If you're dreaming of adding a deck to your outdoor space, your first move is to plan a deck build. This process is crucial and involves more than just picking materials; it’s about designing the layout, considering how you will use the space, and planning for permits. Whether you’re tackling the project yourself or hiring a contractor, following a well-thought-out plan ensures a smooth build and a deck that lasts for years. Let’s dive into the steps involved in how to plan your deck build.
Step 1: How will your deck be used?
Before you start designing your deck, it’s essential to think about how the deck will be used. The purpose of your deck will directly impact its size, layout, and special features. Consider the following questions:
- Will the deck be attached to your house, or is it a freestanding structure?
- Are you planning to host large parties or just have a small, cozy retreat?
- Do you need built-in features like shade or seating?
- Will the deck need utilities like electricity or plumbing for things like a hot tub or outdoor kitchen?
- Do you plan to use it year-round, which may require specific features for weatherproofing or insulation?
Answering these questions will give you a clearer idea of what your deck needs to include, helping you refine your design and plan for any unique requirements.

Step 2: Determine if you will DIY your deck
When planning a deck build, deciding whether to DIY or hire a contractor is a big choice. If you’re considering a DIY project, you’ll need to assess your skills, tools, and the time you can commit.
If you plan on hiring a contractor, they can help guide you through the entire process, from planning to installation. However, it’s still beneficial to have a vision in mind before bringing in a professional. A good contractor will appreciate knowing what you envision for your deck’s design and functionality.
Step 3: Design your deck’s layout
Once you’ve determined how you want to use the deck, it's time to design the layout. The most common deck sizes are 10’ x 10’ or 12’ x 12’, but you may need something larger or more complex, like a multi level deck. To help visualize your layout:
- Start with a basic sketch on graph paper.
- Use online deck design tools or deck visualizers to refine your ideas.
- Consider your backyard’s size and how the deck will integrate with existing landscaping.
Think about the flow of traffic, ensuring your deck has enough space for furniture and that it doesn’t overcrowd your yard. You’ll also want to think about access points, privacy concerns, and any additional features like railings, stairs, or built-in seating.
Step 4: Select your decking materials
Choosing the right decking materials is a crucial part of planning your deck build. The material you select affects the aesthetics, durability, maintenance, and overall cost of your deck. Common decking materials you’ll find in a home center or lumberyard include:
- Pressure-treated lumber: This is a great, popular, and affordable option known for its strength and resistance to rot and insects. It also boasts a natural wood aesthetic. ProWood® specializes in pressure-treated lumber.
- Composite decking: Made primarily from recycled plastics, composite decking requires less maintenance but is more expensive upfront. It’s a good option for those looking for a low-maintenance deck that lasts for many years.
Your deck’s substructure, including posts and joists, will likely be built with treated lumber to ensure stability and longevity. Consider all factors, from appearance to maintenance, when making your material choice.

Step 5: Set a budget and timeline
With your design and materials in mind, the next step is to set a budget and timeline. Start by creating a material list based on your deck plan, then use online resources to estimate costs. Don’t forget to include:
- Materials and supplies (nails, screws, fasteners, etc.)
- Labor costs (if hiring a contractor)
- Permits and inspection fees
- Additional features (electrical wiring, plumbing, lighting, etc.)
Set a realistic timeline, considering delays like weather or material delivery times. Knowing your timeline and budget will help keep your project on track and prevent unexpected expenses.
Step 6: Check local building codes and permits
Before you break ground, make sure you’re aware of your local building codes and permit requirements. Your municipality may have specific guidelines regarding deck height, distance from property lines, railings, and more. Typically, you’ll need to submit your deck design for permitting before you can begin building. If you’re hiring a contractor, they will usually handle this step for you.
It’s essential to follow local regulations to avoid fines and ensure your deck’s safety.

Step 7: Finalize your plan and start building
Once you’ve completed all the above steps, it’s time to finalize your plan and get to work! Whether you’re doing the build yourself or hiring a contractor, make sure you have all the materials and approvals in place before starting.
