With six children you start to get creative on using available space. I built this 3 bed bunk and loft bed with desk for my 4 boys. The desk is large enough for all their video games and xbox console. There is plenty of storage within the six drawers and a cubby behind the drawers with a secret door.
This is made from Douglas fir and is actually stained, not painted with a deep navy blue. It comes apart in sections, so it can be "easily" moved.
