I thought I would post this up even though it is not quite finished, to see what you think.
It is for at the edge of the board.

It is about 2' long and 5" high. The idea is that it can be used as an objective or just to block an edge of the board. It is going to be double sided. Out side and inside of a factory.
Inside wall not finished painting yet

On the front I have left a flat area where I am going to build a removable outbuilding or entrance way.
In the middle is a door to a cellar.

A small door at the other end. Still to finish painting.

The rectangle above the door is a magnet so I can fit inter-changable signs.

and one more of the whole thing.

I have used my normal building method with this. It is all made out of pizza trays mounted on MDF.

I already have ideas to make it a Factory with different signs for different types. My brother says it looks like a prison so I will make signs for that.
The out building can also be a chimney. I am also thinking of having different types of fences or wall which would make it look different again.
I am also thinking that in the future I will make two end walls and another long wall so that I have the whole factory.
Anybody got any other ideas.
