Has anyone on here put up a metal building (indoor). What were your dimensions and cost? I'm interested in an 80x150.

Better dig deep into those pockets for that size.  60' x 100' red iron with just roof and 1 wall (100') about $80,000.  That is just red iron, sheet metal and concrete footing and piers.  No ground prep or electric included.

I should add that is 14' side walls.  Just having the north wall for a wind break makes a lot of difference in our part of the country

At $40/sq ft, (about the going price here), that's $480K. Going to vary wildly though. How many doors? Full metal framing or maybe use wood where possible? Insulated or not.  And ht? That's a big one. After you draw up your plans get estimates and be sure to use a contractor that's built what you want before. You don't want a building contractor that this is their first time building your kind of structure. 

6 yrs ago i built an 80 x 80 all metal building, 15' sides, 1 roll up door on 3 sides. It cost $90,000, including piers and pad. I thought i would get spray insulation in later ($24,000) but haven't. Thought I'd put in a BigAss fan ($6500) but I haven't. Electrical and lights was $3500. A pole barn would've been cheaper but I'm in OK and wanted something that would hold up thru win, etc 

the building is small but i can get a lot done in it when the weather's bad outside, plus, its what I could afford ;-)
