Josef Frank’s personal style went completely against the strict functionalist ideals of the 1930s. He used colours and patterns, included both high and low, and did unabashed borrowing from various cultures and eras. Josef Frank called this “Accidentism” or “The philosophy of fortunate coincidence.”
“we should shape our surroundings as if they had arisen by chance.”
Josef Frank advocated a personal decorating style. He expressed that there’s nothing wrong with mixing old and new, with combining different furniture styles, colours and patterns. Things that you like will automatically fuse to form a relaxing entity.
Josef Frank also thought that it shouldn't appear obvious that furnishings are well thought out. In his book, Accidentism from 1958, he wrote: “... we should shape our surroundings as if they had arisen by chance”.
