We made the wall we made out of garden ties he had in another part of his yard. I think I have about $200 invested in it with materials. To fix any errors I had made so far I bought some 12 foot 2x4's to add some width to the shed base. When all the 2x10's are level (and square if you set the posts well) you can secure the 2x10's with carriage bolts. Joists are sometimes used to create a level deck to support bearers for a shop bought shed. In any case the most important thing is that the concrete can support the weight of the shed base, shed, and any snow, pine-needles, or leaves that land on it. Definitely a two-man job (or three), Those things are flimsy when they're half constructed, and the wind always starts just then...My Father-in-law has one the same as mine built one the ground and it's practically unusable (except for storage). Larger buildings are more difficult to plumb due to the amount of torque required to move the structure.

So now I had a shed 4 feet higher than it was intended which was great but I needed to fill that drafty 4 feet at the bottom. To cut the platform I first needed to remove the metal sill or transition that was at the bottom of the door. I concluded it'd take one person at least 4 times as long as it takes 2. The 2nd choice would be to use a slab, but this can get expensive since most pour cement with that much square footage, and is less time consuming than building a floor frame and plywood floor, but it most time consuming. The obvious answer is to raise the shed or lower the floor, and since the spot I wanted the shed to sit was sloped, I did a bit of both. Cheap doesn't mean you have to use low quality, but with proper planning, you can use quality materials. 11 years ago It really isn't hard but this is the critical step, you don't want a platform that is a different shape to your shed. With an additional 2' of height we can add 240sq' of storage area ! This is one of the best ways to stop a shed … Funny it never occurred to me to remove the old subfloor that is laying directly on the ground and then build a new subfloor on treated joists within the existing shed. A marvel of engineering they are! 5 years ago T1-11 or another type of plywood would probably have been better but the price was good enough for me to think, "If I have to replace it some time it won't be too hard". First off, NEVER put a slab over particle board, period. Reply

If she could get a few more years out of the structure by just doing something with the floor and painting, she would really like to. As I installed the skirting I remembered the need for a door so I opened the new shed doors as wide as they'd go and cut the platform and beam flush with the door posts. One thing I learned when I did it is don't ever attempt to put one together by myself. This is pretty easy (i'm hoping you have a level, I used a 48" one). The shed has a wood frame, and either particle board or plywood floor that unfortunately was placed directly on the ground. Good idea.

Mine has been up for a couple of years now and I'm really happy with it. Lets just say when I slapped it up I didn't call the building department. Also, paint the wood white - blend it all together for a nice clean look. So in short, choose a flooring system that will not only be inexpensive, but also durable over time, so you won't have worse issues to deal with, such as joists rotting (which can lead to structure collapse).

Going high with the wood will prevent water from rotting out the wood being so close to the ground.

Now to start scrounging materials........ Electrification & Restoration of a 1970's Raleigh Shopper. If you don't like the opening under the shed, build a skirt to cover the space between the shed floor and the ground. If the shed has an apex roof and its fastend down well put some strengh were the roof line meets inside. So I don't confuse you: I'm calling the 2X10's between the posts, "Beams" and the other 2X4's, "The Platform".The next important bit is that the platform is level. The one we did was really a two man job. If any of the posts are higher than the top face of the 2x10 it will need to be trimmed, or the 2x10's raised. We've been talking about another shed because our halloween  collection has outgrown the one we have and the christmas shed is almost as bad. 6 years ago Thanks for your question and welcome to the community. © Copyright 2020 Hearst Communications, Inc. Use mobile home ground anchors and straps if you live in an area prone to exceptionally high winds or if you have a large shed. High winds can easily topple garden sheds, and the resulting cleanup process from that happening can be long. Always one guy had to hold something up while the other one attached it.That is exactly it too, until the whole thing is together it is like a house of wet noodles, I can't even say house of cards, because it isn't that rigid. If you have a well drained ground where the shed floor should be, you can opt for gravel and paver stones if you wish, but it isn't the best choice if you use the shed a lot for foot traffic and withstanding oil spills, as an example. After the whole shed was built I screwed it down to the platform, doing it earlier would have made it very hard to line up the holes in the metal panels. on Introduction, I've been wanting to build a shed in the back for my fiance to work in. I wanted a solid starting point to measure from.I then set the other posts one by one, mainly since I only had an hour or so every few days.

Obviously to get the site flattened you have spent a little time thinking about layout. Aside from applying rust neutralizers on your metal shed, you may also want to waterproof it as well. where can u get the empty giant spools for free ,,like with nothing on them,, Reply

The only modification I had to make to my shed was to trim the metal that the sill was attached to with a hacksaw and trim the sill to easily fit the remaining gap so that I can replace it before closing the shed doors (they are sliding doors and require the channel to close). Just call around to "infrastructure cabling" companies.

That basically finished up this project. I built the shed right in front of my boss’s house and I wanted it to look nice. ... security light, and shed alarm, Baby listner type thing if you have mains power, This is the bit that sucks about this door: I cut a few inches off the U-channel and when I want to close the shed door I close the lower (wooden) doors then lay the shortened U-rail on top (the ends fit into the rails in the side walls) and slide the shed doors out into the groove. Some of the shed base was going to be underground so I wanted to add a bit of waterproofing and I had some black plastic poly sheet so I screwed down the 2x4's on top of the plastic then folded it out over the 2x4's and trimming the excess plastic afterwards. Mix up a bag of cement and pour it in the hole using a broom handle or piece of steel rod to tamp it down. This allows free flow of air beneath the shed and keeps the supports out of the damp. Your paver stone/gravel idea would only work if the base itself is exposed directly to the ground. Can you please explan better how you cut the channel for the door? I left this post for a day or so. This means if you like you can just dig four holes, set your posts and get started on the shed.

It is best to check the post several times during drying to make sure it stays plumb. Screw the ground anchors into the ground near the four corners, but along the long sides of the shed. Using 9mm plywood cut to match the roof supports then screw in place this should stop the shed swaying,put one on each joint Sorry my art works not very good hope this helps.

Then you can dig your holes. Start with any corner (better to pick the one that is most important to get right), drop in the 4x4 treated post and hold it plumb (straight up & down). Tie both ends of the strap to the tops of the two ground anchors that are on opposite sides of the shed from each other and closest to the front of the shed. With a simple square or rectangular shed you can easily measure and mark the spots to dig your post holes and double check the diagonals with the Pythagorean theorem. Surprisingly, the building has held up for at least 10 years. When I built the shed I left out the U-channel. My city allows sheds up to 150sq.ft. Repeat putting the second strap over the shed and tying it to the rear two ground anchors. This can take planning, but for up front labor costs and time, it can hold up for a very long time if constructed properly. Replacing the entire subfloor by building a base for the new slab is ideal. continue this all the way around the shed base, trimming the 2x10's to fit as needed. Posted 6 years ago. I helped a friend of mine put up a steel shed he bought at Sears. I have a couple of ideas but would like some expert input. The Federal Emergency Management Agency recommends homeowners in hurricane-prone regions use this method to secure their sheds, but you can use it wherever you live to thwart the damaging effects of the wind on your shed. I bought four 2"x10"x12' as flat, straight, untwisted, unbowed as the lumber store could produce (not treated as these are above the ground) and screwed the first one in so that the top face was just above the top of the post. Toss one of the straps over the roof of the shed. Then screw in the other end so that the top face is level. I'm thinking about undergoing a similar project right now. This is a realy good idea ! Retighten the first strap with the ratchet to match the tautness of the other strap.

However, water/moisture can easily damage floor joists (if there are any) over time. on Introduction, Reply I was thinking we could replace the baseboards and pour a slab maybe 2" thick. I have a friend looking for the least expensive and easiest way to replace or repair her shed floor and has asked for my help. I try to get each hole the size of a 80 pound pre-mix cement bag so that I can just buy 6 bags. My shed had two small metal rails for the bottom of the smaller walls beside the door, then a larger U-channel that bolts between these small rails to form the bottom door channel. Most would probably love to be rid of large spools if they have them... Not really a return value in them, at least in FL. This wasn't as hard as I thought but if there is a next time I would make the dirt floor a lot flatter before this step, the ladders were a bit wobbly while we screwed the roof together. Next I followed the manufacturer's instructions (basically) and build the shed on top of the 2x4 platform. on Introduction. on Step 8.

on Introduction. This was a terrible mistake which cost me several weekend afternoons inside the shed with a pick and shovel covered in dust with no wind to clear it away. Even indoor cabling firms do for a product called innerduct (plastic corrugated tubing they run fiber optic cables inside of). Thank you so much for the advice! I then used that wood and some more scrap to frame a couple of lower doors that I covered with the same siding that I had used for skirting.

We did sort of the same thing as you did, built a knee wall, then assembled the shed on it.

Joists are more versatile. 1. Water and moisture can easily trap underneath it, and would only work if not subfloor is there.

I'll use a leveling tool or something to see if I would need to do that.http://www.storageworld.com.au/Storage-units, 11 years ago A couple of years ago I decided I needed a shed so I started rough designing a wood framed one to work out pricing.

Of course I could have expended the posts up... also I needed to retain a  bit of backfill on two sides and I'm not sure the metal would have been stiff enough. on Introduction. This makes the holes about 12 inches square and 18 in.
