On the occasion of the first major Bauhaus exhibition in Weimar in 1923, an experimental house was built in the street Am Horn in just four months, which went down in architectural history as "Haus Am Horn".

The model house designed by Georg Muche was regarded as the prototype of New Living. Here, the revolutionary ideas of the Bauhaus were materialized for the first time in a specially designed architecture: all rooms are small, functional and arranged around a central living room with a skylight. The house had one of the first fitted kitchens, central heating, gas flow heaters, tilting windows and built-in cupboards.

The most important art school of the 20th century, the Bauhaus, which was founded with the appointment of Walter Gropius as director on April 1, 1919, created its only architectural testimony in the city of Goethe with this building.

The Haus Am Horn is part of the UNESCO World Heritage Site "The Bauhaus and its sites in Dessau and Weimar", which had a decisive influence on the architecture of the 20th century.
