I painted the background myself on a large piece of leftover formica from a demolished kitchen remodel. Acrylic paints and regular house paint cover most of the background. It took a lot of tries and placing random Playmo buildings here and there to figure out what kind of layout my painting needed. Didn't want to do all that work and find out that part of the background is going to be mostly covered by buildings anyway.The floor is a self adhesive cupboard liner from Home Depot (hardware store).
