One of the key characteristics of urban-architectural workshops as a soft planning method is above all the fact that the authors are free of burden of formal facts and reference levels of the local environment, which do not influence the concept and the working process. Within this framework, the workshop presents an opportunity for the creator to focus primarily on the core of the problem, and work creatively towards a substantiated professional solution. In addition to the basic reference levels (programme, client’s needs, characteristics of space etc.) certain other circumstances such as ownership, economic, technical, local political and spatial development limitations can have a significant influence on the planning process and final project realisation. Their conscious exclusion from the set of reference levels can lead to formation of solely theoretical models, which are not generally acceptable and which, as a consequence, cannot be practically implemented.
