This paper outlines a project suggesting a prototypical distributed-digital-design application system for integrating design process. Up until recently, the computing resources of an organization or project group were spread across many different systems in different spaces. This state of affairs is creating a growing interest in distributed-digital-design integration due to the needs of direct collaboration among location-independent project partners spread in the world. The aim of this research is to propose a new paradigm for a digital design system by combining research on integrated digital design applications including BIM(Building Information Modeling) with Web technologies such as Java and VRML(Virtual Reality Modeling Language).
