A month of furlough in a week ahead and idle hands...
Has anyone built vertical board and batten? I'm a couple of miles from the fencing sawmill and I can get hold of 150mm x 19mm board cheaply. I've already used them to cover a retaining wall - it's robust and easy and looks good.
But it's heavy...
I'd also look at building carefully as I would need a few horizontal wall beams to nail into.
CLS seems cheapest framing?
Roofing - would metal sheet have huge amounts of condensation?
If I go plastic/onduline, how do you seal the edge of the wavy roof against flat timber?
I've got green Onduline on my shed roof and after 8 years it's starting to curl up at the edges and the colour has faded, it'll probably need replacing in the next couple of years. The shed is not insulated and I sometimes get condensation on the underside of the roof.
If I replace the roof I'll insulate it but not sure what I'll cover it with this time.
CLS framework is good, shrinkage of the boards will be an important factor, whatever you do take that into account , a dwarf wall, even 4 courses of brick will make it last almost forever if you can do it.
Roofing has a lot of options , Onduline from every long term review seems to be really poor , depending on the size/location I would look at polycarbonate sheeting , screw down bearers - don`t try click fix types without experienced help.
Pretty much the style of my last shed as was polebarn design due to a sloping site.
I went for board on board overlap. Got the first boards to fit as wide as I could at about 14" (less milling time if they aren't too automated and pre set). Then a bunch of 2" batten for covering the joins.
Also used onduline on the roof, sagged a little, but could have avoided this by spacing the batons closer as specified. You can get verge pieces, quick I used on the back, the sides I just rolled the corrugated around.
Current garage has metal corrugated roof as was quickest way to get it done and could have sheets cut to full length, but on the basis it is draft enough to not suffer condensation. Hopefully. Otherwise look at cement corrugated, quiter when rained on and no condensation, it's why they use it on animal sheds.
In terms of roof, you can get an EPDM kit fairly cheaply off ebay shops now, it's brilliant stuff.

+1 ...
I still like metal for a shed. Easy to fit (if you buy the right length), secure, then its its fit and forget. I got over the condensation by boarding the roof with OSB first, then some PIR insulation, then the metal. Might be overkill for your application but it really didn't cost much as I used second hand OSB and the PIR was bought as leftovers from a job.

That would/could be left to allow an airflow. When I replaced a stable roof with metal it came with cut foam infill pieces to block the gap but I've removed them to improve the airflow/reduce condensation.
We also reroofed the big (50' x 70') barn in steel and paid extra for the fleece lined sheets. The idea is that the condensation is held by the fleece and it then evaporates so no/less dripping. Over the 10 or so years it's been in there's been almost nothing in the way of drips so I'd say it works well.
Thanks all, good for for thoughts.
Another question - one side of my 'triangle with a blunt end' shape of shed has a 6' high wall down one side. It is a bit damp and I plan to leave a gap for airflow. The shed wall however doesn't need to be pretty.
Again I'm thinking a sheeting like onduline or wrinkly tin or fibreboard. Any thoughts?
