Yes, I agree with robkelk.
The usable internal volume of a converted asteroid depends on how much rock was mined away. If Prometheus Forge is more a system of tunnels and caves at the moment, the usable volume can be as small as you want it to be... but they will still have lots of space to expand into later.
