We were at a Christmas part yesterday. The people live in a concerted steel clad shed. It's on of those with a tall main building with a gable roof and two lean-to sections. They lived in the left lean-to, with was fitted out like a main house and the main part and the right lean-to were one large room which housed all the toys, with plenty of room left.
I just found this picture on the net, it could be the actual building, before it was painted and converted. The location looks familiar.
