The investor of the villa was Ing. Dr. František Müller (1890–1951), co-owner of Podnikatelství staveb - one of the largest construction companies in Czechoslovakia, specializing primarily in civil engineering construction. The company was founded in Pilsen in 1890 by civil engineers Antonín Müller (1852–1927) and Vojtěch Kapsa (1855–1915) as a design office under the name "Úred. aut. stav. inženýří Müller & Kapsa, podnikatelí staveb v Plzeň". In 1904, its Prague branch was founded, followed by a company in Bratislava in 1921. After the death of the company's co-founder Vojtěch Kapsa, his son Lumír Kapsa took over the share in 1915. In 1921, Antonín's son František Müller also joined the company, and in 1923 he married Milada Krátká (1900–1969), with whom he had a daughter, Eva (1926–2004). The family lived in Pilsen until 1926, as did many of Loos' clients.
