I'm still working on the perfect henhouse design - now up to Mk 22!  Now tending towards plastic sheet sides with external creosoted framing and Onduline roofing for ventilation.  Don't use recycled board - the structure breaks down much more rapidly than the price justifies.

You mean the recycled plastic sheets break down? I was just about to buy some from Mole Valley.

Yes, an Animal Arks shelter we bought three years ago was made from that type of board. Kept getting wet inside and couldn't figure out why but the board is compressed, shredded plastic, not a solid rolled sheet, and the upper sruface became rough and opened up, probably due to the weather, and rain would trickle through.  Walls still OK, but incredibly heavy and the open structure at the edges of the boards are definitely not red mite proof!

Thanks, that's helpful info. Will stick with ply and onduline I think.

I have thought of amending a 1ton tattie box.
You can usually pick them up cheaply from farms.
