A floating deck can transform your outdoor space into a relaxing retreat, perfect for entertaining or unwinding after a long day. You can place them anywhere in your yard, whether you envision a cozy nook under a shade tree or a sunny lounging spot. In this guide, we’ll explore nine stunning design ideas to inspire your backyard oasis.
What Is a Floating Deck?
A floating deck is a freestanding platform that sits just above the ground without attaching to a house or other structure. Unlike traditional decks, floating decks don’t need deep footings or complex support systems. Instead, they rest on concrete deck blocks or posts.
Planning Your Floating Deck Project
Before diving into construction, plan carefully to make sure your floating deck meets your needs and complies with local regulations.
Choosing the Perfect Location
When selecting the right spot for your floating deck, consider factors such as:
- Existing trees or features you want to incorporate
- Privacy
- Proximity to your home
- Sun exposure
- Views of your landscape
Determining Size and Shape
Your floating deck’s size and shape should complement your yard and suit your intended use. Consider how many people you want to accommodate and what activities you plan to enjoy on the deck. Rectangular designs are common, but don’t be afraid to explore curved edges or multilevel options for added visual interest.
Considering Local Building Codes
While floating decks often don’t require permits, we still recommend checking your local building codes before starting construction. Some areas may have restrictions on size, height, or proximity to property lines. Keeping within compliance will save you headaches down the road.
Choosing an Ideal Decking Material
The most common materials for a floating deck are pressure-treated wood and composite decking. Pressure-treated wood is affordable and resistant to insects and rot. Composite decking, though more expensive, offers excellent durability, low maintenance, and a variety of colors and textures. Other options include cedar and redwood. They’re popular for their natural beauty and resistance to decay but require more upkeep.
Guide to Building a Floating Deck
Depending on the size and shape, a floating deck requires basic building skills like how to use a drill and a level. If your lumber requires cutting, you’ll need to know how to use a saw as well. Here’s a simplified overview of the process:
- Gather materials: For the deck itself, you’ll need decking boards, concrete deck blocks or post anchors, and pressure-treated lumber for the frame and joists. You’ll also want gravel and landscape fabric for ground preparation. Have galvanized deck screws and nails, joist hangers, corner brackets, a level, measuring tape, and other basic tools on hand.
- Prepare the ground: Mark out the deck area with stakes and string. Remove the grass and topsoil to create a level surface, then add a layer of gravel and compact it for stability. Lay landscape fabric to prevent weed growth.
- Install deck blocks: Place concrete deck blocks at regular intervals according to your plan. Use a level to ensure all blocks are even.
- Construct the frame: Build a rectangular frame using pressure-treated 2-by-8 or 2-by-10 lumber. Install floor joists at 16-inch intervals for added support, and secure the frame with joist hangers and corner brackets.
- Lay the decking boards: Start at one edge of the frame and work your way across, leaving a small gap between boards for drainage and expansion. Secure the boards with deck screws, making sure they’re flush and aligned.

Safety Considerations
Safety is paramount in any DIY project. Wear personal protective equipment, such as gloves and eye protection. Ensure tools are in good working condition and use them as directed. We recommend keeping a first-aid kit nearby while working. When building structures higher off the ground, consider adding railings, especially if children or pets will use the deck.
Creative Floating Deck Designs
Now that you understand the basics, let’s explore some inspiring floating deck designs to elevate your outdoor space.
1. Floating Deck With Pergola
Adding a pergola to your floating deck creates a stunning focal point and provides shade for comfortable outdoor living. The vertical structure offers opportunities for hanging string lights, plants, or even a canvas cover for added sun protection. This combination of horizontal and vertical elements adds depth and interest to your backyard design.

2. Skirted Floating Deck
For a polished look that keeps critters at bay, consider adding skirting to your floating deck. This involves attaching trim boards around the deck’s perimeter to conceal the space underneath. Skirting enhances the deck’s appearance and helps protect the understructure from the elements.
You can build a 10-by-12-foot skirted floating deck in just one weekend.
3. Multilevel Floating Deck
If your yard has varying elevations, a multilevel floating deck can be an excellent solution. This design incorporates different platform heights to create distinct areas for dining, lounging, and entertaining. The steps between deck levels add visual interest and can help you navigate sloped terrain gracefully.
4. Floating Deck With Built-In Planters
Built-in planters can bring greenery directly onto your deck. These planters can be part of the deck’s structure, holding flowers, shrubs, or even small trees. We like this approach for gardens in urban areas with limited space.
5. Outdoor Kitchen Floating Deck
Take your outdoor entertainment to the next level by integrating kitchen features into your floating deck. Consider adding a grill, countertops, and storage for an outdoor cooking area. Hidden propane tanks fuel your grill and griddle while buried electric lines power a mini-fridge and lighting. Add a few drawers and a cabinet for utensils, dishes, and drinkware, and you can relax with friends and family rather than spend your time walking back and forth to your indoor kitchen.
6. Minimalist Floating Deck
For those who prefer a clean, modern look, a minimalist floating deck may be the perfect choice. This design uses sleek lines, simple shapes, and often a monochromatic color palette. The focus is on functionality and aesthetics, creating a serene and uncluttered outdoor space. Add subtle lighting and contemporary furniture to complete the look.
7. Floating Deck With a Fire Pit
A fire pit can transform your floating deck into an all-season gathering place. Choose a safe and deck-friendly model, such as a propane fire pit, to give warmth and ambiance without worrying about sparks. Portable models offer flexibility, or you can custom-design a built-in to fit your deck’s style.
8. Floating Deck With Privacy Screens
If your deck is visible to neighbors or passersby, privacy screens create a more intimate setting. Options range from premade lattice panels to custom-built wooden screens. You can even incorporate climbing plants for a natural privacy solution.
9. Floating Deck With Built-In Seating
Built-in benches or seating areas can maximize space on your floating deck while providing a cohesive look. These can be constructed along the edges of the deck, freeing up the center for tables or other furniture. Add cushions and pillows for comfort and a pop of color.
Enhancing Your Floating Deck With Lighting
Extend the usability of your floating deck into the evening hours with strategic lighting. Consider these options:
- Lanterns or candles for ambiance
- Recessed LED deck lights
- Solar-powered deck post caps
- String lights hung overhead
Cost Comparison: Floating Deck vs. Attached Deck vs. Paver Patio
When considering outdoor living spaces, many homeowners debate between a floating deck and a paver patio. While costs and benefits can vary depending on material and size, here’s a general comparison of the three styles:
| Type | Price per Square Foot* | Pros | Cons |
|---|---|---|---|
| Floating deck | $20–$60 | • Lower cost and easier to build • Flexible placement options | • Shorter lifespan • Requires more frequent maintenance |
| Attached deck | $30–$60 | • More stable than a floating deck • Increased home value | • Typically requires a permit • Expensive |
| Paver patio | $6–$30 | • Long lifespan • Low-maintenance once installed | • Difficult to build on uneven ground • Less improvement to home value |
