I'm thinking of creating a new layout with a semi modular design so it would be easier to disassemble and reassemble when we move. It would be some have 4 x 4 and 2 x 4 sections. Homosote as the top surface. It would not be attached but just sitting on the frame. I have an idea in mind how I want to do it, but the only part I'm not sure of is how to brace corners to keep it sturdy. On my current layout I screwed some 1 x 2 material from the legs to the top rails. I'm trying to figure out something that would be a little easier to take apart and put back together or even a better idea for the corner legs.
