Made this for my 3 year old son out of about 12 pallets of varying sizes. Grandma had a rusted old slide so recycled that too. May paint it soon but in two minds. I filled the gaps in the planks only on this side to pretty it up but the other hidden sides are gappy to allow climbing.
I took way too long to make it, about 3 days because I was on my own and had massively over engineered it with big ass coach bolts but it was a fun process and very satisfying.
