Oh I am sorry I forgot where I found it, but I remember I just typed in Rabbit Hutches and found it that way, so you should beable to find it hopefully, it is expensive though, if you have a handy Dad who could build it and maybe it not so flash materials, it would be a lot cheaper, I found this one also, the only problem I have with these are they would be hard to shift around for their grass, my hutch was not flash but it had indoor/outdoor flow and was on castor wheels,.so it was easier to shift around for new grass and shade purposes.

This one is from the UK, maybe the one you like might have been also, not sure, I posted them for hoping it would give some ideas, perhaps for building them as well, silly me forgot to post where you could get them, so sorry.
