Hi Mojarn,
personally, no, but the old wargaming club had four 4' x 4' tables fixed to the wall with hinges and folded flat to it when not in used. They were lowered down to rest their free end on trestles. They worked well, and a larger size could be managed. No permanent 3-D terrain features, though!
A nice design I've seen for a model railway track uses a chest of drawers of the sort which have drawers on sliding rails. The table replaced one of the drawers, and simply rolled out for use. A false drawer panel fixed to the end of the table camouflages it when not in use. This too needs support when extended. this could be limited by the depth of the chest of drawers, but a central hinge could permit the table to first roll out and then pivot open. If you get the whole chest of drawers, you may as well store your armies and rules and measuring stuff and dice and templates below. Useful!
Other designs (again from model railway catalogues - useful hobby, this!) are the classic board on castors sliding under a (solid) bed and the table suspended close to the roof on pulleys, lowered down for use - should be supported during use too, unless you get earthquakes in Finland, in which case it's better left suspended....
cheers.
) and decided that since you couldnt use 3d terrain built into it permanently, then it wasnt what I wanted. 'Course, I have since gone back to a flat, terrain-free table design anyway, so what do I know?
