Quick sketch of Wayfarers' Haven
It's a toroidal structure encircling an asteroid.
The Torus is the main axis. There should be greebles on it as it's far from smooth. Remember, it's a refugee camp that turned into a city-state over time, so there's all sorts of ad hoc stuff bolted to the axis.
There's a breeze circulating around the main axis, allowing you to float around it like a lazy river.
