Going potty!
Whilst on the subject of construction, how could I resist the humble Porta-Potty, or as we often refer to them here in the UK (Porta-Loos - a phrase our American friends find totally hilarious).
This version is decorative only but there will be a working version too. The only toilet without 'privacy' problems is (alas) the 2-tile stall toilet, but I can place two cabins together - the toilet in one, and the animated door on the other, and it should look convincing enough.
I could of course make a 1-tile version too, but it could have no animated door and Sims will demand privacy before using it. I might make one for kicks anyway - just to laugh ruthlessly at shy construction workers!
