If you were to google "Free Rabbit Hutch Plans" and look at the first few sites, there are some very good resources on those pages. You could also check with your local library to see if they have any books on building hutches. Good luck!
The library is an excellent source for hutch plans. (In rabbit books too). Also the club 4-H and Future Farmers of America have hutch plans. Many Hardware/Feed/Lumber stores carry plans.
You can look online for free plans. You can often find them there. You could also try and find pictures of hutches and figure out how you could build your own. If you don't like to build you can buy hutches that you can put together yourself.
