How to Build a Storage Shed from Scratch (Phase 1)

Learn how to build a storage shed from the ground up with this easy tutorial. These steps will show you how to create your shed design, prepare for construction, and build the floors and walls – along with some money-saving tips!

With a larger house comes a bigger yard. I knew my little push lawn mower could only do so much with half an acre.

This was proven true after nearly 3 hours mowing the grass, and stopping to empty the bag every 2 minutes. I couldn’t believe how much time it would take me to maintain the lawn each week.

Because of this, I bought a used riding mower that sped things up significantly, as I can now finish cutting the lawn in just over half an hour.

However, the behemoth was taking up half our garage. The riding lawn mower was huge, and we couldn’t get the car into the garage along with it. 

I had big plans for our new garage (tons of workbenches and storage ideas).

As much as I loved my new riding mower, its home was not going to be the garage.

This was an excellent opportunity to work on my dream shed project – teaching myself how to build a storage shed. 

How to Build a Storage Shed - Easy Tutorial for DIYers

How to Build a Shed Series

This post is part of a three-part series that I wrote on how I built my shed from the ground up.

I’m including so many details of how I built it, tips and tricks I did, mistakes I made, and all the how-tos.

I’m breaking it into three posts because of the amount of details.

In this post, I will show you the shed design process, how to prepare for construction, how to build the floor and walls, and how to install the doors and window headers.

My next article will show you phase two of the shed building process, which is how to install shed siding and roofing. This is when you really see the shed take shape.

And, my third article will show you phase three of how to build a shed, which covers how to build steps for the shed, a ramp for the shed, and custom shed doors. The doors involve an easy custom design that my wife swooned over. 

Storage Shed Plans and Designs

I worked on building the DIY storage shed single-handedly over the summer.

I wasn’t sure that building a shed was in my skill set, especially building it by myself. Never had I done anything like this before.

However, I did a lot of research, watched a lot of videos, and asked some contractor gurus for advice.

The result?

An amazing DIY storage shed that my wife still can’t believe I built.

Did I make mistakes? Of course, but I learned from them and am sharing it all with you – so you can learn too.

If you are wondering how to build a storage shed or if building a shed from scratch is within your skill set, keep reading this DIY shed tutorial. 

Choosing a Storage Shed Design

In learning how to build a storage shed, the first thing I had to do was decide on a shed design and plans.

Now if I was going to build a shed, I wanted it to be multi-functional and not just mower storage.

I went over several ideas in my head about how I could use the new storage in the shed.

I initially thought it would be nice to have an area of the DIY shed to store bagged lawn clippings and keep it dry from the rain.

It was annoying trying to handle soaking wet yard waste bags once exposed to the elements all week.

I also wanted to remove some of the bulkier items from the garage (like the wheelbarrow and fertilizer spreader), so the storage shed needed to be large enough to accommodate these things.

After taking measurements of the riding mower, I padded the size to include additional storage. I settled on a 10 x 16 shed plan.

This would give me ample space to park the mower and store gardening equipment and large tools.

Picturing the End Product

When planning things out, I usually like picturing the end product and doing a walk-through in my head to make sure everything makes practical sense.

I envisioned myself driving the mower into the storage shed, stepping off to the left (bagging chute was on the right), and walking out the shed door.

I knew I wanted the mower entrance to be on the far end, and shed storage directly adjacent.

Now if I stepped off to the left of the mower, I didn’t want to be walking into a wall.

I thought it would be a tight squeeze to fit between the mower and the wall, so I wanted to place the mower entrance on the right size of the shed.

Deciding on Storage Shed Plans

With the basic requirements of how to build a storage shed in mind, I started shopping online for storage shed plans.

There are lots of sites online selling plans for custom built storage sheds.

I ended up going with www.icreatables.com

They had designs more to my personal liking, and they also had a ton of resources (video walk-throughs of storage shed constructions) which I found very helpful.

I found a “Cape Cod” shed design that I liked a lot. It came with a large overhang that would be perfect for keeping rain out of my bagged yard waste.

I just needed to add a deck to make a little porch on the storage shed to elevate my bags off the ground.

First Shed Sketch

Learn how to build a DIY storage shed with these designs and plans

Here’s my first sketch of the DIY shed. It’s a rough sketch, but this is how all my projects start, with putting a vision to paper. 

As you can see in the picture, I have the mower entrance on the far right, and a porch on the rear for storing bags of lawn clippings.

I also added a smaller door on the side of the shed to easily access the storage area of the shed.

Two windows were sufficient to let in enough lighting. I also factored in a ramp for the mower.

Don’t let the 12 x 16 dimensions fool you. The extra two feet was accounting for the overhang, so the storage shed plan was still 10 x 16.

The shed foundation was going to rest on some 4 x 4 skids, sitting on 18 concrete blocks.

I did look into concrete anchors, but opted for the skid design due to simplicity.

Also a majority of comparable storage sheds in my area were resting on skids, so that gave me confidence that I was making the right decision.

I knew I was not in a flood zone either. If this were the case, I would have had to anchor the DIY shed permanently.

I purchased the storage shed plans for $15 and started going over the material list and putting together a cost estimate.

Preparing for Construction

Moving on to the construction part of how to build a shed!

This part of the storage shed construction took quite some time as I had no experience in construction of this magnitude.

Research

I had to google lots of techniques and terminology while going through the storage shed plans.

Also, I can’t tell you how much of a resource youtube was for me.

With each part of the shed construction process in the plans,  I had to picture myself actually doing the work.

This helped me know if it was within my skill set and if I had the correct equipment.

I did have to purchase a number of tools to complete the shed project, but I’ll get to those in a bit.

After mulling over the storage shed plans and materials, I hit a snag.

To accomplish the two feet roof overhang, I needed a 16ft LVL (laminated veneer lumber) beam.

This is essentially a really strong, hard, and heavy piece of wood running across the underside of the overhang.

It needed to be strong enough to handle the weight of the shed’s roof.

Unfortunately, the storage shed plans called for a certain size LVL beam that was really expensive for me and was not available at the local Home Depot.

I considered making my own beam, but abandoned this idea out of lack of experience. The last thing I wanted to do was make something unsafe.

Second Shed Sketch

At this point, I was also getting a little overwhelmed at the construction design of the overhang.

This was a turning point in my shed project.

So teaching myself how to build a storage shed, I ended up abandoning the overhang design and opting for a more traditional shed.

This meant ditching the storage of the yard waste bags.  

It wasn’t such a terrible loss. If I really wanted to, I could construct a box with a flap at the top to store the bags in.

So, I browsed through more shed designs and bought a simpler one for another $15.

After some tweaks to the purchased plans, here was the final design I ended up going with:

How to Build a Shed from Scratch - Initial Sketch

That sketch needed a bit of explanation as it does look a lot different than my original idea and went against my initial plan of the mower entrance being on the far right.

How to Build a Storage Shed

At this point in the shed project, I had already started doing some of the prep work outside that was not going to change, regardless of the shed design.

Laying Concrete Blocks for the Skids

Specifically, I laid out the 18 concrete blocks for the skids and worked on getting them leveled properly for the storage shed (see pictures below).

Build your own DIY backyard storage shed with this easy to follow tutorialTip for Leveling Skids

Here’s a small tip about leveling the skids for a storage shed.

Even though I tried my best to get the concrete blocks perfectly level, there were a few that were off by a little. This is pretty typical.

This left a gap when the skids were rested on them.

How to Build a Shed from Scratch with this simple tutorial

So to fill the gaps, I used scraps of roofing shingles. I read this shed tip online, and it helped me out a lot.
After leveling off the concrete blocks and placing the 4 x 4 skids on them, it became very apparent that as flat as the yard looked, there was a subtle slope.

This made the right side of the shed about a foot higher off the ground than the left side.

This made it very inconvenient to have the shed ramp on the right side.

It meant I would need a much bigger ramp (more materials and expense).

Also, that extra foot of height was making me nervous about driving the mower up it.

How simple it would be to just have the ramp on the left side of the storage shed, where the ground height was minimal.

Adjusting the Shed Design

So, in my DIY shed design, I relocated the mower entrance.

I did some more measurements and decided that the squeeze between the mower and the wall (when exiting the mower on the left) would not be so bad.

Nonetheless, I still kept my fingers crossed it would work out. Also, I had to relocate the storage shed entrance door since that was where the mower was going to park.

I did have to add some steps into my shed design to accommodate the big drop from the door to the ground now.

Additionally, I moved the windows around in my shed plans. The windows are on the front right corner now.

It all worked out for the best as this was the optimal setup to allow the most sunlight in.

My yard has lots of big trees, and most of the storage shed is usually under tree shade.

As you can tell in the picture with the 4 x 4 skids, I get the most sunlight from the right side of the shed so relocating the windows to the right made the most sense.

Happy with the new design, I was excited to my DIY shed project – as I was making some good progress constructing the storage shed.

Ordering the Shed Materials

One of the most exciting and anticipated moments in the project was getting the Home Depot delivery of materials.

For $75 delivery fee, Home Depot dropped off a gigantic pile of lumber for the storage shed on my driveway. It was definitely worth the delivery because it was a ton of materials.

With my wife’s help, it only took a couple of hours to relocate the lumber into my garage to keep it save from the weather.

It was also very fitting that it happened to be our 5th year wedding anniversary, and wood is the appointed gift for 5 years!

So happy anniversary my dear – wood!

Anyway, prior to ordering, I made a saved list called “Storage Shed” on Home Depot’s website, and added all the materials I needed.

Money-Saving Tips for Building Sheds

The total came to around $2000.

I was able to knock off an extra $250 though, and here’s how. Ebay has lots of 10% off coupons for Home Depot (up to $200 off).

I’ve come to realize that these coupons are hard to get a hold of for free. They typically sell for around $35 on ebay.

This was a bargain for me because that $35 that I would spend on the coupon would save me $200 off my storage shed cost.

Incidentally, the day I was going to purchase the coupon on ebay, I checked my mailbox and saw a bright yellow letter from Home Depot.

I knew instantly what it was – a 10% off coupon!

What were the odds? We just moved into our new home a few months prior, and Home Depot sent us a coupon congratulating us on our move.

Well, we saved another $35.

If you aren’t as lucky as me, buy the coupon on ebay for your project, if it makes sense for your budget.

For the other $50 I saved – I used ebay.  

I was able to purchase 2 gift cards on ebay worth $500 each, but selling for $475 each.

I hope some of these money-saving tips can help you save with your shed.

How to Build a Shed Foundation

The next step in learning how to build a shed is to work on the shed foundation. I made the skids out of 6 pieces of 4 x 4 x 8 pressure-treated wood.

Safety First

Just a little note about working safely. Pretty much all wood used in the storage shed was pressure treated, by the way.

The wood was treated with a special chemical to keep bugs (and moisture to some degree) out.

When building outdoor structures, you really need pressure-treated wood.

A word of caution though, be careful about splinters and sawdust from cutting.

Splinters on the skin might sting or give a rash because of the chemicals.

Also, wear a dust mask when cutting the wood. You don’t want to be inhaling chemically treated sawdust.

Framing the Floor Joists

For the storage shed skids, I needed each of the 3 rows to be 16 ft long, so I joined 2 of the 8 ft pieces with a mending plate.

Building a Storage Shed is simple with this DIY tutorial

With the 4 x 4 skids now in place, I finally had a platform to start erecting the storage shed.  I followed the directions in the plans to frame the floor joists (see picture).
Looks awesome, right? After framing the floor joists, I secured it to the 4 x 4 skids with some L brackets.

Why You Need a Framing Nail Gun

Also, do you see my framing nail gun on the right hand side? I could not have built the shed without it.

I highly recommend this framing nail gun for building large structures like this shed.

The specific gun I have is a Paslode gas framing gun. I bought a used one on ebay for $100.

They normally retail for several hundred dollars, so it was a great deal.

I did have to buy a cleaning kit for the framing nail gun though because the nails were starting to jam after repeated use.

Gas framing nail guns are the way to go if you don’t have a pneumatic compressor.

They use a special butane fuel cell (a small cylindrical cartridge you insert into the back) and a rechargeable battery.

The nail gun ignites some of the butane to fire a piston forward and drive the nail in.

The framing nail gun is really powerful (and dangerous if you’re not careful) and makes framing wooden structures a breeze.

This is the one tool that I couldn’t have built my shed without. 

How to Build a Shed Floor

Here’s my framing nail gun and me:

How to Build a Shed Floor

In learning how to build a storage shed, the next step was the actual shed floor. I was making progress!

I used several 4 x 8 sheets of ¾” T&G orient strand board, following the sheeting patterns in the plans.

The T&G stands for tongue and groove.

One end of the board has a protruding strip called the tongue, while the other end of the board has a groove.

The tongue of one sheet is meant to be inserted into the groove of the next sheet, interlocking them together.

Once nailed down to the floor joists, the T&G system made a very sturdy floor for my shed.

I also applied a deck finish to the floor to protect it from water.

I knew it was going to be a while before the shed roof was installed, so waterproofing the shed floor was a high-priority (see below picture).

Laying the foundation of the DIY shedHow to Build Shed Walls

After securing the shed floor to the foundation, the next step was to frame and erect the walls.

I followed the plans carefully and cut all the 2 x 4s to proper lengths in preparation for building the shed walls.

First Two Panels

The large shed floor was a perfect platform to build the wall panels on. (You can see I started assembling a wall in the last picture.)

After finishing a wall section, I stood it up, carefully aligned it with the edge of the floor, and nailed it into the floor joists.

The 10 ft side panel went up first and was easy to raise and nail by myself. However, I needed some help raising the long 16 ft panel.

It was very heavy and wobbly to work with by myself.

Once in position, I secured it to the floor and then to the 10 ft panel already standing up.

At this point, I thought it would be a good idea to use L brackets to more securely join the two wall panels.

So I installed 5 brackets.

This held the panels very tightly in place. I repeated this technique for the rest of the panel installation.

However, this idea backfired a little later in the project (I’ll get to that when I tell you about installing the exterior siding).

The L brackets were a good idea, but unfortunately not this early in the project.

I finished the panel installation.

I installed some temporary supports to the open end of the panels to give some rigidity until more panels were installed (see picture).

Building the wall panels for the DIY shed

Last Two Panels

The two remaining wall panels took me more time to build, as they were more complicated in design.

They had openings for windows and doors, which meant building and installing headers.

Remember how I had purchased 2 separate plans in the beginning of the project? It actually worked well for me.

The second plan (which I was basing my shed off) did not include any windows or a small door frame.

However, the first plan (with the overhanging roof) had both of those things.

So I merged the plans to create what I had in mind for my shed.

How to Install Door and Window Headers

​Next up in my building a storage shed project was installing the door and window headers.

During the construction of the wall panels, I had to install headers above each door and window opening.

Building Headers

When you have a large opening in your wall frame, there is no vertical support.

So there’s nothing to help bear to load of the roof.

You have to install a strong beam above the opening.

This will transfer the roof load horizontally and then down the sides of your opening. This beam is called a header.

I built my own headers by nailing 3 layers of wood together.

I sandwiched a strip of plywood between two pieces of 2 x 6 and it made a very strong beam.

Here is the shed with all four wall panels up.

Install wall panels on the DIY shed

Not bad for someone teaching himself how to build a storage shed.
Ignore the windows that are mounted in the frame.

I will install the windows later, but I was eager to see what they would look like mounted.

I removed them shortly afterwards to continue shed construction.

Installing wall panels on the DIY shed - learning to build your own shedPhase One – Finished!

My shed project was really starting to take shape at this point.

Even though my original design changed a few times and I originally questioned my skills, it was coming along great!

It looked like a professionally-constructed building and I was thrilled with my ability to do this. It took a lot of planning, preparation, and time to get this far, but I was pleased.

If you are wondering how to build a storage shed or if it is within your skill set, this tutorial will definitely set you on your way.

The second part of How to Build a Storage Shed is continued here – Shed Project Part 2. In that post, I’ll show you how I did the shed siding and roofing!

And, the last part of the series will show you how to do the steps, ramps, and custom doors.

Keep following along, so I can show you the end result – a professional-looking shed for a fraction of the cost.

    1. From start to finish, it may seem a little intimidating, but just take it one step at a time. The nice thing about building a shed is that it starts off easy (layout the foundation, building the floor, etc.), and by the time you get to some of the more daunting tasks (like the roof), you would have gained a lot of confidence/experience working your way to that point.

  4. Nice job! We just installed a shed, too. It’s so nice to have all our yard tools out of the garage! 🙂

  15. Which shed plans did you use from icreate? I need the double doors and single door to be on the same side of the building – exactly like yours.

    1. Hi, on ICreatables.com, I used the “10×16 Cape Cod Shed Plans”. However, I manually adjusted the plans to move the doors to the same side, and re-positioned the windows. Unfortunately, I don’t have a picture of the updated plans, but it wasn’t that hard to do.
