I can see why people try to do things differently and I guess that plastic housing is something that tries to address certain issues, but I have to say that there's a reason why wooden housing has been the same kind of style for so long (even if it nearly all used to be too small), and that for me is because it works very well.
I feel that wood is more natural for rabbits, and I know that we humanise them somewhat, in particular by laying lino, adding litter trays etc, but I think that is a good compromise.
I also believe that repairing wooden housing is going to be much easier, especially from chewing, digging etc, whereas this would not - can't see how you could patch it up if needed. Going by how my monsters dig in the corners of litter trays making the plastic surfaces rough, I can see potential for damage that couldn't be fixed.
Apart from how the rabbits would use the space, I do also think it is incredibly ugly. But then so are some wooden hutches. Difference is that you can pretty up wooden houses but can't see how you'd do it with this.
I wonder how many people in the UK have one and what they actually think.
