I'm curious what some of you out there have done in terms of a base for your undertree layouts. In prior years I laid track directly on the carpet, but am creating something a little more permanent this year. Mine will be roughly 5'x5' with 2 loops of track and will include a tunnel and space for Dept 56 buildings. I plan to have a plymood base on top of facelying 2x4s or maybe sidelying 2x3s. There will also be a fascia board around the perimeter to act as a lip. The whole thing will be built to disassemble into 2 easily storeable 2.5'x5' pieces.
Questions for those of you with annual, semi permanent, undertree layouts:
-How far off the ground is your track?
-Do you have the tree stand on top of any platform, or does it sit down.
-How far into the room does your layout extend? Do you have issues with room for gifts?
