I don't know if attaching PDF files works, but I'll give it a try.
I want to build a wind/rain shelter for my horses in the pasture and I'm wondering if my plan holds up. Note that I am an 0(1)8 and grew up in an apartment, but have been living in the countryside for 3 years now and am trying to fix and do a bit myself. A girl who hasn't had to build much before, but I'm thinking of changing that. I don't know how to draw blueprints and probably use the wrong terms and expressions, but I hope you'll understand anyway.
The drawing is only for the frame, and of course the roof should rest on more beams than shown, but I couldn't figure out how to draw it clearly.
Another consideration is whether untreated timber can be used for this and do what is done with timber on barns, etc., i.e., paint everything with red Falu Rödfärg (first prime with a little diluted paint and then apply 1-2 coats all around).
The idea is for this to withstand a horse weighing 5-600kg leaning and scratching its rump against the structure.
It looks stable, but you should probably add the braces (angled beams from one upper corner to the opposite lower corner) on each "opening" (=4 pieces).
Then you can have pressure-treated wood, but you need to wait a year or so before painting.
Do you mean 4 pieces in total (i.e., one crossbar per opening) or do you mean as a full cross (so there are 4 "subsections") per opening? See my new attached file - like the pink or like the pink+green?
I would prefer to avoid using pressure-treated wood (because I'm a bit frugal and have found a local guy who sells studs at very good prices), so the question was if I can use regular lumber and paint instead of using impregnated/pressure-treated.
I think cross braces will be redundant, but just so you have them on the gables as well.
Regular timber works just as well. You have a roof, so it'll take time before it's damaged. Try to get the posts a bit off the ground so rain and snow don't accumulate, and it will last longer..
