In 1924, Guyer became one of the first women in Switzerland to establish her own architectural practice, opening an office in Zurich. Her projects often also covered interiors on which she collaborated with designers. One of her early commissions was a housing project with apartments for single women. In 1927, she was head architect for the first SAAFA fair exhibiting the accomplishments of women. She completed one of the buildings in only three months using prefabricated elements made of wood. When the fair opened the following year in Bern, her reputation was firmly established. Despite years of war and economic hardship, Guyer continued to run her business under her own name, experiencing an upturn in the 1950s.[1][2]
Lux Guyer married Hans Studer in 1930 and had a son, Urs, in 1933. She preferred to do her design work at night; in the early morning she worked in the garden and spent her days on building sites, at meetings or in the office. At weekends, she received visitors.[1]
Her architectural office was later taken over by her niece, Beate Schnitter.[3]
