The intention of this research is to develop a design system for geometrically complex Pasove houses. Research focuses especially on the link-up of the CAAD (Computer-aided architectural design) and the CAM process (Computer-aided manufacturing) and deals only with timber structures. The aim of the project is to develop a system that would automate a creation of the computer model of the geometrically complex timber structures and link it to fabrication process. It should be possible to use the system for houses of the size of a family house up to an apartment house. The advantages of the system ought to be the fabrication preciseness, economical availability, high speed of construction, eco-friendliness and above all absence of geometrical constraints.
