This guide provides a step-by-step approach to building a small storage shed, using insights from a DIY shed-building project. By the end, you'll have the knowledge to tackle your own shed project.

Planning and Gathering Materials

Before you begin, the first step is planning the shed size and gathering materials. For this project, a 3x7.5-foot shed was chosen, a compact but functional size for many backyards. To reduce costs, consider reusing materials you already have on hand, as this project demonstrated how to build a shed for free using leftover materials. Here's what you'll need:

Materials List

Wood: Gather lumber such as 2x4s and plywood for framing, roofing, and siding. Any extra lumber lying around can be repurposed for the structure.
Roofing Material: Metal roofing panels or shingles can be sourced from leftover projects.
Concrete Blocks: These can serve as footings for the foundation.
Hardware: Nails, screws, L-brackets, and hurricane ties for securing framing and roof rafters.
Tyvek House Wrap: To protect the shed from moisture.
Flashing Tape and L Flashing: For waterproofing the base and roof edges.
Caulk and Paint: For finishing and protecting the exterior.
Door Hardware: A door lock and handle, or even a keypad entry system for added convenience.

Tools You'll Need

Hammer and Framing Nailer: For assembling the framing.
Tape Measure and Speed Square: To ensure accurate measurements and straight cuts.
Chop Saw or Circular Saw: For cutting lumber and siding.
Drill: To fasten screws and hardware.
Level and Laser Level: To ensure the shed is level during construction.

With your materials and tools ready, the next step is preparing the site and setting the foundation.

Step by Step Instructions

Build your own DIY small shed with step-by-step instructions, from foundation to finishing touches like caulking and painting. Perfect for any backyard.

1. Setting the Foundation

A sturdy foundation is essential for any shed, ensuring it remains level and stable over time. For this project, the shed was built on an unproductive space next to the house, utilizing concrete blocks for footings.

Clear and Level the Site

Begin by clearing the site of debris and vegetation. You want to expose the soil beneath. For this shed, the soil was tamped down using a hand tamper. Ideally, you would add crushed gravel to improve drainage, but this step can be skipped if you don't have gravel on hand.

Install Concrete Block Footings

Use concrete blocks as footings for the shed. These blocks serve as the foundation, elevating the structure and keeping it off the ground. The footings should be level, so use a laser level to ensure accuracy. If necessary, add or remove soil to adjust the height of the footings.

Modify Footings as Needed

In some cases, you might need to modify the concrete blocks to fit the shed's dimensions. For instance, some blocks may need to be trimmed or reshaped. This can be done using a multi-tool or handsaw.

2. Framing the Shed

With the foundation in place, it's time to move on to framing. The frame provides the structural support for the walls, roof, and door.

Building the Walls

Start by constructing the wall frames using 2x4s. For this shed, the front wall was designed to be taller than the back, building a lean-to roof. This allows for water runoff and adds height to one side of the shed, ideal for storage. Here's a step-by-step guide to building the wall frames:

Cut the 2x4s to the desired lengths for the walls.
Assemble the frames on the ground, ensuring they are square by checking the diagonal measurements. Use nails or screws to secure the joints.
Install the king and jack studs around the door opening to provide extra support for the header.
Once the frames are built, stand them up and secure them to the concrete footings and the side of your house using long lag screws.

Roof Framing

Next, frame the roof using 2x4s as rafters. In this project, 10-degree cuts were made at the ends of the rafters to accommodate the roof's slope. Secure the rafters to the walls using hurricane ties and L-brackets for added stability.

3. Adding the Roof and Siding

Learn about adding the roof and siding with our guide on roof and siding installation for durable and efficient home exteriors.

Install the Roof

Once the frame is complete, it's time to install the roof sheathing. Use plywood or other sheathing materials you have on hand. For this shed, a full sheet of plywood was cut down to size and used for the roof, with an overhang on all sides to protect the walls from rain.

After the sheathing is installed, apply Tyvek house wrap or another moisture barrier over the plywood. Then, fasten the roofing material to the sheathing. In this project, metal roofing panels left over from a previous shed build were used. Be sure to apply flashing around the roof edges to prevent leaks.

Siding Installation

The siding can be made from various materials, such as plywood, OSB, or even decking boards. In this build, leftover decking boards were cut at a 45-degree angle and used as siding. This innovative solution not only saved money but also provided a unique look for the shed.

Start at the bottom and work your way up, overlapping each row to build a watertight barrier. Secure the boards with galvanized nails to prevent rusting.

4. Door Installation

Now that the walls and roof are in place, it's time to install the door. For this project, a 36-inch door was chosen to maximize the shed's width.

Hang the Door

The door was installed to swing outward, maximizing the interior space. To install the door:

Shim the door in place to ensure it's level and plumb.
Secure the door frame to the shed with screws, making sure there are at least three connections on each side.
Add door trim around the edges to provide a clean finish and additional weatherproofing.

Install Door Hardware

For security, install a door lock or keypad entry system. In this project, a Brinks keypad lock was used for convenience, allowing access without needing a key.

5. Finishing Touches

With the shed structure complete, the final steps involve sealing, painting, and adding trim.

Caulk and Seal

Apply caulk to all joints and seams where water could enter. Pay special attention to the corners, around windows, and between siding boards. Use a high-quality exterior caulk designed for siding.

Paint the Shed

Once the caulk is dry, apply a coat of wood primer to all bare wood surfaces. After the primer dries, paint the shed in the desired color. Two coats of paint are recommended for long-lasting protection.

Add Trim

Add trim around the corners, roofline, and door to give the shed a finished look. This can be made from leftover wood cut to size. Ensure that all trim is securely fastened and painted.

Conclusion

Building a small DIY shed is a manageable project that can be done with minimal costs, especially if you repurpose materials you already have. This guide outlined the essential steps to constructing a small shed, from setting the foundation to installing the roof, siding, and door. By following these steps, you'll be well on your way to building a functional and attractive storage space for your backyard. With a little creativity and resourcefulness, you can build your shed without breaking the bank!
