Future Buildings 30 by 50 building. Never built, still on the trailer. Comes with insulation which is in dry storage. Listing this for my neighbor. He bought some land to put up the building and found out he couldn't put the building up so he sold the land. This building comes with the blueprints for construction. This is a new building.Forgot to mention the elevation of the building is 18 ft and the front of the building is open so you would need to build your own doors. I believe that is what the owner told me.
