the height, depth and width of the house by choosing images on the website. The situation in the landscape and the form can be altered; the effects of this on the costs are immediately apparent. The project has been taken up by the IFD Programme (individual, flexible and dismantable building), because of the innovativeness it introduces into client communications and because of the variety of the forms it makes possible.
