Is the Classic Gambrel Large Barn the Storage Workhorse Your Property Needs?

Show more Show less

The Classic Gambrel Large Barn delivers large-capacity storage without taking over the yard. The gambrel roof buys you real vertical room for racking and loft boards, while the precut, labeled kit and 2×4 framing make assembly straight-forward with basic tools. Finish it to match your property and use it as overflow garage, lawn-and-garden HQ, or a clean spot for seasonal gear.

Benefits

• More usable volume, same footprint: The tall gambrel profile creates headroom for ladders, kayaks, and totes up high—so the floor stays clear for mowers, ATVs, or a workbench.
• DIY build that stays square: Precut, primed, and labeled parts reduce layout errors and trimming. Panels line up cleanly, fasteners bite well, and the shell stays rigid as you add shelves and hooks.
• Wide, equipment-friendly entry: Extra-wide double doors make it simple to roll in bulkier gear. No angle-jamming or taking attachments off just to park something inside.
• Durable exterior you can repaint: LP SmartSide® takes paint evenly, resists impact better than thin sheet metal, and lets you refresh color down the road without special prep.
• Finish locally, save on freight: Source shingles, drip edge, and paint near you—match your home and avoid paying to ship heavy, off-the-shelf items.
• Drier, better-ventilated interior: Built-in gable vents help move moisture out and protect tools and materials.

CUSTOMER PROVIDES:

• Shingles
• Drip Edge
• Paint
  
• Runners
• Floor (if the building is not purchased with a floor kit)
• If you will be preparing a cement/concrete slab, it would have to be exactly the same size as the unit. If the concrete slab is larger then you would have to trim the 3” skirting that falls below the bottom plate that is designed to wrap around the flooring.

The above items can easily be purchased by the customer at a local hardware store.

OPTIONAL FLOOR KIT:

• 2×4 treated floor joists – 16” O.C
• 5/8" plywood floor decking
• Note: 4×4 runners NOT included
• floor size should be exactly the same size as the building

If You're Building your own floor

• To build your own floor, the size of the floor will need to be the exact size of the Barn.
• We recommend a crushed stone base 1′ wider on either side of the Barn.
• The siding overlaps the side of the wood floor roughly 3″ and there is no moisture barrier. You can put this on a cement slab or wood floor – but accommodate for this
• You can retrofit for this but we do not provide instructions for this

Do I need a Floor Kit? This depends on your preference. If you are not getting a floor kit from us, you can either build your own floor or create a cement slab for your shed. Please take note that it should be exactly the same size as the shed.

(If you are using a slab as the floor then it needs to be the exact size of the building. If it's used as a foundation, then you can have it in any size.)

Additional Info:

Base: We recommend a crushed stone base, 1 foot wider than the building on all sides.

Flooring: Not included on some models. If you are building your own wood floor, it needs to be exactly the same size of the unit.
