Recently, i've wanted to build an Overhang beside my houses, and other similar structures, like a Ramada to meet under for a common area. While they can already exist, you have to build walls to complete a structure, and then remove some of the walls and hope the roof doesn't collapse. If done well, it becomes an Outdoor roofed area, like the ones shown above.
IDEA
Why couldn't we add a "Forced Ceiling Zone" that displays blue, and couples with the orange display color of the "No Roof Zone", displaying both zones when either is selected. It forces a roof to be built, despite a full structure not being built, but requiring 2 or more built walls for support. We could also use this to make Roofed paths with rows of columns, so snow clearing on common paths wont be required.
IMPLEMENTATION
Basically, it could scan the area for walls when you attempt to place it, and if it cant find wall to support a ceiling, it wont place the zone (like growing areas wont place on stone floors, but tracks proximity to walls instead of floors). This allows overhangs, and escape from rain and lighting (particularly early game, when no full structures are truly built yet) without building a full on structure with or without a door.
