Before we get into building a storage shed under your deck, let’s first understand why it’s a good idea. A storage shed has many advantages, such as:

  1. Maximizing Space:  Using the area under your deck allows you to make more storage space without using up valuable yard space.
  2. Easy Access:  Having a storage shed under your deck gives you easy and convenient access to your things. You won’t have to search through cluttered garages or basements anymore!
  3. Cost-Effective: Building a storage shed under your deck is a cheaper option than building a separate shed or renting storage space.
  4. Protection from the Elements:  Storing your items under the deck gives them some protection from harsh weather and keeps them safe from rain, snow, and too much sun.

Now that we understand the advantages, let’s talk about how to build a storage shed under your deck.


How To Build A Storage Shed Under Your Deck

Step 1: Deck’s Inspection

Before starting any project, check the condition of your deck. Safety should always be your main concern. If you’re not sure if your deck is strong enough, get a professional to inspect it.

It’s best to fix any necessary repairs or reinforcements with the deck before you build the storage shed.


Step 2: Storage Organisation

To build a storage shed that will serve you well, you need to know what you’re storing. Think about what you want to put in there, like gardening tools, outdoor furniture, or seasonal decorations. Knowing what you need to store will help you design a shed that fits your things perfectly.


Step 3: Choose the Right Storage Method

There are different ways to build a storage shed under your deck, depending on how much space you have, your budget, and what you want to use it for. Let’s look at two common options:

Option 1: Drawers for Easy Access

If your deck doesn’t have much space underneath, building drawers can be a great idea. It’s simple and doesn’t cost much. You can make a frame and attach drawers under the deck to store things. This is good for small items like garden tools, toys, and outdoor stuff.

Option 2: Hinged Skirting for Accessibility

If your deck has more space underneath, you can build hinged skirting. This means making a cubby hole under the deck that you can get to from outside by opening part of the skirting. You can use hinged panels or a section that you can take out. This gives you more storage space and makes it easier to get to bigger items like lawnmowers, bikes, or even a small outdoor furniture set.

Step 4: Waterproofing Considerations

Before you start building your storage shed, you might want to consider waterproofing. Your deck might already be waterproof depending on what it’s made of. But if it’s not, you’ll need to protect what you are storing from water.

If you’re storing things like plastic toys or garden hoses that can handle some moisture, you might not need to do anything extra. But if you’re storing things that need to stay dry, think about adding a waterproof barrier under the deck to keep water out.


Step 5: Materials and Construction

Now that you have a clear plan in mind, it’s time to gather the necessary materials and begin construction. Here’s a breakdown of the materials you may need:

  • Geotextile fabric for the storage area floor
  • Crushed stone for the storage area floor
  • Lattice or siding material for enclosing the storage area
  • Lumber for framing and supporting the enclosure
  • Fasteners, hinges, and latches for assembly
  • Concrete blocks (if necessary) for additional support


Follow these steps to construct your storage shed:

  1. Get the space under your deck ready by grading it so that it slopes away from the house. This helps with drainage and keeps water from pooling under the deck.
  2. To prevent weed growth and create a stable base, lay down geotextile fabric under the deck. This fabric helps to keep weeds from growing and provides a solid foundation for your storage shed.
  3. To create a durable and well-drained floor, spread a layer of crushed stone over the geotextile fabric. This helps to provide a stable base for your storage shed and allows for proper drainage.
  4. Use lumber to build a frame that will support the lattice or siding material.
  5. Follow the manufacturer’s instructions to install the lattice or siding.
  6. Make a strong door using lumber and hinges.
  7. Attach the door to the frame to make sure it closes securely.
  8. Finish the project by caulking and painting the enclosure. This adds protection and makes it look better.


Step 6: Organize and Personalize Your Storage Shed

After finishing your storage shed, organize your things and make the space your own. You can add shelves, hooks, or pegboards to fit more things. Label boxes or use clear containers so you can see what’s inside easily.

Adding light and ventilation can also make your storage shed more useful and comfortable. This is your space, so be creative with how you design and organize it. Make it match your style and storage needs.
