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.
