The aim of this thesis is to try to interior design modern art house type Kunsthalle, in the former Neolog synagogue from the famous German architect. The interior design is so new links (inserted designed interior) and old (original cleaned area). After interviews with people involved in the reconstruction of the synagogue and careful examination of all available evidence, I tried to arrive at a design symbiosis of old and new. One important factor that affected the entire proposal was an effort by the decoupling of new construction and furniture to old structures, or if you are in the slightest degree. The proposal is also kind of answers and solutions to the realities of space, which this unusual property provides. This is mainly a multifunctional space. The proposal of several model variants of how the operation Kunsthalle and its parts could look like. I focused mainly on a proposal cafe, changing rooms and information center associated with the sale of tickets, permanent exhibition dedicated to the history of the synagogue, children's playroom and their own exhibition space. I tried to create a playful and unobtrusive interior, meeting and taking account of all aspects and factors of such an area of focus.
