falling down air raid shelter, ideas

[fishpond]

Not sure where to put this, so:-
In my garden, as can be seen, it is dangerous, measures approx 12 feet by 8 feet, not sure if the floor is brick or compacted earth, I would like to have it demolished to make way for something else BUT WHAT?
Inside the shelter is lower than the surrounding ground by approx 3 foot.
There are brick steps going into it from the left hand side by the fence.
Any questions / ideas??????
Thought of demolishing everything above ground, having it rebuilt and using as a shed/fruit store.
I need ideas please

Has to be a Walipini I've always fancied one myself!

Loads of info on goggle - here's a starter https://www.treehugger.com/green-arc...ear-round.html

Love it, even though I have never heard of or seen one before.

That Wallpini thing looks a great idea, something else I might have a go at, I have all the double glazed windows from the side of an old conservatory that would make the roof.

The Walipini looks great.

Alternatively you could remove the dangerous bit above ground, drill drainage holes through the base (if there isn't any there for drainage) and use it as a massive, solid planter for invasive suckering plants like Pawpaws and Edible Bamboo

That Walipini idea looks good, or what about turning it into a pond!!

If you're only looking for growing related ideas, i reckon the Walipini is worth a go... what a great idea!

The other obvious alternative is to rebuild it as a bomb shelter for when Trump gets bored and starts firing nukes... for fun!
