Planning Your Ground Level Deck Design

Building your own DIY ground deck begins with careful planning and thoughtful design. At Olympic Decks, we’ve perfected our approach through years of building perfect outdoor spaces, and we’re excited to guide you through the initial steps.

1. Visualize Your Deck’s Purpose. Start by envisioning the activities you’ll enjoy on your new deck. Whether it’s hosting vibrant summer barbecues, enjoying quiet afternoons with a book, or gathering friends for a stargazing night, each scenario might influence the size and layout of the deck.
2. Assess Your Yard’s Terrain. Your yard’s physical characteristics play a significant role in where your deck should be placed. Look for a flat area to minimize extensive ground leveling. If no flat area is available, consider whether you need to incorporate steps or tiered sections into simple deck ideas.
3. Sunlight and Shade. Consider how the patterns of sunlight and shade throughout the day will affect your comfort and the usability of the deck. You might want to position the deck where it can receive morning sunlight but is shaded during the hottest part of the afternoon.
4. Drainage Below the Deck. Proper drainage is critical to prevent water from pooling underneath, which can lead to wood rot and a shorter lifespan for your deck. Assess the natural slope of your yard for water run-off. The ideal setup allows water to drain away from both the deck and your house.
5. Enhance Drainage in Needed. To further enhance drainage, consider designing your deck with a slight slope away from your home. A gradient of about 1 to 2 degrees is subtle but effective in promoting water runoff, ensuring that moisture does not accumulate under your deck.
6. Ventilation Considerations. To prevent moisture buildup, ensure adequate ventilation beneath your deck. This can be achieved by leaving sufficient gaps between the decking boards and ensuring that the sides of the deck allow air to circulate freely.

By thoroughly planning your ground level deck and addressing these key considerations, you set the foundation for a successful build.

Materials Needed for Ground Level Deck Construction

Building a DIY ground deck requires a careful selection of materials and tools to ensure the structure is durable, aesthetically pleasing, and able to withstand the elements. Here at Olympic Decks, we recommend using specific types of materials that are best suited for the moist and variable Seattle climate. Below, you’ll find a detailed list of essential materials and tools, along with recommendations for choosing the most weather-resistant options.

• Framing Material: Since part of your deck’s structure may be close to or on the ground, opting for pressure-treated lumber is crucial. This wood is specially treated with preservatives that protect it against rot, decay, and insect infestation, making it ideal for ground contact applications. For the framing, ensure the lumber is rated for ground contact.
• Decking Material: You have a choice between traditional wood and composite materials. While wood is a classic choice, composite decking might be preferable due to its durability and low maintenance requirements. Composite materials are resistant to mold, warping, and fading, which are important considerations in the damp Pacific Northwest.
• Fasteners and Hardware: Use galvanized or stainless steel fasteners and hardware to prevent corrosion. These materials are designed to resist the deteriorating effects of outdoor exposure, particularly in wet conditions.

Don’t forget the tools for ground level deck construction:

• Measuring Tape and Level: Precision is key in deck construction, so a reliable measuring tape and a level are essential to ensure your deck is perfectly dimensioned and level.
• Circular Saw: A sturdy circular saw is necessary for cutting lumber or composite materials to the right dimensions.
• Drill and Drill Bits: A high-quality drill, along with various sizes of drill bits, will be required for making pilot holes and driving screws.
• Hammer or Nail Gun: Depending on your preference and the materials used, a hammer or a nail gun will be needed to assemble the deck components.

By selecting the right materials and tools for your DIY ground deck, you ensure not only a smoother construction process but also a long-lasting, durable outdoor living space that will host countless memories.

How to Build a Ground Level Deck: Step-by-Step Instructions

Building a low deck can transform your outdoor space into a beautiful and functional area perfect for many different outdoor activities. A  well-built deck needs to be done right, so we’ve put together comprehensive step-by-step instructions to guide you through the process from start to finish.

Step 1: Site Preparation

• Clearing the Area: Begin by clearing the deck area of any vegetation, rocks, and debris. This includes removing grass and, if necessary, any existing structures or paving.
• Leveling the Ground: Use a shovel and rake to level the ground. For areas with significant slopes, you may need to excavate or add soil to create a flat surface. Compact the soil to prevent settling, and use a long level or a laser level to ensure the area is even.

Step 2: Framing the Deck

• Marking the Layout: Use stakes and string to outline your deck’s footprint. Measure diagonally between opposite corners to check for squareness; adjust if necessary until both diagonal measurements are equal.
• Installing the Joists: Place pressure-treated beams directly on the ground, running perpendicular to the final deck board direction. Ensure each beam is level and properly supported along its entire length. Secure the joists to the beams using galvanized screws or joist hangers.
• Adding Blocking: Where necessary, add blocking between joists to increase stability and prevent the joists from twisting.

Step 3: Installing the Decking

• Choosing Boards: Select decking boards that are straight and free of significant knots. If using wood, pre-treat the cut ends with a wood preservative to extend their life.
• Laying the Boards: Start laying your decking boards from one edge of the deck, working towards the other. Ensure each board is aligned and straight as you progress.
• Spacing the Boards: Use spacers to maintain consistent gaps between the decking boards for drainage and expansion. Typically, a gap of about 1/8 inch is advisable.
• Securing the Boards: Fasten the decking boards to the joists using decking screws. For a cleaner look, consider using hidden fasteners or screws that can be countersunk and filled.

Step 4: Finishing Touches

• Adding Edging: Install a border around the edge of your deck to create a neat finish and hide the ends of the deck boards. This can be made from the same material as the decking or a contrasting material.
• Installing Skirting: Skirt your deck to cover the structure underneath and prevent animals from nesting under it. Skirting can be made from lattice, vertical boards, or other decorative elements that match the decking.
• Sealing and Staining: If your deck is wood, apply a sealant or stain to protect it from the elements and enhance its color. Even composite decks can benefit from a clean and occasional mildew-preventative treatment.

By following these detailed steps, you can build a ground level deck that will impress your friends and be robust and long-lasting. If any step is outside your comfort zone, don’t hesitate to call in professionals like us at Olympic Decks for assistance.
