In a beautiful downtown loft, I built two white bunk beds, assembled side to side along the back wall of the bedroom. Four sisters happily share the room.
The guard rails are higher than the normal and the footboards are totally closed to provide a bit more privacy to each child. The ladders don’t reach the floor so a trundle bed can be pulled out from underneath.
Every bed has it’s own wall mounted light with its own easy-to-reach switch. The ladders have additional cut outs for the kids to hold themselves safely as they go up and down.
