In our campaign, the Dwarven district on the asteroid, The Rock of Bral, was renovated with magic to have a 3-story tall Dwarven "mall" that has sub-levels. The Dwarves live in the sub-levels, and their shops are in the top above-ground levels.
I hand-drew the maps, and they are functional, but poor. If anyone wants to take the hand-drawn maps and make them nice, I'm putting the set at this site:

The already-nice maps of greater Bral are borrowed from another site. One square is 27.5 feet on the hand-drawn maps (to make them match the scale on the Dwarven District map with the scale shown from the published Rock of Bral map.)
* Circles on the maps represent spiral stairs, normally to all levels. But circles can also be tables (especially when in the courtyards), drawn way to large and not-to-scale.
* Squiggles within rooms represent stairs, too, but normally only to the next level.
*The hexagon is an existing Bral tower that was not allowed to be demolished since it was owned by the prince. The new structure just incorporated it.
At 27.5 ft / square, these rooms are larger than you think. The length of the entire complex is 1100 feet.
I can provide the shop descriptions and owner's race for each and every room, too, if you want them. Not all shops are Dwarven.
