Bit of a last minute thing, but I've been researching making a fallout shelter in time for next week.
I found this www.popularmechanics.com/adventure/outdoors/tips/a6662/how-to-turn-your-living-room-into-a-fallout-shelter/ but it seems a bit basic.
I thought a better solution may be in blocks and concrete, but things like should it be concrete blocks or thermalite and what code lead to use crop up.
The other option of a garden chair and bottle of red wine, (certainly not Vodka) may be more suitable, and sod the DIY?
