It's a tv show about building your own home in the UK and Ireland. It shows the up and downs and difficulties involved in a self build. Reviews here on IMDB are pretentious to say the least. Over aliasing every aspect of it it's a diy show for mid week tv pre prime time. And just to say one last thing. 18 years it running. Season 18. So it's doing something right.
