I have 5 piggies and they all live in this 7X2 + 5X2 grids cage ( 245cm X 70cm + 175cm X 70cm = 8ft X 2ft 4inch + 5 ft 9 inch (or something, I'm not too good with feet, sorry
).
Grids are purchased here in Finland and unfortunately we have only one brand of them... They are connected with cable ties. The base of the cage is not grid, but compost fence, which fits exactly to the grids but fence pieces are bigger and also more sturdy.
Bedding is woodshavings and then there are small rugs, which fit into washing machine, and towels. Underneath rugs there are some big towels and under them "plastic fabric" (I'm not sure what's the right word for it in English).
This cage is quite easy to maintain clean. I vacuum the rugs every day and also change small towels daily. I change woodshavings in "pee corners" daily and in the big box I clean the dirty places couple of times a week. It takes maybe 20 minutes per day. I need to change the rugs only once a months or less if I have found good places for the towels

The 7 tables under the cage are from Ikea (in Finland one piece costs 5 euros, so they are really cheap). The boxes under tables are self made. They are made of plywood and I ordered the pieces of the boxes from a timber shop near us. Though they were a bit expensive, around 150 euros, I think they make the cheap tables look quite classy (and also they store a lot of stuff), so I'm really pleased with them
