Re: How to make a roof with clay tiles
Before you go into DIY mode, do check to see if a firewood 'Hüsli' requires a permit in your Gemeinde.
It does in ours - which we found out the hard way. Once that woodpile is turned into a neat, orderly stack with weather protection it becomes a building - and if over 60cm or 100cm (in our Gemeinde) it requires written permission from your neighbors. If neighbors refuse and one still wants to go ahead, a 'Kleinbau' permit from the Gemeinde is needed.
But as always in Switzerland, YMMV. Check your local regs.
Good luck with your project.
