You could try to build a barbeque in the style of a ‘Dalek’.
If it was on castors, it would be easy to wheel around the patio and would also serve as a conversation starter.
You’d always have the tongs within easy reach.
The very top part could be used to defrost meat.
Below that, you’d have the grill.
Below that, in the base, you could store your barbeque coals.
(I’d design this so that your kids wouldn’t climb inside and get CO poisoning. And I’d use locking castors to stop it careening around at 300 degrees centigrade.
Now you can use your iPad to sketch out the preliminary blueprints:)
