I cant believe how much hutches has shrunk this year, mine was second hand and is wider and longer than what you can get in the same style as this year.
I would have a look at second hand as well as new, I paid £40 for mine, its 5ft x 3ft and two tier. A bit of paint, a little repairs and its looking just as good as new. Free ads usually have some ads for hutches, and your local papers of course. If you can, self built it better as you can make them the size you want to. The only downside to second hand, they usually dont come apart so transporting a fully made up hutch can be a bit of an issue - unless you have a big van, or know a man who does.
