Hi All, my wife and I enjoy doing these videos so our GrandKids get to see our set up. It is on an 8' x 8' platform that is made of two sheets of plywood so when we have a "bounce back" kid we can disassemble it and turn it back into a bedroom. The Lego buildings allow us to change the layouts easily for different seasons or holidays. There are more videos on our YouTube channel. Enjoy, have fun.
Regards,
Eddie & Pat Z
