I looked at metal buildings, pole barns and all sorts of combinations, but I just couldn't find what I wanted. It has to look nice, complement the house, have 12' clearance in the shop, have plenty of loft storage, and room for my home office up in the loft.
I ended up going with
BarnPlans.com, run by a fellow from Hawaii who loves gambrel roofed barns and obviously loves his work. I bought the plans for a 32'x40' similar to the one pictured in the attachment. The 32' is fixed, but the length can be stretched in 2' intervals. If my budget can stand it, I plan on 32'x48' with a full loft. The gambrel roof makes the second floor storage much more useful. The siding will be HardiPlank and the roof will be galvalume 5V crimp.
I'm also planning to add a 16' shed roof to one side of the barn, along the full length, for storage of implements, a couple of project cars, etc. that don't need to be inside. I'll have a fabrication shop, maintenance area, tools and parts storage, a lift, and a spot for our race car.
I have the plans (they look good), and, if the county will let me build a barn/shop before the house (I think they will, it's a rural area and the rules aren't as strict), I'll be starting construction within a few weeks, after the clearing is complete. I plan to do most of it myself, but have a son and son-in-law plus a couple of friends who want to help. While BarnPlans includes plans for building the trusses, I'll have a local truss factory make them, and rent a crane service to install them. It will be build on a slab, for which I'll hire a subcontractor.
I've been remodeling, rewiring, replumbing, and fabricating things all my life, but I have never built a barn or house before. Should be an interesting experience.
