We are looking at self building both a lambing shed and also a workshop come machinery store.
Has anybody done this from online plans , my sons have extensive building experience but not designing or project management although i managed a complete house refurb a few years back of a derelict property, so i think given plans we can do this .
I am just struggling with where to source plans that will actually be worth what you pay for them.
We want a solid build concrete floor and then combination brick for lowest few foot then yorkshire board walls for air flow and tin roof to utilise a lot of quality older tin sheets we have and keep costs down. It’s in a shady area so the tin roof shouldn’t cause issues re heat and cold .
We will probably just build one building this year one next year and then possibly a joining hay  store stables design  type building in a few years time .
Other buildings are coming down that are rotten and dirt floor with oil and bits of metal buried in the floor so not suitable for animals and these new buildings are replacements .

Can't help with plans, I'm afraid, but just to comment that overheating is unlikely to be an issue when lambing, however just to bear in mind, anything which increases heat anywhere near a haystore would give me the heebie jeebies!
