Something I always wanted to do was to run a challenge where we all ended up building the same house but decorating it as we wished (a bit like we did with Xander's house). I was thinking of building one room at a time, ending up with a house.
We start off with an empty lot and we buld rooms and decorate until finished. Pics of the rooms at each stage.
I could make a floor plan grid for each room and then we can add to it piece by piece.
I love these - I've run two of them previously at Spg. What we did was actually just describe the room and how it connected up, and then let everyone interpret how it went themselves. I don't think we got a single house that looked the same! I'd just adore to do one of these without having to run it! I'm in!
