||Advanced Information Technology today gives us the opportunity to implement sophisticated distributed systems for collaborative design. Persons with different interests and competencies in the building process such as architects, installation engineers, structural engineers, clients, builders can all at least theoretically be brought together in a distributed design space where a virtual building will be designed, build, and functionally evaluated. A design space build in a virtual reality environment will enable us to realistically and efficiently simulate the form, function, and construction of the building object under consideration.In this connection we made the following definition of a Virtual Workspace. 'The Virtual Workspace, VW, is actually the new design room designed to fit new and existing design routines. VW may well be a mixed reality environment. The VW will host all design partners from project start with different access and visibility (for persons and groups) in space and time to the project, and will promote building up shared values in projects. The VW thus acts as a communication space with project information support in adapted appearances. VW gives access to general and specific IT-tools 'The paper presents experiences from the early phases of user requirements formulations and design of such collaborative design spaces. The findings are mainly based on collaborative university and consultant engineering company work done in the EU project 'Distributed Virtual Workspace for enhancing Communication within the Construction Industry - DIVERCITY' as well as experiences from student collaboration in distributed learning environments and earlier research within the area.It is extremely important to bridge the gap between the user requirements specifications and the actual interface design and implementation of the underlying operational models of the distributed virtual workspace system. This is certainly true as we actually design a new type of design artefact that will highly influence the traditional working methods and integration of design resources. The early conceptual design of the virtual workspace follows the so called Contextual Design methodology which gives input to the subsequent data modelling work and implementation in an object oriented web distributed environment. The method used is described and examples on resulting Work Models (work flow, sequence and artefact models) are presented and commented on.
