Subject of this thesis is to design interior of contemporary art gallery in a former heating plant building at Čulenova street in Bratislava. The work builds on the pre-diploma project, which focused on the overall processing of the object itself from an architectural and operational perspective. It aims to deal with the selected areas (lobby, café and shop), and their integration into a seemingly hostile environment in which they find themselves. An important step was to deal with the existing building structures and their use to their advantage (Column Hall). The essence of the thesis was to retain the industrial character of the object with the use of typical materials such as concrete, steel and glass, but in particular to add to his attractiveness utilizing current trends and technologies.
