When planning to build an outdoor living space, one of the first things on your mind is likely the budget. You want a space that’s both beautiful and functional, but the price tag can vary widely depending on your choices. If you’re eyeing a 20×20 outdoor deck, you’re probably wondering how much it will set you back.
A deck that size provides plenty of room for entertaining, relaxing, or even hosting family dinners outdoors. But, like any home improvement project, costs can fluctuate depending on several factors. Whether you’re considering materials, labor, or special features, understanding how these elements contribute to the total cost will help you plan and make informed decisions. Let’s break down what to expect when it comes to the total price of a 20×20 outdoor deck.
What Is an Outdoor Deck?
Before we dive into the costs, let’s briefly talk about the type of deck we’re referring to. A deck is a flat, outdoor surface, often made of wood, that’s raised off the ground and attached to the exterior of your home. Decks come in various sizes and can be used for everything from simple seating areas to elaborate outdoor kitchens. In this case, we’re focusing on a 20×20-foot space—400 square feet of outdoor living.
When it comes to materials, there’s a wide variety to choose from: wood, composite, and even PVC. For this guide, we’ll talk about the cost for a variety of materials that could be used for your deck, with an emphasis on quality, longevity, and ease of maintenance.
Factors That Influence the Price of a 20×20 Outdoor Deck
So, how do you get from dreaming of an outdoor space to having a solid, finished deck? Several factors can impact the overall cost, and understanding these elements will help you make the right choices while staying within your budget.
1. Size and Design of the Deck
The size of the deck is one of the biggest cost drivers. A 20×20 deck equals 400 square feet, which is pretty large and provides ample space for seating, dining, and entertaining. Larger decks require more materials, which naturally increases the price.
The design also matters. A simple square or rectangular deck will cost less than a deck with multiple levels, custom shapes, or built-in features. Custom designs and features like benches, planters, or lighting can add up in both materials and labor costs.
2. Material Choices
When choosing the materials for your deck, you have several options, each with its own cost range. Here’s a look at some common materials used for outdoor decks:
Pressure-Treated Wood: This is typically the most affordable option for building a deck. Pressure-treated wood is treated with chemicals to resist rot, insects, and decay. It’s easy to work with and can last a long time if properly maintained. However, it requires more maintenance over time compared to other options.
Cedar or Redwood: These are more expensive than pressure-treated wood but offer a natural beauty and increased durability. Cedar and redwood decks resist decay and insects naturally, and they have a beautiful, rich color. However, they also need to be maintained regularly with stain or sealant to protect them from weathering.
PVC or Vinyl: These materials are more expensive but require almost no maintenance. They are resistant to moisture, insects, and rot, and they come in a variety of colors and finishes. PVC and vinyl decks are typically long-lasting, but they cost more upfront than wood.
Engineered Wood: This material combines wood fibers and plastic for a durable, low-maintenance alternative to traditional wood. Engineered wood is generally more expensive than regular wood but offers a better look and longer lifespan with less upkeep.
Each material type has its pros and cons, and the one you choose will significantly affect the cost. Higher-end materials may come with a higher initial price but often save you money in maintenance costs over the years.
3. Labor Costs
Labor is one of the major components of the total price when building a 20×20 outdoor deck. Depending on your location and the complexity of the design, labor costs can vary widely. On average, you can expect to pay anywhere from $3 to $8 per square foot for labor, though this could be higher or lower depending on where you live and the experience of your contractor.
For a 20×20 deck (400 square feet), the labor charges could range from:
Low-End Labor Costs: $1,200
Mid-Range Labor Costs: $2,000
High-End Labor Costs: $3,200
If you’re going for a more intricate design with custom features, like built-in seating or multi-level structures, the labor costs can rise accordingly due to the additional time and skill required.
4. Additional Features and Upgrades
There are plenty of ways to customize your deck with added features that will increase the overall cost. These include:
Railings: Adding railings to your deck not only improves safety but also boosts the aesthetic appeal. Railings can be made from a variety of materials, including wood, vinyl, or metal. They can cost anywhere from $1,000 to $3,000 for a 20×20 deck, depending on the style and material.
Stairs: If your deck is elevated, stairs will be necessary. Basic stairs might cost as little as $500, but more complex or custom stairs could push the price closer to $2,000.
Lighting: Adding integrated lighting to your deck is a great way to create a relaxing ambiance. Lighting options range from step lights to post-mounted fixtures and can cost anywhere from $300 to $1,500, depending on how elaborate you want the setup to be.
Built-In Furniture: If you’d like to add built-in seating, tables, or planters, this will be an additional cost. Custom furniture can be a stylish and functional addition to your deck, but it typically comes at a higher price. Expect to spend anywhere from $1,000 to $3,000 for built-in furniture, depending on the complexity and materials.

Tips for Saving Money on Your Outdoor Deck
If you’re working with a budget, there are a few ways to save without compromising the quality or appearance of your deck:
- Choose More Affordable Materials: Opt for pressure-treated wood or mid-range materials if you want to save money. These materials can still give you a great-looking deck without the high price tag.
- DIY Installation: If you’re handy and have some experience with home improvement, you could save on labor costs by building the deck yourself. However, be mindful of local building codes and permits, and make sure you’re up for the task.
- Keep the Design Simple: Stick to a basic rectangular shape without too many custom features. Extra details can increase both materials and labor costs.
