What Is on the Ground Deck?
Ground-level decking, also known as a floating platform deck, is a deck that is close to the ground. Ground decks are easier to build when the deck is less than 30 inches above the ground because:
- Lower deck height results in a lower risk of injury.
- Low decks usually don’t need stairs or railings for safety (you can still install stairs and railings for decoration).
- Generally, permits are not required for decks under 200 square feet or less than 30 inches in height and not attached to a property. However, for the sake of building safety, it’s a good idea to consult with your local builder to make sure your project is up to code.
Building a deck on the ground is easy and therefore will cost less than an elevated deck. Depending on the size and materials of the deck a homeowner plans to build, building a low deck can cost upwards of $4,000. The most expensive components of building a deck are the railings and stairs. Since ground decks do not require railings and stairs, the material and labor costs of building a ground-level deck are low.

Step-by-Step Ground-Level Deck Construction
The advantage of ground decks is their simplicity. You can easily build a deck in the nicest area of your yard. You can also decorate your house with pavers if you want a more elegant look. Deck ideas ground level depend on your personal aesthetic.
Planning and Design
How will you use the ground deck and assess the terrain? Homeowners need to use this to consider where they want to build their ground-level deck. Since ground-level decking is not attached to the house, you don’t have to worry about door gaps. However, you will need to consider the drainage underneath the deck and may need to add a slope to the ground decks. Building a well-ventilated deck with good drainage will help extend its life.
Choosing the Right Materials
The ground patio is usually low, which means you need to consider the type of wood or composite material used for framing. If the bottom of the deck framing is less than 6 inches above the ground or part of the framing is buried, use pressure-treated lumber. Pressure-treated lumber has a higher preservative content to prevent rot and decay.
Although the code generally does not require the installation of steps, do you want to install a step or two on the deck ground level? If so, consider how you will install the steps. If you are using longitudinal beams to install the steps, do not bury the metal in the ground as it may corrode.

Consider Ventilation for Ground Decking
In some humid environments, the ground under a low-profile deck can become wet. Dampness and moisture are the worst enemies of ground decks as they can lead to mold and rotting of the deck. Make sure there is enough space on the bottom of your ground decks to allow for ventilation and keep the ground dry. This way, your deck will last longer. Generally, if the deck is less than 12 inches off the ground, the perimeter of the deck must be kept free of debris to allow air to flow underneath the deck.
Building a Ground-Level Deck Foundation
A simple ground-level deck foundation can be created by placing concrete blocks in the corners of the deck, or you can place the substructure on gravel for better deck drainage. Next, place stakes in the ground, use the stakes to tension the perimeter, and hang a level. Make sure the platform deck footing is level, and you’re ready to move on to the next step.
Laying the Crossbeams
Place the deck beams on top of the concrete blocks, making sure they are high enough to ventilate the deck. These beams will be used as deck-on-grade framing. Measure diagonally and tap the beams to align them, preferably using temporary wood framing to hold the beams in place. Prevent wood shims underneath the beams if needed to ensure they are level.
Fixing the Joists
Once you have ensured that the crossbeams are level, install corner brackets at the corners where the deck joists meet the crossbeams. This will add extra support to your ground-level decks.
Attaching the Inside Joists
Using joist hangers, attach the deck joists at a fixed spacing. Consult the manufacturer beforehand to ensure that you use the deck manufacturer’s recommended joist spacing. Properly installed joists provide stability and make low decks safer to use.
Laying the Deck
Now that all the bottom framing has been constructed, it’s time to lay the deck. Remove the first section of the decking and align it with the outer edges to ensure that the decking is laid flat. Then, install the deck boards perpendicular to the joists, making sure they are securely fastened. Please leave appropriate gaps to ensure proper ventilation. We recommend you check the manufacturer’s instructions for deck gaps. Then repeat this step to complete the laying of all boards.
Building the Edges of the Deck
After all decking has been installed, trim and sand any protruding parts of the deck. Clean up any discarded deck excess, and now you’re done with all deck installation.
Add Steps and Stairs (If Needed)
If you want to install steps and stairs on a ground-level deck, decide on the number of steps and how they will be built first. Some deck builders add additional bases on the ground or suspend longitudinal beams from the deck.
Enjoy Ground Decking
After completing the deck installation, it’s time to relax and enjoy your new deck.
Ground-Level Deck Ideas for Transforming Your Outdoor Space
Above, we covered how to build a ground-level deck. Ground decks offer a wide range of design options for those looking for the most economical way to expand their outdoor space. But what are creative ground-level deck designs? Before you start building or contracting a new facility, you need to make sure you have the right design in mind.
Minimalism
Many homeowners prefer simple and clean designs, and you can keep things simple by using minimalist ground-level deck ideas. Instead of a railing, build a bench along the edge of the deck. This maximizes seating to create simplicity. Or you can build decks without railings for a clear view of your backyard.
Freestanding Decks
Not all deck spaces need to be attached directly to the house. Building a freestanding deck in your backyard can add unique character to a home.
Consider adding a hot tub to your freestanding deck so you can enjoy the warmth of the tub whenever you want. Or install a gazebo on a freestanding deck to create a charming outdoor space.
Layered Ground Level Deck
Adding the right size to your deck can make the transition to the yard easier. Layered ground-level decks create the feel of a multi-level deck without spending a lot of money. Increase the size of your ground-level decks by dividing them into sections of different heights. Split-level ground decks can be built by designing one part of the deck one step higher than the other.
Low Decks with Kitchens
Creating a ground deck with an outdoor kitchen allows you to better dine and cook outdoors.
Consider adding outdoor cabinets that can add extra outdoor storage space. Or add grills that fit the architectural style of your outdoor kitchen, such as charcoal grills and gas grills. It’s important to note, however, that using a grill on a deck can be dangerous.
Summary
A ground-level deck is one of the simplest and most affordable outdoor projects a homeowner can take on. Because the structure sits close to the ground, it typically does not require railings, deep footings, or building permits, all of which reduce both cost and complexity.
EVODEK composite decking is well-suited for ground-level applications. The capped co-extrusion surface resists moisture, mold, and fading even in close-to-ground conditions where humidity is higher.

FAQ
How much does it cost to build a ground-level deck?
A basic ground-level deck costs roughly $15 to $30 per square foot using pressure-treated wood, or $25 to $45 per square foot using composite decking. For a 10×12 ft deck, expect to spend $1,800 to $5,400 total, depending on materials. Ground-level decks are cheaper than elevated decks because they do not require posts, railings, or deep concrete footings.
Do I need a permit to build a ground-level deck?
In many areas, no. Most municipalities exempt freestanding decks that are under 200 square feet and less than 30 inches above grade. However, rules vary by location. Always check with your local building department before starting. Even if a permit is not required, your deck must still comply with local building codes.
How far off the ground should a ground-level deck be?
Aim for a minimum of 4 to 6 inches of clearance between the ground and the bottom of the joists. This allows enough airflow to keep the substructure dry and prevent mold. If your deck is less than 12 inches from the ground, keep the full perimeter clear of debris and vegetation so air can flow freely underneath.
