Features

  • A Crucial Note on Installation: For rock-solid, permanent stability, securing this shed to a concrete foundation using the provided anchors is highly advised. For installation on non-paved ground (like soil or gravel), the separate purchase of heavy-duty auger anchors is required. To ensure a secure grip that bypasses the frost line and prevents shifting, we specify anchors of at least 30-36 inches (75-90 cm) in length.
  • Reclaim Your Property with 260 sq. ft. of Vast Storage: Finally, the space you've been dreaming of. This 13x20ft metal building offers an immense area, perfectly suited as a protective car garage, a creative workshop, or a central hub for all your outdoor storage needs. Thanks to an impressive 8 ft peak clearance and an oversized double-door entrance, maneuvering your vehicle, boat, or large equipment inside is effortless.
  • Built Like a Fortress with an Unyielding Truss System: This is engineered for year-round peace of mind. Crafted from heavy-duty (23 gauge), multi-coated galvanized steel, its structural backbone is a unique, double-reinforced internal truss and beam system (18 Gauge). This robust design confidently stands up to extreme weather, from high winds to heavy snow loads, providing a permanent, all-weather shield for your valuable assets.
  • Naturally Lit & Freshly Ventilated Interior: Step into a workspace thats bright and airy, without needing to flip a switch. This shed features four strategically placed polycarbonate skylight panels that flood the interior with natural daylight. Paired with four integrated vents that provide excellent cross-ventilation, it effectively prevents dampness and stale air, creating a healthy and pleasant environment for any task.
  • Smart Dual-Entry for Ultimate Access & Security: Experience superior functionality with two points of entry. A wide front double door provides easy access for vehicles and bulky equipment, while a separate personal side door allows for quick, convenient walk-in access. Both entrances are fully lockable with the included anti-theft hardware, ensuring your workshop or motorcycle garage remains secure.

  • Decent Shed, Watch Video and Instructions make more sense
Style: 12x10′
Over all, once the frame is all together the shed get very sturdy. The frame is thick and heavy. The walls connect to the bottom frame, a center frame and a top frame. So you have 3 structure supports for the walls. Then the main frame locks this all in. Instructions are decent. Not the best, but there is a video right here in the advertisement, that will basically make the instructions very simple. Just make sure you are level. Do NOT bolt the frame down until your done. If the holes don't line up, you just need to move a corner a little. Took 3 of us about 2 days. (Day 1: walls and frame and door frame.. Day 2 is roof, windows and doors) I still have to put the roof and doors on. Running out of daylight now, but we did check and all the holes line up. I will have an updated image when it's complete. But so far, very happy with it. I put mine on 4x6 Pressure wood. Added some netting stuff and poured rock for the inside. (Shed is not sitting on rock). Once this is completed, I will level the rock out and use that rock glue. See how that works. Update. Roof and doors are on. No issues with the roof either. Had 2 small leaks with heavy rain. Ran a little calking on that area 2 - 2" beads and no leaks now. ... show more

  • Wear the gloves that come with the kit and read instructions carefully
Style: 10×12′
If you are a capable person and have ALOT patience, also have a helper with those same qualities this shed is totally do-able. It will take you 2 full days to construct. If your not willing to spend an entire weekend for assembly just buy one that's already constructed. Once its assembled it's a great little shed for the price. You have to be careful when assembling as the tin is pretty flimsy but it all comes together and makes for a pretty sturdy shed. Instructions are not the best, but take your time and you'll be fine. ... show more

  • Don't start until you have all boxes like it states.
Style: 10x10′ with Base Kit
This was a fun build. I used my own hardware. Everything held together by nuts and bolts and panels sealed on overlap with construction adhesive. I overbuilt this thing a lil bit but it's solid.

  • Good shed for the price
Style: 12x10′
It's easy to pot together. Not enough screws. Leaks around the floor. Plan on caulking it

  • Not happy with directions
Style: 10x12′ with Base Kit
Directions are sketchy at best. Predrilled holes do not always line up. Had to redrill many of the holes on the bottom of the wall panels.

  • Think before buying
Style: 10×16′ with Base Kit
Most pieces were dented even though the boxes weren’t dented. Holes did not line up and very poor instructions

  • Husband shed
Style: 12x10′
I am must say that this shed is really nice. It’s dirty. The price was right. It was easy for my husband to put up by himself. There was no missing parts and we love the fact that it has skylights. We did buy tiedowns because we are in a state that gets those storms.
