Keystone Construction LLC

Keystone Construction LLC is a post-frame builder headquartered in Elkton, Kentucky, with a second office in Goodlettsville, Tennessee. Founded in 2005, the company reports more than 2,000 buildings completed across personal, residential, and commercial uses. Its lineup covers barndominiums, garages, workshops, commercial structures, agricultural buildings, and equestrian facilities, and it offers both shell and turnkey options, so a barndominium buyer can order a closed-in structure or a fuller build.

Service territory covers Kentucky and Tennessee. Keystone runs a 7-step construction sequence: excavation, setting posts, framing, setting trusses, roofing, siding, and concrete work. Projects typically begin 4 to 10 weeks after contract signing, with completion time depending on building size and selected options.

Wall and roof assembly uses galvanized nails, screws, and rubber washers. Customers can model their building with an online 3D customization tool before signing, and financing options are available. The company has been featured as a barndominium expert by Redfin, and at the time of review it listed a completed barndominium for sale near Clarksville, Tennessee, which gives shoppers a way to see finished work firsthand.

Customer testimonials on the site center on build quality and professionalism through the process.
