As Wiki says, steampunk is a style that originated in the 1980s and early 1990s and incorporates elements from science fiction, fantasy, alternative history, horror, and speculative fiction. It is an environment where steam power is widespread – be it in an alternate story like Britain in the Victorian Age or the “Wild West” – or in a post-apocalyptic era – that contains elements of either science fiction or fantasy . This style is rather unusual and is rarely used indoors. However, when designers use it, the result is so dramatic and impressive that you can’t think of anything. You just stand there and watch! The most popular space for such style experiments is a study or home office, as science and science fiction would be appropriate here.
