The subject of the dissertation work was to manage the interior design of creative and educational center Prudentia in Ružomberok. I proposed this work as a pre- dissertation work in connection with our Ružomberok's synagogue already last semester. The principal idea of this project was to put together old and new architecture and to find their common utilization Since the synagogue was used as a place for education and gatherings of people in the past. Also current designated function of the new building was conceived in a similar way. That is why I chose, for its main use, a library which will be associate with a coffee bar and relaxation room for reading where people can spend their leisure time and educate yourself. In the interior I mainly pay attention to the parts that are accessible to public and visitors. First part is the coffee bar that is located at the first ground floor. After coffee bar, there is a book store and toilettes which serves for visitors. I tried to create pleasant and friendly interior where people would like to go come to relax, read books and gain new inspiration. I was using components from massive wood, for example floor, facing or furniture, during the designing process. Wood is one of the most beautiful materials that brings warmth and pleasant atmosphere. I matched monochrome colors with the wood and to vivid the interior I used ice blue, mint and shiny elements Barrysol. New building by its outside architecture is clear, simple and elegant. Moreover, it looks cold and so its interior should look warm and comfortable.
