A genre composed of several different varieties of show revolving around remodeling or rebuilding homes, and/or the yards around them.
Some are straightforward "do it yourself" guides and instruction. A few are akin to game shows
. Others are simply off the wall.
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.
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.
