the room I have to build a layout in has 3 doors that go to attic storage space. works great for the lionel & Mth Boxes laying around but doesn't work for giving me the whole room as a base for a layout. my question is this building a around the room layout has been out of the question because of the doors the trim height on top of the door is 48 inch's would that be too high for the main level of a layout ? that way the doors would still be able to open under the layout? If 48 inch table height is good then I can do a around the room type layout. I like big long trains seem to have more passenger trains than anything. right now I am doing a carpet layout. photos attached the last photo is of a proposed layout I played with this weekend when I had time daughters B-day and all. was thinking of having a ramp down to a lower level but have no idea how to do layers in scarm
