Why not reduce costs and use the local granite boulders as walls? Frankly I think that the builders were onto a good thing when they built these masterpieces at the Melville Caves in Victoria, less concrete, less bricks and a reduced area to paint. What a winner. Though I pity the poor plumber who had to find a granite free spot for the septic tank.

I really liked your first relief station, I respect those who don’t waste good used roofing metal. Don’t think I could dig deep down there around the caves.
