Sunday 9 - 17...

Mine is in a 12 x 32 room I built attached to the backside of my barn. It's no longer holding up too well after 20 years; barn was built with second-hand lumber and wall is warping on me. I am going to build a new freestanding building (25 x 40 planned) next spring. Current partial layout was built with disassembly in mind.
 
I got lucky. When we were having our house built we got the builder to move a couple of doorways different from their standard model and I wound up with one 12' x 12' bedroom that is accessible only from my den. Nothing in it but my layout and a workbench.
 
Hah!..Lots of you have houses over your layouts....Mines in the attic.
I have heat and Air Conditioning. Heat in the summer...AC in the winter......
Should of modeled a desert area, instead of the Northeast. That way the tempature up there would match the scenery.
 
My previous layout back in New Orleans was 12x12 around the walls with a peninsula. Now it's a 3x6 Scenic ridge layout in my 10x10 office here in the house we're leasing in Houston.

We'll be shopping for a house in December to buy in Jan/Feb and you bit I'll be keeping an out for "train room" to use. :)

I really would like to do HO scale for my next layout, so if I can't get a decent sized in-house room, the garage will be my next train room.
 
Right now, it along with a very few other things, in my mind:D , but will eventually build in a building, I have yet to get, in the back yard. Still gotta do surgery and rehab 1st:cry: , but will eventually get it done:thumb:
 
It looks like the majority of the Gauge members are building their layouts in the basement.
That's exactly where my layout is, too.

(Funny: Everybody here in Europe believes that Americans NEVER have basements below their houses!!! :D:D:D Now here's the prove that the contrary is true! :oops::rolleyes::p)
