12x40 Garden Shed

Want the biggest in this range? The 12x40 Garden Shed delivers supreme storage with a smart layout. Large double doors offer easy entry for hefty items, and two windows keep it bright and airy. With 7’8” walls, it’s built tall and tough.

Crafted by Amish hands, it uses pressure-treated wood to resist pests and decay, aluminum drip edges to block moisture, and galvanized nails for rust-free durability. Pick treated, urethane, or painted finishes to match your style. Ideal for huge storage needs, equipment, or a grand workspace, this shed excels. Order now for unmatched Amish quality!

How It's Built

Amish Crew Construction

Built by Amish crews in Topeka, Indiana, and Colon, Michigan, with no subcontractor handoff.

Garden Shed Door Package

Transom windows and upgraded door details give the shed a more finished backyard look than a basic storage box.

Legacy Floor Decking

3/4" tongue-and-groove Legacy decking supports tools, mowers, bins, and everyday storage.

LP SmartSide Standard

LP SmartSide siding gives the shed a paintable, durable exterior built for long-term outdoor use.

Siding Options — 3 Available

LP SmartSide engineered-wood lap siding close-up

LP SmartSide

  • Zinc borate treatment resists decay, fungal growth, and termites.

  • 20 standard colors painted at the Homestead Barns shop, plus custom color matching available.

  • 5/50-year manufacturer warranty from LP — one of the strongest in the industry.

Painted vertical metal siding close-up

29 Gauge Metal

  • Color is baked into the steel at the factory, not painted on. Won’t fade, peel, or chalk.

  • Won’t rot, attract termites, or burn. Stands up to hail and Michigan winters.

  • 40+ year service life with zero painting, zero caulking, zero maintenance.

Horizontal vinyl lap siding close-up

Vinyl

  • Dutch Lap profile with weathered woodgrain texture and UV inhibitors.

  • 1/2-inch profile depth for rigidity — won’t peel, flake, blister, or rot.

  • Hose it off once a year and it looks like new.

Roofing Options — 2 Available

Standing-seam metal roof close-up

29 Gauge Metal

  • Same Galvalume-coated steel as the metal siding — built to last decades.

  • Sheds snow and rain fast; works on steep or low-slope pitches.

  • 40+ year lifespan under normal conditions with minimal upkeep.

Architectural dimensional shingles close-up

Shingles

  • Architectural-grade asphalt in a wide range of colors to match your home.

  • Algae-resistant coating keeps the roof looking clean over time.

  • Proven performance in Michigan weather at an accessible price point.

Material pricing varies based on current market conditions and regional availability. All options are built to the same structural standards by our Amish craftsmen.
