was the most important architect of the association of building smaller residences in Halle (Kleinwohnungsbau Halle AG) and was appointed its chairman three years after it was founded. After studying in Munich, Darmstadt and Karlsruhe, Fallen acquired the title of government architect in 1925. In the summer of 1926, Faller joined the architectural firm Bruno Föhre in Halle (Saale). One of his first projects for the Kleinwohnungsbau AG were the apartment houses in the middle part of Benkendorfer Straße. The architect had already built there for the cooperative federation of large families. Faller ensured a harmonious realisation of the two cooperatives’ projects next to one another. In 1926, he built rows of new houses for the estate on Stadtgutweg and in 1927, a block of 13 houses on Damaschkestraße. The beginnings of the Landrain opposite the Getraudenfriedhof were created under his direction in the 1930s. At this time, Faller also built the Reilshof. Almost all the flats and estates created by the Kleinwohnungsbau Halle AG into the 1930s were influenced by Faller, such as the Vogelweide estate with its 520 small apartments.
