Building a ground level deck can transform your backyard into a functional outdoor space. It provides an excellent area for extra seating, entertainment, and relaxation. Even tackling this project as a beginner can be manageable with proper planning and simple tools.

Choosing the right materials is crucial. Wood, composite, and vinyl are popular options, each offering different benefits. Make sure to select durable materials that will withstand weather conditions.

A well-constructed ground level deck enhances the aesthetic value of your home. By following step-by-step instructions, homeowners can enjoy a beautiful deck that adds charm to their outdoor area without professional help.

Designing Your Deck

Designing a ground-level deck involves choosing the right materials, determining the size and shape, and planning for sun and shade. Each step will impact the functionality and look of your deck.

Choosing the Right Materials

Wood is a popular choice for decking. It’s natural and looks great, but it needs regular maintenance like staining and sealing to prevent rot and insects. Composite materials, made from wood fibers and plastic, are another option; they’re low-maintenance and long-lasting. PVC decking is also low-maintenance and resistant to moisture and insects, but it can be more expensive.

When choosing materials, consider climate and foot traffic. High-traffic areas might benefit from more durable materials. For a cohesive look, match the decking material to other elements in your yard, such as fencing or garden structures.

Determining the Size and Shape

The size and shape of your deck depend on how you plan to use it. For outdoor dining, a larger deck may be necessary to fit a table and chairs. If you want a cozy seating area, a smaller, more intimate space might be better. Measuring the available space and considering furniture layout is essential.

Think about the flow between indoor and outdoor spaces. A deck that connects smoothly to the house can enhance usability. Avoid complex shapes if you’re a beginner; rectangular or square decks are easier to build and furnish.

Planning for Sun and Shade

Sun and shade play a big role in how enjoyable your deck will be. Take note of the sun’s position at different times of the day. Pergolas or retractable awnings can provide adjustable shade. Umbrellas or shade sails are also easy options for creating shaded areas.

If the deck gets too much sun, consider building in some shade structures or planting trees nearby. For decks mostly in the shade, make sure the material you choose can handle moisture well to avoid issues with mold and mildew.

By taking the time to plan these aspects, you can create a deck that suits your needs and lasts for years.

Preparing the Build Site

Building a ground level deck starts with getting the site ready. This involves clearing the area and making sure it is level, then measuring and staking out the layout for accuracy.

Clearing and Leveling the Area

Start by removing any grass, weeds, or debris from the area. Use a shovel and a rake to clear everything out. If there are any rocks or roots, dig them up and move them out of the way.

Next, check the ground to see if it is level. A long board and a carpenter’s level can help with this. Place the board on the ground, then set the level on top. Adjust the ground by adding or removing soil until it’s even.

In areas with a significant slope, consider renting a plate compactor to flatten the soil. This helps provide a stable base for your deck and prevents future issues. A smooth, level base is critical for structural stability.

Measuring and Staking the Layout

First, measure the dimensions of your deck. Use a tape measure to mark the length and width on the ground. Ensure you get precise measurements to avoid mistakes during the construction.

Drive wooden stakes into the ground at each corner of the marked area. Use string to connect these stakes, forming the outline of your deck. This helps visualize the space and keeps your measurements intact.

Double-check each corner to confirm the layout is square. Use a carpenter’s square or measure the diagonals; they should be equal. Keeping the layout square ensures your deck has equal and balanced sides, which is crucial for construction.

Mark any specific areas where posts or supports will go. This can help avoid later adjustments and makes the building process smoother.

Building the Foundation

Building the foundation of a ground-level deck is crucial. It involves selecting the right footings and setting posts correctly to ensure stability and longevity.

Selecting and Installing Footings

The first step is to choose the proper footings. Footings are essential as they provide the deck with a stable base. Concrete footings are commonly used due to their strength and durability. They should be placed at least 12 inches below the ground to avoid shifting caused by frost. The number of footings depends on the size of the deck. It is crucial to measure and mark the spots accurately using a tape measure and stakes.

After marking, dig holes for the footings. The diameter should be at least three times the width of the posts. Pour concrete into the holes, making sure it is level and smooth. Allow the concrete to cure for a minimum of 24 hours before proceeding to the next step.

Setting the Posts

After the footings are cured, he or she can begin setting the posts. Begin by cutting the posts to the desired height. It is important to double-check measurements to ensure a level deck. Posts should be treated lumber to resist decay and insects.

Attach post anchors to the footings to provide a solid connection. Then, place the posts onto the anchors and secure them with carriage bolts. Use a level to ensure each post is perfectly vertical.

Spacing between posts should not exceed 8 feet to maintain structural integrity. Once all posts are set, he or she can proceed with framing the deck.

Constructing the Frame

Constructing the frame involves setting up the ledger, joists, and beams, and making sure the structure is stable and level.

Assembling the Ledger, Joists, and Beams

The ledger board gets attached to the house first. It should be level and securely fastened into the wall studs. Use lag bolts for a firm hold. Ensure it’s treated lumber to resist rot.

Next, install the post bases in the ground at the corners for the beams. Posts should be pressure-treated and concreted in place. This gives a strong base to support the weight of the deck.

Then, install the joists between the ledger and the beam. Space them evenly, usually 16 inches apart, using joist hangers to hold them in place. Ensure they are all level.

Ensuring Structural Integrity

To keep the deck sturdy, use cross bracing between the posts. This prevents swaying. Angle braces should be added at the corners for extra support.

Double-check all connections and fasteners. Make sure they are tight and secure. Nails, screws, and bolts should be galvanized or stainless steel to prevent rust.

Finally, ensure the entire frame is level and square. Use a carpenter’s level and measuring tape. Any errors here can cause problems later when laying the decking boards. Correct any misalignments immediately.

Installing the Decking

Installing decking involves laying deck boards evenly and securely fastening them to ensure the deck is safe and durable.

Laying the Deck Boards

Start by deciding on the direction the deck boards will run. Typically, boards run perpendicular to the joists for stability.

Place the first board along the edge you chose. Ensure it is straight and aligned with the frame. Secure it temporarily with a few screws.

Leave a small gap between each board to allow for expansion and water drainage. A gap of about 1/8 inch is usually recommended.

Continue placing the boards across the deck. Use a spacer to maintain consistent gaps. Trim the ends of the boards as needed to fit within the deck frame.

Double-check the alignment as you go to ensure a uniform look. Adjust boards if necessary to correct any misalignments.

Fastening Techniques

Fastening the deck boards properly is crucial. Screws are commonly used because they provide a strong hold and are easier to remove for future repairs.

Start by pre-drilling holes at each joist intersection before inserting screws. This prevents the wood from splitting.

Countersink the screws slightly below the surface of the board. This gives a clean look and prevents tripping hazards.

Use two screws per joist intersection for a secure connection. Position screws about 3/4 inch from the edges of the board.

Alternatively, hidden fasteners can be used. These clips attach to the sides of the boards and fit into grooves cut into the wood, providing a smooth surface with no visible screws.

Keep the fasteners evenly spaced and in alignment to maintain the deck’s integrity and appearance.

Finishing Touches

To complete your ground level deck, consider applying stain or sealant for durability and adding functional elements like railings and stairs.

Applying Stain or Sealant

Stains and sealants protect the wood from weather, insects, and wear. They also enhance the wood’s appearance.

  • Preparation: Sand the surface lightly to ensure the stain or sealant adheres well. Clean thoroughly to remove dust and debris.
  • Application: Use a roller or brush for even coverage. Apply the stain or sealant in thin, even coats. Allow each coat to dry completely before adding another.
  • Maintenance: Reapply every few years to maintain protection. Regularly inspect for areas that may need touch-ups.

Adding Railings and Stairs

Railings and stairs enhance safety and accessibility.

  • Materials: Choose materials that match or complement your deck. Common options include wood, metal, and composite.
  • Installation: Measure accurately for the height and width of the railings and stairs. Secure them with appropriate hardware, ensuring stability.
  • Safety: Ensure railings are sturdy and spaced properly to prevent accidents. Stairs should have uniform height and depth to avoid tripping.

By focusing on these details, your deck will be safe, attractive, and long-lasting.
