11 Step-by-step Guidelines on How to Build a Shed Under a Deck

Step 1: Clear Any Clutter or Debris

Before you begin your project, it’s important to make sure the area beneath your deck is free of any debris or clutter. This will help ensure that the shed you build will fit properly in the space. It’s also important to check for any critters who may have decided to make your decking their home, so be sure to look out for any signs of pests or animals before you start. This will save you a lot of trouble in the long run.

Step 2: Measure Your Deck Area

Using a measuring tape, measure the length and width of the area beneath your deck. This will help ensure that you purchase appropriate materials for building your shed – specifically ones that won’t be too large or too small for the space. It’s also important to measure any staircases or banisters near the area so that you don’t accidentally purchase materials that won’t fit.

Step 3: Determine What Type of Material You Want to Use

Depending on how much storage space you need and what kind of style fits with the aesthetics of your home, decide whether you’d prefer using wood, metal or vinyl to build your shed. This will help you decide what type of material to purchase and how much budget you’ll need for the project.

It’s important to remember that wood and metal are heavier than vinyl, so if you’re planning on attaching your shed directly to the deck, then it might be best to opt for vinyl as it’s lighter and easier to install.

Step 4: Choose an Appropriate Color Scheme for Your Shed

Most sheds come in a variety of different colors, so be sure to choose one that will complement the existing color scheme of your deck.

Once you’ve decided on which materials and colors to use, it’s time to order them online or from a local store. Make sure to double check measurements when ordering so there won’t be any surprises later on.
