The designer of the villa, József Fischer (1901–1995), was a member of the Hungarian group of CIAM (International Congresses of Modern Architecture). His house at the Napraforgó Street experimental housing estate (1931) and the Hoffmann Villa on Szépvölgyi Road (1933–1934) are outstanding examples of Hungarian Modern architecture. For the Radó–Walter family, he designed a home set on pillars with a flat roof and roof terrace, elements that reflect the principles of Modern architecture formulated by Le Corbusier.

The structural engineer for the house was the first female Hungarian engineer, Eszter Pécsi (1898–1975), Fischer’s wife. Pécsi prepared the structural designs for numerous buildings in Budapest in the 1930s, including villas and condominiums designed by the members of the Hungarian group of CIAM, as well as the OTI apartment houses on II. János Pál pápa Square. She emigrated first to Vienna and from there to the United States of America in 1958. She had a prominent career as an engineer in America as well. In 1965, she won the “Best Structural Engineer of the Year” award for the method she developed for the foundations of high-rise buildings built on the banks of the Hudson River.
