We’ve built decks on every kind of terrain imaginable. With years of expertise in Austin deck installation, the floating deck is one of the most flexible and cost-effective solutions we often recommend.
In this guide, we’ll explain what they are, how they differ from traditional decks, and why many homeowners trust deck builders Austin homeowners rely on—like us—for innovative backyard solutions.
Key Takeaways
- Floating decks are freestanding structures on concrete pier blocks, not deep foundations.
- They’re easier to install and move, ideal for DIYers or sites with uneven terrain.
- Materials are typically pressure-treated lumber and composite decking.
- Great for modern, low-profile aesthetics and versatile backyard layouts.
- Always check local building codes before building.
- Floating decks have a limited weight capacity, making them unsuitable for heavy items like hot tubs or large grills, unlike traditional decks, which support heavier loads due to their stable attachment to the house.
What Exactly Is a Floating Deck?
A floating deck is a ground-level deck that sits directly on concrete blocks or pier pads, not anchored to your home or embedded into the ground. This makes them easier and faster to build, perfect for weekend warriors or homeowners looking for a sleek, modern touch without needing major excavation.
A paver base can provide additional stability and aid in drainage, ensuring the structure remains. secure and moisture is kept at bay.
Unlike traditional decks requiring footings and framing deep in the soil, a floating deck “floats” just above ground level, supported by a series of piers or deck blocks. The result? A flexible, semi-portable structure that looks fantastic and is easier on the budget.
Floating Deck vs. Traditional Deck: Key Differences
The most obvious difference between a floating deck and a traditional one is foundation depth and permanence. Traditional decks are permanent fixtures, usually attached to your house and built on deep-set posts or concrete footings. Floating decks, on the other hand, are:
- Freestanding
- Built close to ground level
- Installed without digging deep footings
- Easier to move or adjust over time
If you want to expand your home’s footprint permanently, a traditional deck may be a better choice. But floating decks are hard to beat if you want something flexible, fast, and budget-friendly.
Why Homeowners Love Floating Decks
Floating decks have surged in popularity for good reason. Here’s why so many homeowners across Austin are choosing them:
- Easy installation: No need for permits in many cases (though we always recommend checking local codes).
- Great for uneven terrain: No major excavation needed.
- Modern aesthetic: Low profile = high style.
- Budget-conscious: Fewer materials and no excavation reduce costs.
As professional deck builders in Austin, we love the creative flexibility that floating decks offer. They’re ideal for hosting, lounging, dining, sitting, or just soaking up the Central Texas sunshine.
Floating Decks for Small Spaces and Urban Yards
A floating deck can be the perfect solution if you’re working with a compact backyard, side yard, or even a tight city lot. Their low profile and freestanding design make them easy to fit into narrow or irregular spaces without disrupting existing landscaping. Floating decks are typically smaller, making them ideal for compact spaces.
Here’s why they’re ideal for smaller areas:
- No heavy equipment required: No need to tear up your yard to pour footings or dig deep posts.
- Custom shapes and sizes: Easily adapt to tight corners, slopes, or odd layouts.
- Creates usable square footage: Instantly transforms underutilized areas into lounge zones, grill stations, or garden seating.
- Easy to remove or relocate: If your layout changes, your deck can too.
We’ve helped many Austin homeowners turn tiny backyards into cozy outdoor escapes with floating decks. Just because your small space doesn’t mean outdoor living can’t be big on impact.
What to Know Before Building One
Before you start laying boards, there are some critical things to consider:
It is essential to obtain the necessary permits before starting construction. Check with local authorities to confirm whether permits are required to ensure building code compliance and avoid legal issues.
Location and Layout
Pick a relatively flat location with good drainage and the right amount of sun/shade. Avoid low spots where water collects. Ensure proper support and weight distribution, especially in the middle of the deck, to prevent structural issues.
Materials You’ll Need
To build a floating deck, you’ll typically need:
- Concrete pier blocks or deck blocks
- Pressure-treated lumber for the frame
- Composite or natural wood decking boards
- Galvanized fasteners and joist hangers
- Gravel or landscape fabric for ground leveling (optional but helpful)
Tools
- Circular saw
- Power drill
- Impact driver: An impact driver is a powerful tool specifically designed for driving screws and bolts into various materials efficiently, incredibly dense materials.
- Tape measure
- Carpenter’s square

Know Your Local Building Codes

How to Build a Floating Deck (Step-by-Step)
Here’s a general breakdown of how we build floating decks for our clients:
- Plan and measure the space.
- Level the ground and lay down gravel or landscape fabric to reduce weed growth. Using landscape fabric can help prevent weeds from growing under the deck by acting as a barrier, which should be secured with staples and covered with gravel to ensure it stays in place.
- Place your pier blocks, making sure they’re evenly spaced and level.
- Build your frame using pressure-treated lumber.
- Attach joists and secure with galvanized fasteners.
- Install decking boards using hidden fasteners or deck screws.
- Add skirting or trim, if desired, for a clean look.
- Furnish and decorate—then relax and enjoy!
