That really looks nice. It gives me some motivation, because my barn will be gambrel-roofed with a shed roof on one side, like yours. I'm even leaning towards the red color. I like your barn a lot!
One thing that I took notice of was how nice it looks with the metal siding. I was leaning towards hardi-plank on sheathing because I realy didn't like the look of the metal-sided buiildings I've seen. But, you've done such a nice job with the trim, etc., it really looks like a traditional wood-sided barn. With the cost of sheathing gone so high, you've given me something to think about. Did you insulate/finish the inside? If you get a chance, could you take a snap or two of what it looks like inside?
I'm not building a pole barn; mine will be stick-built on a monolithic slab with engineered trusses on 24" centers, one of the reasons being that it was easier to get engineered to the required 110 MPH wind load around here.
