Material Cost To Build A 12×20 Shed

The 12×20 Shed is an easy-to-build, cost-effective shed that is perfect for storing your lawnmower, garden tools, and other outdoor equipment.

This shed is built with framing lumber and is made with 2×6 pressure-treated plywood. The flooring is constructed with 2×4 tongue and groove deck boards. The side walls are made with 2x4s attached to the inside of the frame with vinyl-coated screws.

The roof rafters are constructed using 2×6 pressure-treated lumber attached to the top of each wall using vinyl-coated screws. The roofing material is 3/8″ CDX plywood sheets attached to the rafters with nails or screws.

When you are looking to build a 12×20 shed, there are many things that need to be taken into consideration. This is not just because of the materials needed but also the experience level of the person doing it as well as how much money they want to spend on it. If you were going to build this yourself, then I would recommend using pressure-treated lumber because it will last longer than regular wood due to its higher quality but make sure that if you do use this type then its been stored in a dry location beforehand since moisture can cause decay due to fungus growth once it comes into contact with oxygen within our atmosphere after being cut down from trees growing out in nature from where it was originally planted there by Mother Nature herself decades ago before any human beings came along taking away all their land from them which makes me wonder why we do such things like that now when we know what will happen if we continue doing so (humanity is destroying ourselves with our own technology)…

In order to get a very accurate cost to build a 12×20 shed, you need to know item by item the materials that you will be using. You also need to make sure that you have the right amount of materials for the space that your shed will take up. It is important that you get everything right because if not, this could cause other problems later on in the process. If you are unsure about any parts of your project or think it would be best for someone else to do it, then it might be a good idea for them to look into cost estimates from professionals in their area so they can ensure they have everything covered before moving forward with their plans.

Below is an example list of materials used to build this specific shed.

If you are interested in building your own 12×20 shed, here’s an example list of materials used to build this specific one.

Total cost: $2,250

  • Materials (not including labor) $1,845
  • Tools $325
  • Labor $400
  • Taxes + permits $150

It may not be of much use in the long run but it will give you an idea of how much it costs to build a 12×20 shed.

To give you a general idea of how much it costs to build a 12×20 shed, the following list is a good place to start.

  • Approximately $2,500 for materials
  • If you are close enough to pick up the materials yourself, then it could be less than that. However, if you live in a rural area where everything has to be delivered by truck then this cost could go up quite a bit.
  • There’s no need to hire outside help unless you’re doing this project as part of an insurance claim after some damage caused by a natural disaster (tornado/hurricane). In fact, building your own shed can actually teach many life lessons like patience and perseverance.

The following is just an estimate, if you live in a very rural area then the price can go up quite a bit depending on your location.

This is just an estimate, but if you live in a very rural area then the price can go up quite a bit depending on your location. The reason for this is that there are things such as transportation costs that need to be factored in when figuring out how much it will cost you to build your 12×20 shed. This can also vary greatly based on how much material you need, what type of materials you choose and whether or not someone else will be helping you.

Skid Foundation

A skid foundation is a wood foundation that is less expensive than concrete, but not as strong. The wood can be pine, cedar, or treated lumber. Skid foundations are easy to install and are commonly used for sheds, garages, and other buildings.

Floor Joists and Decking

The floor joists and decking are the two most expensive parts of your shed. This is where you will spend a lot of money, so make sure that you get the right materials for each job.

To start with, you will need to buy eight 2x4s for the floor joists. These boards will be connected together using metal brackets called joist hangers. The cost of these brackets can vary greatly depending on where you purchase them from and how many pieces are needed for your project. You’ll also need 16 more 2x4s to create a sturdy base for your shed’s foundation (we’ll discuss this further in Step 1).

The decking material used here was pine planks that were about ¾ inch thick (1½ cm). There are alternatives that might cost less or be easier to work with than pine planks, for example, cedar lumber costs slightly more than pine but tends not only to last longer but also provides better protection against rot as well as termites; alternatively though if budget isn’t an issue then treat yourself with some beautiful redwood instead.

Wall Framing

The most expensive part of building a shed is the framing. For this reason, it’s important to think carefully about how you construct the walls and roof because they will make up a large portion of your budget.

The first step in determining your wall construction is to decide whether or not you want to use 2x4s or 2x6s for framing. If you choose 2x4s, that means each stud will be one inch thick by four inches wide; if you choose 2x6s, each stud will be one inch thick by six inches wide, and that extra two inch provides better support for larger projects like sheds. Additionally, if any of your walls will be exposed to moisture (like those near windows) then using 2x6s is recommended because they’re less prone to rotting than their thinner counterparts.

Using these guidelines plus a few other tips can help keep costs down while still making sure everything meets code requirements:

  • Use metal nails instead of wood screws whenever possible so they don’t leave holes in the wood when they’re removed later on down the road; if there aren’t any metal nails available at local hardware stores then consider buying them online before starting construction work on anything major (this way it won’t take long after ordering them before arriving via mail).
  • Use pressure-treated lumber whenever possible because although it doesn’t come cheap ($20 per board), its longevity makes up for its high cost over time since no maintenance has been required since installation occurred several years ago.”

Roof Framing

You will need to frame your roof with a truss system. A truss is a structural system that allows you to build the roof as one unit, rather than assembling many smaller pieces of wood as you would with rafters and joists. The most common type of truss used in residential construction today is built using plywood and 2x4s (or 4x4s).

Trusses are not difficult to assemble, but they do require some special equipment: a framing square, a tape measure, and pencil, a nail gun or hammer, and nails or a pneumatic stapler (a power drill may also be helpful). You’ll also need some help from an assistant, the trusses weigh around 100 pounds each.

Roof Sheathing

It’s time to get serious about sheathing the roof. The sheathing is a thin layer of material that covers the entire roof, protecting it from above and below. The purpose of this step is to keep water out of your shed and prevent rot from occurring within its core.

In order for a roofing supply company (or an online retailer) to quote you on your project, they’ll need the dimensions of your shed in feet and inches, as well as its pitch (the slope). They will also need at least an idea of what kind of materials they’d like to use for sheathing (see below). If you’re going with something custom or don’t know enough about them yet, make sure they have some paper samples on hand so that they can physically show you how their product looks before making any commitments.


Siding is the exterior covering of a building, often referred to as cladding. Siding can be made from many different materials, including wood, vinyl, aluminum, and fiber cement. Siding can be installed in different ways depending on its type and style. Board and batten siding is usually installed vertically with boards overlapping each other horizontally every few inches or so. Lap siding has no vertical seams but instead overlaps horizontally similar to shingles on a roof (except the laps are not visible).

Doors and Windows

As you prepare to build a 12×20 shed, it’s important to consider the quality and durability of your doors and windows. You don’t want to spend more time than necessary getting them installed, so choose wisely.

We recommend looking for doors and windows made of high-quality materials that have a good warranty attached to them. They also need to be backed by an established company with a reputation for quality products.

It’s better if you can install these yourself or find someone who can help you out with the project.

Building Trim

  • Trim, or decorative molding is the finishing touches of a house. It can be made from a variety of materials including wood, metal, and stone. You may also find trim available in different colors and styles to match your home’s décor.
  • Trim can be used for both interior and exterior applications. It’s often used to cover up imperfections in walls and ceilings.

Paint and Supplies

You will need to buy paint and supplies. Once you have your materials, you can do the work yourself or hire a contractor who will be able to help you with the painting process. It’s important to know that paint is not included in our list of materials; therefore, it should be included in your budget when calculating how much building a shed will cost. If you’re going to hire someone else, consider getting quotes from several contractors first so that you can compare prices and find one that fits within your budget range. Be sure that any contractor that comes over has been approved by your insurance provider, And remember: good quality paint is worth investing in because it lasts longer than cheap brands (and makes everything look prettier too).

Building a 12×20 shed is not as complicated as you might think.

Building a 12×20 shed is not as complicated as you might think.

The materials list and cost of materials will vary depending on where you live, but the following general outline should help you get started:

  • 2x4x8 treated lumber (posts): $3 per board foot ($3,600 total)
  • 1/2″ plywood (siding and flooring): $10 per sheet ($100 total)
  • 1/2″ T&G plywood for roof: $125 for two sheets ($250 total)

The cost to build a 12×20 shed will vary depending on the location, but in general, it should be between $5,000 and $7,000. This would include all materials needed and labor costs as well. The average cost is about $6,500 which includes all materials needed plus labor costs for one person working full-time for three weeks straight on this project.
