A floating deck, also known as a freestanding deck, is a ground-level or near-ground-level deck that is not attached to a house or other structure. Unlike traditional decks that rely on ledger boards and direct connections to a building’s foundation, a floating deck stands independently, resting directly on the ground or a minimal support system.
Understanding the Fundamentals of Floating Decks
The key characteristic of a floating deck is its lack of attachment to a building. This independence offers several advantages and also some specific considerations during the design and construction phases. It’s not just a matter of slapping down some wood; it’s a well-thought-out structure.
The Concept of “Floating”
The term “floating” can be a bit misleading. It doesn’t mean the deck literally hovers in the air. Instead, it refers to the fact that the deck’s frame rests on a series of supports, typically concrete blocks, gravel, or specialized deck blocks, without being anchored to a foundation or building. This allows the deck to “float” independently, accommodating slight ground movement without impacting the structure it is near.
Key Differences from Traditional Decks
The most significant difference between a floating deck and a traditional deck lies in its connection to a building. Traditional decks are usually attached to the house via a ledger board, which is bolted to the building’s framing. This connection provides stability but also requires careful attention to waterproofing and structural integrity to prevent water damage and potential structural issues to the house. Floating decks bypass this connection entirely, eliminating the need for a ledger board and the associated concerns.
Advantages of Floating Decks
Floating decks offer numerous benefits:
- Ease of Construction: Because they don’t require attachment to a house, floating decks are generally easier and faster to build than traditional decks. This makes them a popular choice for DIY enthusiasts.
- Lower Cost: The reduced complexity of the construction process often translates to lower material and labor costs. The absence of the ledger board, specialized flashing, and related installation expenses contributes to the overall affordability.
- Versatility: Floating decks can be built in a variety of shapes and sizes, making them adaptable to different landscapes and design preferences. They can be placed in almost any outdoor setting, away from the house if desired.
- No Building Permits (Potentially): In some jurisdictions, building permits may not be required for floating decks, particularly those that are very low to the ground. However, always check your local building codes before starting any construction project. This is a crucial step.
- Reduced Risk of Damage to Existing Structure: Since they are not attached, floating decks pose no risk of water damage or structural problems to the existing house. This eliminates concerns about improper ledger board installation or inadequate flashing.
Disadvantages of Floating Decks
While floating decks have many advantages, they also have some drawbacks:
- Limited Height: Floating decks are typically limited to a low profile, as they rely on ground-level supports. They are not suitable for elevated deck designs.
- Ground Preparation: Proper ground preparation is essential for a stable and long-lasting floating deck. This may involve leveling the ground, adding gravel for drainage, and ensuring adequate support for the deck frame. Neglecting this can lead to settling and instability.
- Potential for Weed Growth: Weeds can grow up through the gaps between deck boards if proper weed control measures are not implemented. This requires ongoing maintenance.
- Perceived Instability: Some people may perceive a floating deck as less stable than a traditional deck, especially if it is not properly constructed. A well-built floating deck, however, can be just as sturdy.
Planning Your Floating Deck Project
Careful planning is crucial for a successful floating deck project. This involves considering the size and shape of the deck, the materials you will use, and the site preparation required. Don’t just wing it!
Deck Size and Shape
Determine the desired size and shape of your deck based on your available space and intended use. Consider the number of people you want to accommodate, the furniture you plan to place on the deck, and the overall aesthetic you want to achieve. Simple rectangular or square decks are the easiest to build, but more complex shapes can be created with careful planning and cutting.
Material Selection
Choosing the right materials is essential for the longevity and appearance of your floating deck. Common decking materials include:
- Pressure-Treated Lumber: This is a popular and affordable option for the deck frame and decking boards. It is treated to resist rot, decay, and insect infestation. However, it requires regular sealing or staining to maintain its appearance and prevent warping.
- Cedar: Cedar is a naturally durable wood that is resistant to rot and insects. It has a beautiful reddish-brown color and a pleasant aroma. Cedar is more expensive than pressure-treated lumber but requires less maintenance.
- Redwood: Redwood is another naturally durable wood that is resistant to rot and insects. It has a rich, reddish-brown color and a smooth texture. Redwood is similar in price to cedar and requires minimal maintenance.
- Composite Decking: Composite decking is made from a blend of wood fibers and plastic. It is highly durable, low-maintenance, and resistant to rot, decay, and insect infestation. Composite decking is more expensive than wood decking but offers long-term cost savings due to its reduced maintenance requirements.
- PVC Decking: PVC decking is made entirely of plastic. It is extremely durable, waterproof, and resistant to rot, decay, and insect infestation. PVC decking is the most expensive option but offers the highest level of durability and low maintenance.
Consider the pros and cons of each material before making a decision. Factors to consider include cost, durability, maintenance requirements, appearance, and environmental impact.
Site Preparation
Proper site preparation is critical for a stable and long-lasting floating deck. This involves:
- Clearing the Area: Remove any vegetation, debris, and topsoil from the area where the deck will be built.
- Leveling the Ground: Ensure the ground is level to provide a stable base for the deck. Use a shovel and level to remove any high spots and fill in any low spots.
- Adding Gravel: Add a layer of gravel to the area to improve drainage and prevent weed growth. A 4-6 inch layer of gravel is typically sufficient.
- Installing Weed Barrier Fabric: Lay down a layer of weed barrier fabric over the gravel to further prevent weed growth.
- Positioning Support Blocks: Place concrete blocks or deck blocks at regular intervals to support the deck frame. The spacing between blocks will depend on the size and thickness of the deck frame.
Careful site preparation will ensure that your floating deck is stable, level, and resistant to weed growth. Don’t skip this crucial step!

What exactly is a floating deck and how does it differ from a traditional deck?
A floating deck, also known as a freestanding deck, is a deck that is not attached to a house or other structure. It sits directly on the ground, supported by a framework of joists and beams that rest on concrete blocks or pavers. This differs significantly from a traditional deck, which is typically connected to the house and supported by posts that are set into the ground below the frost line.
The key distinction lies in the foundation and attachment method. Traditional decks require digging deep footings and attaching ledger boards to the house for support, making them a more permanent and complex construction project. Floating decks, on the other hand, are easier and quicker to build because they require minimal excavation and no direct attachment to the home. This makes them a great option for DIYers and those seeking a less invasive deck building solution.
What are the primary advantages of choosing a floating deck over a conventional deck?
One of the biggest advantages of a floating deck is its ease of construction. Because it doesn’t require attaching to the house or digging deep footings, the building process is significantly simpler and faster. This can translate to lower labor costs if you’re hiring someone, or a quicker DIY project if you’re tackling it yourself. They are also ideal for situations where attaching a deck to the house is not feasible or desirable, such as when dealing with specific siding types or rental properties.
Furthermore, floating decks offer greater flexibility in terms of location and design. They can be placed virtually anywhere in your yard, allowing you to create a deck space that perfectly suits your landscaping and outdoor needs. Their modular nature also makes them relatively easy to disassemble and move if your needs change or you decide to relocate.
What are the potential drawbacks or limitations of a floating deck?
Floating decks, due to their construction, tend to have a lower weight-bearing capacity compared to traditional decks anchored to a foundation. This might limit the number of people you can comfortably accommodate on the deck at one time, or restrict the placement of heavy items like hot tubs. Careful consideration of the deck’s intended use and weight distribution is crucial during the planning phase.
Another potential limitation is their proximity to the ground. Being close to the ground can make them more susceptible to moisture damage and insect infestation. Adequate drainage around the deck and the use of pressure-treated lumber or composite decking materials are essential to mitigate these risks and ensure the longevity of the structure.
What type of ground preparation is required before building a floating deck?
Proper ground preparation is vital for the stability and longevity of a floating deck. Begin by clearing the area of any vegetation, rocks, and debris. Leveling the ground is crucial to ensure the deck surface is even and stable. This can be achieved by removing or adding soil as needed, and using a level to verify the flatness of the surface.
After leveling, consider adding a layer of gravel or crushed stone to improve drainage and prevent weed growth. A weed barrier fabric should then be placed over the gravel to further inhibit weed growth and maintain the integrity of the base. Finally, compact the gravel or crushed stone using a hand tamper or plate compactor to create a firm and stable foundation for the concrete blocks or pavers that will support the deck frame.
What materials are typically used to build a floating deck?
The framing of a floating deck is typically constructed using pressure-treated lumber to resist rot and insect damage. The size and spacing of the joists and beams will depend on the size of the deck and the expected load. For the decking surface, options include pressure-treated lumber, composite decking, or even hardwoods like cedar or redwood. Composite decking is a popular choice due to its durability, low maintenance, and resistance to weathering.
The foundation of the deck relies on concrete blocks or pavers, which provide a stable and level base for the framing. These blocks or pavers are placed directly on the prepared ground. Other necessary materials include fasteners such as screws and nails (preferably stainless steel or coated for weather resistance), landscape fabric for weed control, and gravel or crushed stone for drainage.
Does a floating deck require a building permit?
Whether or not a building permit is required for a floating deck depends on local building codes and regulations. Many municipalities have specific rules regarding deck height, square footage, and proximity to property lines. Decks below a certain height, often 30 inches or less above ground level, may be exempt from permitting requirements.
It is essential to contact your local building department or zoning office before starting any construction project to determine the specific permitting requirements in your area. Failing to obtain the necessary permits can result in fines, delays, or even the requirement to remove the deck entirely.
How can I maintain a floating deck to ensure its longevity?
Regular cleaning is essential to maintain the appearance and longevity of a floating deck. Sweep the deck regularly to remove dirt, leaves, and other debris that can trap moisture and promote mold or mildew growth. Periodically wash the deck with a mild soap and water solution, using a scrub brush to remove any stubborn stains or grime.
Inspect the deck annually for signs of damage, such as loose screws, warped boards, or insect infestation. Replace any damaged boards or fasteners promptly to prevent further deterioration. If the deck is made of wood, consider applying a sealant or stain every few years to protect it from the elements and prevent fading or cracking. Also, ensure proper drainage around the deck to prevent water from pooling and causing rot.
