Need to come up with a better battery storage solution

A year into this hobby i realised i needed a better way to store my lipos so i bought a good size metal tool box and lined it with 6mm fibro cement.
I felt confident this method would contain any flames in the event of a fire. (Not the gas or smoke)
So confident that kept it in the man cave sitting on a metal storage shelf.

Now 3 years later the man cave is littered with foam planes and unfinished projects and lots of other flammable material
and tonight i was checking the storage charge of all my lipos and was surprised to notice i have accumulated in excess of over 70 lipo batteries some beat up some a bit puffy and I'm starting to think it's time to come up with a safer storage method.

I live in Queensland Australia and with the Hot climate storing them in the garden shed isn't an option.
I know Hai-lee swears by storing them in the fridge but Putting 70+ lipos in the family fridge isn't an option for me ( Wife won't go for that ).
The Garage is used by the wife ( Hey she lets me have a man cave / Plane workshop so fair enough )
I don't know if an ammo case would stop a fire with 70+ lipos with multiple cells.
I think its time to some how move them out of the house .
I was thinking of a big fire proof safe from Bunnings and putting it out on the concrete pattio and heavily insulate it.
Dunno.
Any other flyers here come up with a solution for safe storage ?

Cheap second hand fridge, put in the man cave, fill with lipo and beer, jobs a good un!
Put the packs in batches in lipo bags or clay flue pipe lengths to separate them.
Also do yourself a favour and discharge and dispose of all puffy, tired or damaged packs. This will make storage much safer and make space.

Heck you can take some concrete blocks with steel cover with holes in it or space the blocks a tad just so no pressure can build up, no reason to spend a ton of money
