As a rescue I see lots of different hutches when I homecheck and also that people offer me when they don't want them any more.
I personally think that all Pets at Home hutches that are made this way are totally unfit for purpose. The quality is so poor that unless you stump up and buy a cover, you are bound to have water seeping in and making the ply mouldy during wetter weather. If the hutch was good enough quality, hutch covers just aren't necessary. The money spent on covers if invested in a better quality hutch from the outset, would mean a hutch made of Scandanavian pine could be a good value option. I am sure that many people are happy enough with their hutches from P@R, but this is my personal experience.
The hutches made in China (most of these kinds of hutches are made of Chinese Fir) are so light they are like balsa wood. The grain of the wood is so open because it's a fast grown timber that there is no strength and bunnies can chew through it really quickly. They are bought in huge container loads and shipped to the UK and sold for huge profits.
And usually the ply isn't actually plywood at all. Plywood is supposed to be lots of layers of laminations of wood that build up to make strong boards. The 'boards' in these hutches are actually two thin layers of thin timber with an air pocket inbetween. Not the same thing at all.
So not just from a space perspective (as I don't like double storey hutches much anyway) but from a quality perspective, I find these hutches (and those from other suppliers who use the same producers in China) are not worth having. They may work inside a shed or as a shelter in a house rabbit situation but I know so many people who have been hugely disappointed with these hutches. I had one here and it was supposed to have been used for a few months (I took the rabbits in 4 months after being bought with the hutch from Pets at Risk) and I ended up smashing it up as it was mouldy as anything because I didn't use a hutch cover.
There are so many good makers these days who use Scandanavian Fir, that is dense and will with the correct care, last for 10 years plus. Look at the grain - the timber takes years to grow and is incdredibly strong and very heavy when made up.
I have a selection of hutches here

Kernow Pet Housing
and I recently added a Boyles hutch to my accommodation as it came in with some rabbits - the quality is very good.
I also have 5 second hand Forsham Arks, which, whilst are not my favourite, they last a very long time with minimal care.
