An open book lies on a carpeted floor with its pages cut into rectangular frames, leaving only the borders intact and strips of paper scattered around.

DIY projects always start with optimism. A quick trip to the hardware store, a couple of online tutorials, and the bold belief that “it can’t be that hard.”

Unfortunately, these projects prove that ignoring warning signs like “hire a professional” or “this requires structural engineering” can lead to absolute chaos. From questionable carpentry to plumbing crimes, here are 17 DIY projects that boldly marched past every red flag and paid the price.
