SUSPENDED CEILING IN BASEMENT_ ADVICE REQUIRED

HELLO. I HAVE RECENTLY COMPLETED A BASEMENT AND ALL THAT'S LEFT TO DO IS THE CEILING. THE JOISTS ARE BARE. BUT THERE ARE ALOT OF PIPES AND CABLES THAT I WOULD LIKE TO KEEP EASY ACCESS TO. SO RATHER THAN A PLASTERBOARD AND SKIM CEILING I WOULD PREFER A SUSPENDED CEILING. THE MAIN ISSUE IS THE HEADROOM. CURRENTLY I HAVE APPROX 204CM FLOOR TO JOIST DISTANCE. DOES ANYONE HAVE ANY EXPERIENCE ABOUT THE MINIMUM CEILING VOIDS ALLOWED TO FIT A CEILING COMFORTABLY. IDEALLY I CAN AFFORD ABOUT 100MM VOID.

APPRECIATE ANY ADVICE AND EXPERIENCE ON SUCH MATTERS.

Thanks for the quick reply. Essentially it's a complicated building with a mixture of commercial and residential supplies. The sad part is that it's going to get more complicated. Hence going forward the future tradesmen will love me more if I install an accessible suspended ceiling and it is highly likely they will make comments such as " well planned , who ever done this".

Ideally need to get into the ceiling void and joist cavity. Future service and modification are inevitable.
Thanks.
