Tim Maybe if sort out your stuff before you get the dust started. All the diecast in one spot, sorted by how ever you want. same with the plastic kits. Then pack it away for the remodel. If you are starting with a clean room it will be better.
I like the idea of laying it out before you start.
Do you want shelves around the top? Do you want to make a desk out of the cheapest thing possible ( no wrong answer here) or do you want to go with base cabinets for a kitchen? We have all looked at very nice models built on a door. I guess you have to decide what the room is going to be for over the long haul. What others think doesn't matter make yourself happy and comfortable, you will build more.
