How to Build a Platform Deck on the Ground

1. Planning and Design

Before you start building, take the time to plan and design your platform deck:

• Determine the Size and Location: Choose a flat area in your yard with proper drainage. Consider the size based on your needs and available space.

• Check Local Building Codes: In many areas, a ground-level deck may not require a permit, but it’s always best to check with local authorities.

• Choose Your Materials: Pressure-treated lumber is a cost-effective and durable choice. You can also use composite decking for a low-maintenance option.

2. Gather Your Materials and Tools

To build a platform deck, you’ll need the following materials and tools:

• Materials:

  • Pressure-treated lumber (for frame and decking boards)

  • Gravel (for drainage and base leveling)

  • Concrete deck blocks (to support the frame)

  • Galvanized screws and decking fasteners

  • Weed barrier fabric (to prevent grass and weeds)

• Tools:

  • Circular saw and drill

  • Level and measuring tape

  • Shovel and rake

  • Rubber mallet

3. Prepare the Site

Proper site preparation is essential for a stable and long-lasting deck:

• Clear the Area: Remove grass, rocks, and debris from the area where the deck will be installed.

• Level the Ground: Use a rake to level the soil, creating a flat surface.

• Add a Gravel Base: Spread a 2-3 inch layer of gravel to enhance drainage and prevent the deck from shifting.

• Lay Weed Barrier Fabric: Place weed barrier fabric over the gravel to prevent weed growth under the deck.

4. Build the Deck Frame

The frame is the foundation of your platform deck:

• Lay Out the Frame: Arrange pressure-treated lumber on top of the deck blocks to form the perimeter of the deck. Ensure it’s level and square.

• Secure the Joists: Attach the joists to the frame, spacing them 16 inches apart for support.

• Check for Level: Use a level to ensure the frame is even before securing it in place.

5. Install the Decking Boards

Once the frame is complete, it’s time to add the decking boards:

• Start from One Side: Begin installing the decking boards from one side of the deck, leaving a small gap between each board for drainage.

• Secure with Decking Screws: Use galvanized screws or decking fasteners to secure the boards to the frame.

• Trim the Edges: Once all boards are installed, trim the edges for a clean and uniform appearance.

6. Finishing Touches

• Sand and Seal: Sand any rough edges and apply a weather-resistant sealant to protect the wood from the elements.

• Add Railings (Optional): If desired, add railings for safety and style.

• Decorate and Enjoy: Furnish your new deck with outdoor furniture and accessories to create a cozy, inviting space.
