How to Build a Freestanding Deck
A freestanding deck should be about more than just the structure of your deck. It is also about how much you enjoy it and how easy it is to maintain. There are numerous factors that determine whether or not a freestanding deck is the right option for you. The most important thing to consider when building a freestanding deck, besides what you want from it and how valuable your free time is, will be whether or not it can support the weight of all the people standing on it at once.
Building a deck can be a great project to take on if you’re looking to improve your home and make your outdoor living spaces more convenient. However, a free-standing deck has a lot of unique elements that need to be addressed in addition to the traditional decking and structure.
🛠 What This Is About
A freestanding deck is a self-supporting structure not attached to a house. It’s great for open yards, pool decks, or creating a garden oasis.
🧱 How It Works
Freestanding decks stand alone without a ledger board connecting to a house. They can be ground-level or raised, placed anywhere in your yard, and need space for airflow if near a house. Ground-level decks are cheaper since they skip extras like railings or stairs.
📋 Materials or Tools Needed
- Pressure-treated lumber (for frame and decking)
- Concrete blocks or piers (for foundation)
- Galvanized screws/nails (for assembly)
- Joist hangers (for securing beams)
- Post anchors (for attaching posts to piers)
- Shovel, level, drill, saw (basic construction tools)
- Measuring tape and string (for layout)
- Gravel or mulch (optional, for ground prep)
⚙ Step-by-Step Instructions
- Plan the Deck Location
- Choose a flat spot in your yard or near a pool.
- Keep a few inches from the house for airflow.
- Measure and mark the deck size with string.
- Prepare the Ground
- Clear grass, rocks, or debris from the site.
- Level the ground or add gravel for drainage.
- Set the Foundation
- Place concrete blocks or piers at corners and every 4-6 feet.
- Use a level to ensure piers are even.
- Attach post anchors to piers.
- Build the Frame
- Install pressure-treated posts in anchors.
- Attach beams and joists with screws and joist hangers.
- Ensure the frame is square and level.
- Lay the Decking
- Place deck boards across joists, leaving small gaps for drainage.
- Secure boards with galvanized screws or nails.
- Finish the Deck
- Sand rough edges if needed.
- Apply sealant or stain for weather protection.
- Add Optional Features
- Add furniture, planters, or lights for a garden oasis.
- For pool decks, ensure sturdy access points.
Before constructing a deck for a low cost, there are a few extra things to take into consideration:
Dimensions
What dimensions do you require for a deck to fulfil your requirements? If it’s the most cost-effective approach to construct a deck, are you willing to make a compromise in terms of size? There is a possibility that the value of your home and property will increase if you construct a sizable deck. So, if you ever decide to sell your house, you will be able to get back the money you spent on the deck. While searching for ideas for decks on a budget, this is something to take into consideration.
Form or form
Is it possible to construct a deck that is either square or rectangular in shape? Then again, does your yard call for a deck that is of an irregular shape?
How tall
Is a deck that is located on the ground level suitable for your requirements? This would be the most cost-effective method of constructing a deck. If you require an elevated deck, you will be required to spend more money, and you should certainly consider getting the support of an expert when dealing with this kind of deck.
Material Be familiar with the many kinds of materials and the expenses that are involved with them.
In the process of constructing a low-cost deck, what kinds of additional components will be necessary? If you do require steps, how many will you need and how broad will they be? Are you in need of railings? And if so, what kind of railings are they? Various materials such as wood, glass, aluminium, iron, etc.
Deck that is 24 feet by 18 feet and does not require any upkeep, with a fireplace built in.

Designing a freestanding deck
The first step in designing a freestanding deck is deciding where to place it on your property. As with any home improvement project, you should choose the location carefully because moving it later is not an option once it’s built.
A freestanding deck can be attached to your house or detached from it by several feet or more. In both cases, you need to make sure that the building code allows such installations in your area. You also need to consider how much space will be available for walking around the structure as well as how much sunlight it gets during different times of year (in hotter climates).
Building a freestanding deck is a great way to build your own outdoor space. The best part about building your own deck is that you can customize it to fit your needs and style. You can choose from many different types of materials and designs.
Freestanding decks are also called independent or detached decks because they do not attach to the house. They can be used as an extension of your home or as a standalone feature in your yard, depending on how much room you have available.
If you want to build a freestanding deck, here are some things to keep in mind:
Building Codes: Check with your local city or county for building codes concerning freestanding decks before you begin construction. Some places may have specific requirements for where the house ends and where your deck begins. These requirements may include distance from the house, height restrictions and other factors that affect how big or small your deck can be.
Free-standing decks are typically built on a concrete pad, rather than directly on the ground. Although the structure is freestanding and can stand alone without support from your home, it requires more framing in order to support the weight of the deck.

The type of framing you use will depend on how much weight the deck will hold and how much space is available around it. The most common types of framing include post-and-beam, which uses posts that are connected by beams; attached joist framing, which attaches to an existing wall; and cantilevered framing, which uses beams or posts at each end of the deck to support it from below
A freestanding deck is a deck that is not attached to any other structure. It may be built in front of or next to the house, but it is not part of the house.
Freestanding decks are often built on stilts and are usually open in the back. They can be built as a single level or multi-level deck. The most common material used for building them is wood, but with today’s technology, there are many different materials that can be used.
Free-standing decks can be built on any level surface and they are perfect for those who want an outdoor living space without having to worry about being connected to the house.
