Step By Step Instructions For Building Box Steps For Deck Construction

  • Measure and mark the area where the box steps will be built. Consider both the desired size of the steps and their location within the deck space, making sure they do not obstruct any other primary elements such as railings or stairs.
  • Use a circular saw to cut two pressure-treated 2×6 boards to the length of each step. The width of the boards will depend on how wide you want the box steps to be, but should generally be no less than 10 inches for stability.
  • Attach the two pressure-treated 2×6 boards at one end using 3″ decking screws and a cordless drill or impact driver. Make sure the boards are flush and level with each other.
  • Cut pressure-treated 2×4 boards to create the vertical risers that will hold up the box steps. The length of these boards should be the same as their corresponding step, but the width can vary depending on your desired design.
  • Attach the pressure-treated 2×4 boards to the step boards with decking screws, making sure they are flush and level.
  • Cut pressure-treated lumber to create the ceiling frame that will house the box steps, using a circular saw or miter saw. The length of each piece should be equal to the overall width of the box steps, plus the thickness of the risers.
  • Attach the ceiling frame to the risers using decking screws and a cordless drill or impact driver. Make sure that all pieces are flush and level with each other.
  • Attach two pressure-treated 4x4s to the bottom of the box steps, creating a support frame for the box steps. The length of these 4x4s should be equal to the overall width of the box steps.
  • Cut pressure-treated 2×6 boards to fit the ceiling frame and attach them with decking screws and a cordless drill or impact driver.
  • Cut pressure-treated 1×4 boards to create the skirting board, which will be attached to the outside-of-the-box steps. The length of these boards should be equal to the overall width of the box steps, plus 4 inches for overhang.
  • Attach the skirting board to the box steps with decking screws, making sure that all pieces are flush and level.
  • Finish your box steps by staining or sealing them with a suitable exterior wood finish product. This will help protect your box steps from weather damage and make them look great!

Follow these steps to build the perfect set of box steps for your deck construction project! With a little bit of planning and some basic tools, you can create beautiful and functional steps that will last you years to come.

Tips for ensuring proper support and stability

  1. Use pressure-treated lumber for all pieces that will make contact with the ground or concrete. This will help reduce warping and rotting over time.
  2. Make sure to use adequate fasteners when constructing your box steps – 3” decking screws are typically recommended.
  3. Construct a support frame underneath your box steps to ensure proper stability.
  4. Consider adding angled braces at the base of your box steps to further increase their strength and stability.
  5. When it comes to installation, make sure the box steps are level and square with the ground.
  6. If you’re going to be painting your box steps, use a waterproof paint or sealant to protect against moisture damage.
