Krayl was one of the architects interested in the possibilities of the "glass architecture" advocated by the writer Paul Scheerbart. In 1920 Krayl began designing "suspended and swinging architecture," a feature of Scheerbart's 1914 novel "The Gray Cloth". Krayl designed a "Crystaline Star House" that hung from the side of a cliff. Krayl also wrote a series of articles that were published in Taut's journal "Frühlicht" ("Daybreak").
