I have a Poppy Den, we bought it for my friend's rabbit to stay in as he comes to visit every summer.
Don't think I have any photos with him in it though, as he spends as much time as possible out of it - we keep it on the patio, so we just open the door and put a barrier across our steps to the rest of the garden and he is free range as long as someone is out there.
Not sure I would keep a bunny in it for long periods of time as Frankie is quite a big boy and does look a bit grumpy if in it for too long. Also the divider thing is useless for rabbits as the hole is TINY, we took it out as otherwise Frankie would have got stuck!
I had the original guinea pig den 5 years ago and it is still going strong, but the build quality has really gone downhill so my newer Poppy Den definitely doesn't look as good!
The Dandelion one is definitely better quality but I don't think it's as big in terms of height and I wouldn't want bunny not to be able to 'stand up' properly.
Have you had a look online? Or your local garden centre may have some good hutches - one of mine came from there and it is brilliant, so easy to put together and really sturdy.
