The Italian sculptor Emilio Sala was responsible for both the internal and external sculptural decorations, such as mermaids, dolphins, and frogs on the roof of the building, sinking ships and hunting trophies on the exterior walls, and exuberant interior decorations, such as grand stairways and chandeliers depicting huge catfish strangled in the stems of lotus flowers. The exterior sculptures created by Sala were made out of cement. Production of the cement was by the «For» company of which Horodecki was the co-director. Cement was used exclusively as the primary building material by the request of the company's head director, Richter. At the time of the building's construction, cement was not popular as a building material, so its use was employed as publicity for both the house and the building material.
