The research consists of the set up of a game simulating a e Collaborative Working Environment - CWE - in Architectural Design. The use of a game is particularly useful as it makes it possible to simplify the complex terms of the problem and, through the game itself, makes it easier to study knowledge engineering tools, communication protocols and the areas of an ICT implementation of a general model of collaborative design. In the following several characteristics of the game are given (also with reference to other games) such as, participating actors (Wix 1997), the “pieces” (construction components) used, the modular space employed, the PDWs/SDW dialectics, the screenshot of the interface prototype, the score.
