The design theme is to create a subterranean cultural compound including hybrid programmes under the general theme [Vyšehrad Spring] on the historical site in the north of Prague. The goal of the project is to add a secondary identity to the site, a place which will be characterized not only by its historical value from the past but also its creativity to the future. The definition of selected programs includes a theatre, performing art centre, library, gallery, artisan studios and a sanctuary (meditation centre), encouraging creativity from multidimensional knowledge and responding to local culture and tradition. After the midterm, the design scope has been narrowed down to one single building, a Performing Art Centre, which is the most complex and collective programme from the masterplan. This building includes a professional multi-form theatre for performing arts, a learning centre for young professionals and amateurs, and public access areas for various collective activities. An phenomenological approach has been applied during the process of designing the architectural language. The inspiration source for architectural language are the indigenous images and city experience of Prague, including contiguous colonnade, traditional crossing house typology, color & materialism of the old town, and its unique townscape in the castle district.
