Past designs have been recognised as a significant source of knowledge in architectural design. IT offers the opportunity to represent these designs not only by text, graphics and images, but also by 3D-models, computer animation, sound and video. In spite of the growing availability of multimedia archives, libraries and case bases, their contribution to the development of students design craftsmanship so far seems to be limited. If IT wants to make a valuable contribution to this development, the challenge is not to passively provide students with information on past designs, but to (inter)actively support the dynamic interplay between these designs and the student's design process. We are developing a tool that fundamentally attempts to explore this potential by using information as a vehicle to initiate, nurture and improve this interplay. The tool, which is intended to assist (student-)architects during the early conceptual stage of design, is conceived as a an (inter)active workhouse rather than a passive warehouse: it is interactively developed by and actively develops its users? knowledge. We have implemented a working prototype of the tool, at first stage for the design studio, yet with the potential of expansion into the office setting.
