Yep, feel free to stick a wall up there, neighbour. I can't promise my inhabitants won't tunnel under it, though: they're not so much 'shady' as 'borderline insane'...

Also, you might want to know that I'm developing section 32 in the direction of way-over-the-top mechanical and industrial contraptions, so you might get some smoke and fumes blowing over that pretty wall of yours
