This master thesis deals with the redesign of a mountain station in the Vitosha Nature Park in Bulgaria. The architectural design presents the creation of a visitor center, a restaurant and a viewing platform at the upper station of the "Knyazhevo-Kopitoto" gondola, which connects Sofia with the mountains. The first section of the thesis analyzes the location of the station from an urban perspective and with regard to the Vitosha Mountain. The analysis provides an overview of the nature park, its tourism and the mountain station relevance in the overall context of the mountain. The second part deals with the concept development, focusing on the shape finding, the program and the building circulation. The resulting design represents the implementation of the following conceptual ideas: the natural landscape continuation, the embedding of the mountain station into the existing environment and the creation of a panoramic view, by considering the functional, aesthetic and constructive requirements. Finally, the work provides a deeper insight into the structure, the constructive details as well as the exterior and interior effects of the building.
