Otto Riedl Tenement is a habitation building located at 2 Świętojańska Street, in Bydgoszcz, Poland.
The building stands on the western side of Gdańska street at the intersection with Świętojańska Street.It stands close to remarkable tenements in the same street:
The house was built in 1911–1912[1] for the baker (German: bäckermeister) Otto Riedel, according to a design by the architect Paul Sellner.
Paul Sellner has been a student of the architect Karl Bergner. In 1904, he opened his own architectural study office in Bromberg, where he stayed at least until 1922.[2] In Bydgoszcz Paul Sellner also designed, the building at Gdanska Street 95 in 1912–1913.
Otto Riedel moved to Świętojańska Street 2, then 48 Danzigerstrasse, in 1891[3] to establish his bakery. He had the house rebuilt in 1911–1912 and kept his business running in the new building.[4]
The edifice also housed a hardware store, German: Engelhardt Droguen since 1915.[4] Otto Riedel lived there until at least 1933. There is still today a hardware store ("Drogeria Aster") at this address.
Vincent Bigoński established here his bakery in 1924.[5] After his death, his son and now his grand-niece have been running the shop at Gdańska Street till 2020.[6]
The house reflects the architectural characteristic of years 1900–1910, as far as early Modern architecture is concerned.[2]
The building block is massive, in that way it balances the symmetry with the opposite building.
Both facades have a modest decoration but it is underlined by various components (pilasters, balconies).
