Thank you. In a little while, I'll set it in place on the layout to see how it "feels".

Well, the climate in Houston has some drastic humidity changes through the year, and temps range from 30 F in the winter to 100 F in the summer, but the layout is in a climate controlled room. On the old layout, which was in a non-climate controlled garage, a couple of the GERN structures where built similar to this with no problems. The plywood I used was an old piece of 3/4" "furniture" grade plywood, and that stuff gets used in all sorts of home furnishings like laminated cabinets and such.
The plywood core is "laminated" with plastic on the top and three sides. Only the bottom and back are exposed. I could put a sealer on those surfaces, but I don't expect any issues.
