Roger that. It seemed most of the buildings in Mos Eisley (the city we see most) were rarely (never?) square...they seemed mostly to be at least rounded off at the corners, if not entirely rounded. I think they were also most half underground for insulation purposes. Is that what your stairs are for?

Of course, I'm sure the Empire would just smack down some pre-fab outpost shacks or build big squarish Coruscant-style government buildings smack in the middle of things when they start muscling in...typical!
