Budget friendly and durable long lasting are not usually compatible. We set a lot of conexes, for anything from temporary storage, to people building houses and cabins out of them. Don't bury one in the dirt. I like the conexes with parking between, but if you want doors and out of the cold, pole barn or steel building. For 10 years, wood pole barn. Last 40 years, steel building. Last 80 years, concrete walls.
