The Theonia Reichhardt house is a tenement in downtown Bydgoszcz, at 36 Gdańska Street.

[2] The Reichhardt family lived there since 1880[2] and the widow had the original 1875 residential building reconstructed as we can see now in the late 1890s.

The tenement was designed by the architect Józef Święcicki, who also designed (among others): For this edifice, Joseph Święcicki prepared plans for a building with large dimensions and a rich decoration, which was to span along the whole façade.

However, due to limited financial resources, the initial project was modified and eventually only the left side of the building got its luxurious ornamentation.

The building has an asymmetrical façade and eclectic wooden decoration of neo-Baroque forms.
