English: Architectural plan by August Berger (1860–1947) of the 1st floor of "Sonnenhaus", erected in 1914 for the merchant, entrepreneur, art collector and patron of the arts Otto Bamberger (1885–1933) of Lichtenfels, Upper Franconia, Bavaria, Germany. – Explanation incl. a translation of the plan's descriptions: The Villa's 1st floor or ground-floor isn't at the same level as the street. It is a so called Hochparterre. This German term with partially French roots describes an elevated position above the ground which could be reached via seven steps. The main entrance of the Villa is located in the lower left of this plan. It's square clearance was created as a windscreen. The hall (= Diele) houses the staircase which leads to the basement as well as to the upper floors. The kitchen (= Küche) is the large room in the upper left of the plan. On its outside is the veranda, which could been served by the cook through a window. The family had breakfast there. The cook called Kunni (nickname, abbreviation of her correct first name: probably Kunigunde) was supervising the household. She lived in a room of the Villa. The maid Gretel also had a room in the Villa. Her job was the housecleaning. The kitchen's pantry (= Speise[kammer]) is in the upper left of this plan. The living room (= Salon) is in the lower part of the plan and through the hall could be reached easily by visitor's of the Villa. Through wide sliding doors with glass windows the living room was connected to the spacious dining room of the Villa. It provided another door to the conservatory (= Wintergarten) which had a side entrance to the spacious garden. – The dining room of the villa, which was located between salon and conservatory, was redesigned into a salon from about 1927, while the original salon at the same time was furnished as a library. In addition to many high-quality books on art and architecture it housed those parts of Otto Bamberger's extensive art collection of Expressionism which were not exhibited in the rooms of the Villa. As a result of this conversion and re-design, a window to the staircase of the villa's main entrance had to be concealed before the large shelf cabinet of the library was positioned at this wall. The entire furniture of the house incl. kitchen was executed by the famous Bauhaus, mainly by the furniture designer Erich Dieckmann (1896-1944), partly together with Karl Keller (1903-1979).
