I'd use Viroc Versapanel, which is some sort of cement-based MDF and
works great for fascia boards and the like. It takes paint (cement
tolerant paints) but lasts well without it. It's about as stong as MDF
- I wouldn't walk on it, but thick slabs of it would probably be OK.
Drills easily but doesn't take screwthreads.

Wickes have their own version, and there's Aquapanel too which costs
more but is available in small pieces.

Thanks for the suggestion. I've not come across Versapanel, but it sounds
like it might do the job. Are BMs such as Jewsons and TP likely to stock it?

I'm also considering making a small lean-to tool shed, because none of the
plastic affairs stocked by the 'sheds' is quite the right size/shape. If I
make a wooden frame, would Versapanel be a suitable material with which to
clad it?
