What Is a Floating Deck?
A floating deck is a freestanding wooden platform that rests directly on the ground without needing to be attached to a structure. Unlike traditional decks, it doesn’t require digging deep footings or pouring concrete, which makes floating deck construction much simpler and faster.
You’ll often see floating decking used to create cozy seating areas in backyards, patios, or garden spaces. Since you can build a floating deck without disturbing the land too much, it’s ideal for flat areas with good drainage. And because of San Diego’s mild climate, this style of deck holds up well year-round with minimal maintenance.
Before You Begin
Before learning how to build a floating deck, take a few simple but important planning steps to avoid costly mistakes. Start by checking local building codes or HOA rules; some areas may have specific limits on deck height or placement. Then choose a flat location with good sunlight, airflow, and natural drainage for your future floating patio.
Once your spot is picked, measure the area carefully and start sketching out your floating deck blueprints. Whether you’re going for a simple layout or following 12×12 floating deck plans, having a clear plan helps you build safely and smoothly. Based on 23 years of experience in San Diego remodeling, we always suggest marking underground utility lines before setting your floating decking frame; it’s a small step that can prevent big headaches later.
What You’ll Need
Before building your ground level deck, having the right tools and materials is the first step to a successful project. Whether you’re working from floating deck blueprints or designing your own small floating deck, it’s important to stay organized and ready. Below is a simple table listing everything you’ll need to get started.
Tools | Materials |
Measuring tape | Pressure-treated wood or composite decking |
Level | Deck blocks (for a stable base) |
Power drill | Joist hangers, screws |
Circular saw or handsaw | Landscape fabric and gravel (for drainage) |
Hammer | Waterproof wood sealant (optional but recommended) |
Safety gloves & goggles | Concrete pads (if not using deck blocks) |
To build a sturdy floating decking frame, make sure your wood is rated for ground contact. If you’re building a floating deck using deck blocks, choose eco-friendly options that offer long-term strength and weather resistance. For upgrades, consider adding steps, railings, or bench seating great additions to any small floating deck project. At San Diego Home Remodeling, we rely on professional-grade materials that last through San Diego’s sun, rain, and everything in between.
How to Build a Floating Deck in Just 8 Simple Steps
Building a floating deck is easier than most people think and when done right, it can completely transform your outdoor space. Whether you’re exploring floating deck ideas for a small backyard or planning a larger platform for gatherings, this step-by-step guide will walk you through how to build a floating deck with confidence and clarity.
1. Plan and Mark the Area
Start by choosing a flat, well-drained spot in your yard. Use stakes and string to mark the perimeter of your deck layout; this will guide every next step.
Pro Tip: Double-check your measurements against your floating deck blueprints to ensure accuracy.
2. Lay the Foundation
Place your deck blocks or concrete pads evenly across the marked area. These will support the weight of your deck without needing to dig holes.
Pro Tip: If you’re working on a slope or soft ground, consider spacing the blocks closer together for extra stability in your floating deck using deck blocks setup.
3. Add Gravel for Drainage
Roll out landscape fabric over the ground and cover it with gravel. This helps prevent weeds and allows water to drain properly under your floating decking.
Pro Tip: Use about 2 inches of gravel to improve drainage and extend the life of your deck.
4. Install the Frame
Using pressure-treated lumber, construct the outer floating decking frame and place it directly on the deck blocks. Make sure it’s level on all sides.
Pro Tip: Secure corners with galvanized brackets to prevent shifting over time, especially in high-traffic areas.
5. Add Joists
Install joists inside the frame, spacing them about 16 inches apart for strong support. Joist hangers help keep them in place.
Pro Tip: Use a level after every few joists to keep your floating deck construction even from side to side.
6. Secure the Deck Boards
Lay your decking boards across the joists and attach them using deck screws. Start at one end and move across slowly for even spacing.
Pro Tip: Leave a small gap (about 1/8 inch) between boards for water runoff and wood expansion.
7. Trim Edges and Clean Up
Once all boards are secured, use a saw to trim the edges neatly. Sand any rough corners or surfaces.
Pro Tip: This is a great time to sweep off sawdust and check for loose screws.
8. Optional: Add Finishing Touches
To finish your floating deck ideas, consider adding a railing, stairs, built-in benches, or a weatherproof sealant. These extras boost comfort and safety.
Pro Tip: For larger decks or elevated designs, consult a pro who knows how to build a deck on the ground to code.

How to Choose Materials for a Floating Deck
Picking the right materials is one of the most important parts of building a ground level deck that lasts. Most DIYers choose between pressure-treated lumber, redwood, cedar, or composite boards. If you’re aiming for natural wood charm, cedar and redwood are great for looks but need regular sealing. Pressure-treated wood is more affordable and strong but needs some upkeep too.
Composite decking, on the other hand, is a top pick for low maintenance and long-term value. It’s weather-resistant and doesn’t splinter or rot, making it ideal for small floating deck projects or larger ones built to last. If you’re wondering, “What’s the best material for a floating deck in San Diego?” go with composite for durability and less maintenance.
At San Diego Home Remodeling, we help homeowners match materials to their needs, budget, and the local climate. Whether you’re following floating deck blueprints or sketching custom floating deck ideas, we guide you in selecting the best finish for your space. A sturdy floating decking frame starts with smart material choices.

FAQs
Can I build a floating deck without a permit?
In many cases, yes. If the deck is low to the ground and freestanding, permits usually aren’t required but always check your local codes to be sure.
What is the cheapest way to build a floating deck?
Keep your design simple and use pressure-treated wood. Basic materials, fewer features, and smart planning help lower the overall cost.
How long does it take to build a floating deck?
For most DIY homeowners, it takes one to two weekends. Having your floating deck blueprints ready and your materials organized can save even more time.
Do I need footings for a floating deck?
Not deep footings. A floating deck using deck blocks or concrete pads is typically enough for support, especially on flat, well-drained ground.
Will my deck move or sink over time?
If you prep your base correctly with gravel and landscape fabric it should stay in place. Good drainage prevents settling and keeps your floating decking level.
