The tenement at 91 Gdanska street is a historical habitation building located on Gdańska Street, in Bydgoszcz, Poland.
The building stands on the western side of Gdańska Street, between Świętojańska Street and Chocimska street.
It stands close to remarkable tenements in the same street:
The house was completed built in 1898[1] by the architect Fritz Weidner, a German builder who came to Bydgoszcz at the end of the 19th century, and had a frantic building activity in the city between 1896 and 1914.The architect lived in the tenement he built at 34 Gdańska in 1912.
In the same area, Fritz Weidner built houses at the following addresses:
The tenement at then 52 Danzigerstraße,[2] was first owned by a master stonecutter, Carl Bradtke who lived until 1898 in Dworcowa street[3] (German: Bahnofstrasse) before moving to his new house in 1899. He still kept his shop of"Marble commodities at 52 Bahnofstrasse until the start of World War I.[4]
Carl Bradtke also commissioned another local architect, Józef Święcicki, for the construction of a nearby tenement at 93.
The house presents forms of prussian Historicism, at a transition time from the Eclecticism to Secession movement.[5] The facade has gables with different forms, bay windows, loggias and various shaped windows.
The main frontage is flanked with triangular topped gables. The middle section play on symmetry, through the network of arcades and open loggias, while the upper part is purposefully designed asymmetrically.
This design is a choice undertaken by Fritz Weidner: to part from stuccoes for decorative arrangement as architectural elements.[6]
Interiors have noteworthy elements, especially the ceiling in hallway and entrance adorned with flower stuccoes.
The building shows similarity with a neighbouring one, at 79, also designed by Fritz Weidner.
