This diploma thesis investigates the design of a new museum of Bauhaus in Dessau-Roßlau, Germany. In 2019 we celebrate the 100th anniversary of the foundation of the Bauhaus. To commemorate this anniversary an International Open 2 - phase realization competition held by Bauhaus Dessau Foundation (represented by Director/CEO Dr. Claudia Perren) and The City of Dessau-Roßlau (represented by Mayor Peter Kuras) was published in February 2015. This diploma thesis is a response to this competition and its outcome. Since 1996 is the main Bauhaus building jointly with the Masters' Houses a UNESCO World Heritage Site. Together with other buildings of this period, Dessau attracts approximately 100.000 to 120.000 guests from all over the world each year. The challenge is not only to present the scond largest Bauhaus collection (Bauhaus Dessau Foundation) but also to introduce the school itself. The proposed site is located in Stadtpark (city park) of the city Dessau-Roßlau and thanks its placement - halfway between all Bauhaus related sites - suggests a close connection between nature and the Bauhaus heritage of the city. Chosen building site is well connected locally and nationally - to the northwest within the site's immediate vicinity is the city's main railway station and the site is directly adjacent to a locally important street - Kavalierstraße. The construction should provide space as well as the technical conditions to facilitate a proper and professional presentation of the collection. The task for the new museum is to provice all national and international visitors and tourists, researchers or designers with the knowledge of the Bauhaus time, context, influence and legacy.
