10. The Village Well and Lantern Path
Can I just say, a well is underrated? I built one right in the center of the village, with stone bricks and a little wooden roof, and suddenly every path in the village had somewhere to lead to.
Then I lined those paths with lanterns, one every few blocks, so the whole village glows at night. It is simple, it is cheap to build, and it makes the difference between a bunch of houses and a place that actually feels like home.
