Palletable alternative design.

We only had the local style bricks - much larger than UK clay bricks but with a series of square holes through them.

Instead of building a double skinned cavity wall I decided to try a single skin but fill the holes in the bricks with sand. That would get rid of our piles of surplus bricks and sand and if we built the structures on pallets we'd put those to good use too. Nik set about painting the pallets to give them a longer life.
