Floating decks have become a popular outdoor feature for homeowners who want to create a usable and attractive space without the hassle of permanent construction. As the name suggests, a floating deck “floats” above the ground, resting on concrete blocks or gravel without being anchored into the soil. But while they offer flexibility and convenience, floating decks also come with limitations. If you’re considering building one, it’s important to weigh both the pros and cons to decide if it’s the right choice for your space.
The Pros of a Floating Deck
- Simple Construction
One of the biggest advantages of a floating deck is that it’s relatively easy to build. Unlike traditional decks that require digging deep footings or attaching ledger boards to a house, floating decks can be installed directly on top of the ground. This makes them a great DIY project for homeowners with basic carpentry skills and the right tools.
- No Building Permit in Some Areas
Because floating decks are not considered permanent structures, many areas don’t require permits for decks under a certain height. This can save time and money during the planning and building process. However, always double-check local regulations before starting.
- Flexibility in Placement
Floating decks can be built almost anywhere in your yard—as long as the ground is relatively level. They don’t need to be connected to the house, so you can position them under a tree, beside a garden, or near a pool. This versatility allows for creative outdoor designs that fit your lifestyle.
- Cost-Effective
Since floating decks require fewer materials and no deep foundations, they often cost less to build than standard raised decks. You won’t need to hire specialized labor or rent heavy equipment, making them an affordable option for adding functional outdoor space.
- Easier Repairs and Adjustments
If a section becomes damaged or you want to reposition the deck in the future, floating decks are much easier to adjust or disassemble compared to permanent ones. This is especially helpful in areas with shifting soil or where future landscaping plans may change.
The Cons of a Floating Deck
- Less Stability
Because floating decks sit on the ground, they are more likely to shift slightly over time—especially in areas with freeze-thaw cycles or soft soil. Unlike anchored decks, they don’t have deep footings to hold them in place permanently. Regular leveling and maintenance may be needed.
- Limited Height
Floating decks are best suited for low-profile builds, typically less than 24 inches off the ground. If you’re planning a tall or multi-level deck, a floating design isn’t ideal. Going too high without proper support can make the structure unsafe and wobbly.
- Moisture Concerns
Since floating decks rest directly on or close to the ground, they are more exposed to moisture from rain and soil. This can lead to faster wood decay if not properly sealed or maintained. Adding gravel or a vapor barrier underneath can help reduce moisture buildup.
- Not Always Suitable for Uneven Terrain
While they can be placed almost anywhere, floating decks require relatively flat ground for safe installation. Steep slopes or uneven surfaces can complicate the build or make the deck unstable. You may need to level the site or use additional support blocks, adding to the labor and cost.
- May Affect Resale Value
Although floating decks are great for short-term use, potential homebuyers might view them as less valuable than a permanent structure. This may not matter to everyone, but it’s worth considering if you’re looking to boost property value.
Final Thoughts
Floating decks are a great option for adding beauty and function to your outdoor space—especially if you want something affordable, flexible, and relatively simple to build. However, they do have some trade-offs when it comes to durability and long-term stability. By understanding both the advantages and drawbacks, you can make an informed decision that fits your home, your yard, and your goals.
