As part of the New Frankfurt-project Lihotzky created the Frankfurt Kitchen in 1926, which was the prototype of the built-in kitchen now prevalent in the Western world. Based on scientific research by U.S. management expert Frederick Winslow Taylor and her own research, Lihotzky used a railroad dining car kitchen as her model to design a "housewife's laboratory" using a minimum of space but offering a maximum of comfort and equipment. The kitchen measured just 1.9 x 3.4 meters. Kitchen surfaces were painted blue-green as scientists claimed the color repelled flies. The Frankfurt City Council eventually installed 10,000 of her mass-produced, prefabricated kitchens in newly-built working-class apartments.
