Built my 50x30 in 2014.....

Used Allied Steel......24 gauge sheeting

IIRC...complete pkg with R19 batting was $17K shipped

About the same for concrete...don't forget the 24" stem wall

one man door.....I supplied windows & OH doors

Money well spent....NG radiant tube heat keeps 'er at 67* all winter
