How about futuristic, armored blimp buildings?
There's tons of area on a gas giant, and you can spread out in 3D no problem.
The common house zeppelins could float to a level near 1 atmosphere pressure, factories would float up and down to the level where gathering their particular resource is easiest.

Gas giants are just so freaking huge that 8 billion Zeppelin houses would rarely ever meet.
You could avoid the stormy areas (go up/down/north/south) with basic propulsion, and being in a 500KM/H wind dosen't matter when you're moving at 500KM/H with the wind. Your airspeed is almost zero, and there's no ground to compare to or crash into.
