Wed like to build a barn on the site of our old barn, and we need some input/advice. The building I have in mind would be a 30X20 barn with two levels. Our old barn has a slope where you could drive the combine around back and into the upper level. Id like to do something similar, but with maybe only a 10 roof up there, rather than the 20 of the old barn (we dont have acres of hay to store, only a tractor and goat and chicken feed!). Id like to have 2-3 sky lights and light panels on the sides of the barn. Im thinking metal standing-seam roof, downspouts, and 4 insulation. Does this sound right? Has anyone got suggestions for a manufacturer? The ones Ive looked at (Morton, Rhino) only seem to build enormous buildings; I dont think of our barn as enormous. Any ideas would be greatly appreciated!
