Manhole cover up

Hi..
Im renovating and extending a bedroom to the rear of my existing house. My dilema now is there isca manhole inside the newly extended bedroom. My contractor say its safe to just create a seal openable chamber to cover it.
I hv limited budget now. My concern is will it be safe and will there be smell even if its double seal?
Havecthis been done pls advise.
Thanks for any advise.
