That looks similar to the size of layout I'm planning (once I get the loft cleared). Main board would be about 16" wide but widening at each end and possibly 30' long. Its good to see what can fit in to an area. Thanks for posting and keep us updated.
Cheers, the thought of doing that length of tumblehome is daunting, but so was soldering white metal and I'm happy doing that now. I'm sure I'll be able to get some tips to get me going.
