First tenders for the design of a new building were put out in 1862. However, due to a lack of financial resources the plans were not realized. After the Society was given land by the municipality, another competition was announced in 1894, won by the Warsaw architect, Stefan Szyller. He presented an architectural design in neo-Renaissance style with classical elements. The portal is ornamented with allegorical figures and sculptural works by Zygmunt Otto. The architrave of the building is engraved with the Latin word "Artibus".
