I'm just concerned when the Rabbit Welfare said I should think about getting a new one. I paid £180 for mine and thought it was large enough because the hutch at the top is big and it's a 6x3 foot run at the bottom. I'm doing some upgrading today with new hay boxes and litter trays and loads of new toys. Due to the cost of the shed and not knowing if I'm moving in 6 months, I think I'm going to attach a new 6x3 run to the side for extra room. What do you think?
