Adding facilities.

[vonbach]

I know in theory its possible to add faction only facilities in theory.
As far as I know you can only make  facilities that replicate facilities already in the game.
But if I replicated say for example a recreations common or an energy
bank and renamed it for a particular faction would producing the normal facility
make the effects stack?

There are 64 slots for facilities and some of them are empty. The effects are hardcoded, unfortunately. So empty facilities have very limited use.
