thats not bad when one can pull out the bottom to clean it more easy,

we put a large flat plastic tray inside one of our large cage, then you only need to get out the toys and huts and Ffood bowls to take out the bottom and throw away the straw or pellets, maybe have a look at this...
long time we used a real large old wooden dog house that my father build new for the rabbit, maybe this could be an idea, you could use the front opening to let the rabbit out in there run and the top you turn to be the front and you put mostly away (let a small part be as low wall for rabbit and straw staying inside(10cm high) when opening the door) and build a wire door to swing open to one side or both sides, or when you work well you can even swing it so that it is on the top... not easy to tell howthe look was, but it was great, large place, they could jump and run around you could put in a large hut for tthem to sit on or wall walk for extra place to sit..
i once even did think for fun^^ about something like this (maybe with wire close top or Windows(to Keep danger out too) they cant fall down or put head through and maybe a sort of not sliding slide over the stairs and arround it a rabbit run, and tiny door to close them in over night when needed)....cut be funny to try^^ :
