This paper develops an innovative structure of knowledge collaboration forms that allows effective and creative collaboration among the actors along territorial design process. To contribute to the development of the social dimension of the sustainable development, we investigate a new methodology and computational tools for understanding and facilitating multi-disciplinary, cross-cultural collaboration in sustainable architectural-, urban- land- and ambient-scape design, through evaluating collaboration among project developers, local authorities, architects, engineers, contractors, building inspectors, clients and future users. Therefore, this proposed integrative tool increases the pool of knowledge and skills available to undertake activities that exceed the capacities of any single person or organization on its own, thus making possible the design and construction of complex skills, especially buildings and ambiences in urban or suburban environment
