Often I just make the bottom half of a building and then 'run with it' and try to resolve the roof. Since I made the side wall areas of this building on the second story seven wide instead of five, there was a height difference to make up for if the stairsteps were going to meet up evenly and not have gaps.
My husband came and looked at the screen halfway through (I was complaining it was being a pain, and I should have screnshot it then) and said something like h*** No and went back to his own project.
and for a kicker - here is the interior (undecorated) version of the house, as well. It has two rooms on the main floor and one upstairs room.
The back room is perfect for a kitchen area, and has another door out, as well. Upstairs there are room for a double bed or two or three singles, and chests. This room also leads down into the mineshaft below the town.
Location : near Milliken in the Zayama Railway World, which doesn't have a story, I'm just sort of doing it for the joy of mapping and building.
