For reference I spent £2.99 on wood glue and used some black gaffer tape and sticky back plastic that I already had around. I used a pair of scissors, chisel, hammer, file and tenon saw. The rest of it is quite literally rubbish. Or more accurately recycling. It's just that I'm temporarily detaining it here before it goes on to be recycled. All the decoration is chocolate bar wrappers. Even the foil on the pyramid came from chocolate bars.
This is the pyramid face, eventually it'll go all the way up.

Here is the Chocolate Pyramid in all it's glory!

Here's the best shot I could get of the wrap-around recycling symbol in two tone foil on the centre pyramid.

So there we are. Comments please?
