A genre composed of several different varieties of show revolving around remodeling or rebuilding homes, and/or the yards around them. The genre is so popular that a fair amount of the Discovery Channel can be found dedicated to it, and at least two cable networks (HGTV and DIY) specialize in it. It's also a staple of PBS in the United States.
Some are straightforward "Do It Yourself" guides and instruction. A few are akin to game shows. Others are simply off the wall, and of course a subversion or two have popped up. In all cases, the appeal revolves around a voyeuristic appreciation of the improvements, playing on the viewer's desire to have or make those improvements to his or her own home.

- This Old House: The earliest episodes resemble DIY, but it quickly turned into something of a "showcase" program that presented high-end renovations of expensive properties using resources out of the reach of most homeowners.

- Homewrecker - a subversion courtesy of MTV in which a teenager gets revenge on a friend by having his or her bedroom transformed into an unlivable space resembling the original prank pulled (for example, a prankster who shaved all the body hair off of a sleeping buddy getting his room turned into a pulsing, throbbing cave covered floor to ceiling in hair).
