Composite Decking Designs In Outdoor Living Spaces

July 21, 2025

No matter what the view is from your window, whether you have a small lawn or a beautiful body of water. Outdoor composite deck designs are a great addition to your home. Many homeowners choose composite decking material because it does not require regular maintenance, which will save the homeowner more time and maintenance costs.

Composite decking boards allow for a true wood look, and they contain many customizable components. From the shape of the deck to the choice of lighting and railings, your composite deck can be your best masterpiece.

Composite decks come in a wide variety of colors and finish options to complete a wide range of deck design options. As a result, it has become one of the most popular deck types among homeowners.

How to Start Your Deck Design

Gorgeous composite deck boards start with a great plan, and the following points need to be considered when planning your ideal deck.

Size and Use

How do you want to use your deck? Do you plan to do a lot of grilling and entertaining in the outdoor living space? Or do you just want a small backyard retreat to soak up the sun? Your purpose will determine the size and scale of your outdoor composite deck.

Deck Budget

Do you have a set budget? This may affect the size and scope of your composite deck. Or maybe you want to incorporate additional features, which can also raise the cost of your new deck installation.

When planning your composite decking, it’s important to consider not only the cost of materials but also the cost of labor. If you plan to do your own DIY installation, then you can lower your budget a bit. But the build time will usually take longer than if you hired a professional.

Get a Local Permit

In most cases, you will need to get a permit to build a deck. Building codes are not the same in different areas. Therefore, it is necessary to obtain a building permit prior to constructing a deck in order to avoid any problems that may arise afterward.

So you’ll need to complete your decking design and then take the blueprints to your local building office to make sure it meets safety codes and apply for the proper permits.

Start time

The time it takes to build a deck depends on a variety of factors, including the size, shape, and components of the deck, the number of people building it, and the skill level of the people involved. If you want to enjoy your deck in the spring and summer, then you will need to start preparing for the build in the winter.

Weather conditions may affect the timing of your project, and rocky terrain and ensuring ground levels will also increase the time to completion. If you live in an area with cold winters, you may also need to consider the time it takes for the ground to thaw and drain before you can begin.

Color Selection

Deck color choice is important – do you prefer subtle details or something bolder? Composite deck material is available in a range of stylish color options. Warm collections such as oak, walnut, or teak are perfect for a home getaway, while colors such as lime and rock grey create a more modern, sophisticated feel.

Of course, you don’t have to decide on just one color. In fact, mixing colors can add creativity to your design. Certain combinations can provide an ultra-modern look to your garden, especially through the use of interesting contrasts of light and dark.

In larger gardens, an all-black deck may look a bit heavy. But by pairing it with lighter colors, you can inject a vibrant personality into your space.

Functionality

Keep in mind that good outdoor decor is designed to be practical for your guests. You will want to be able to maintain a good atmosphere at night, so make sure you complete the effect with dramatic lighting effects. Think carefully about the kind of feeling you want your space to evoke.

A covered pergola structure may also be what you need. Do you need a porch to shade you from the sun on hot summer days so you can cool off on the deck? If you have a high deck, then you will also need a deck railing to keep you and your family safe.

Finally, when planning your deck, always keep in mind the purpose of the finished product: to relax and entertain! Try to build your space around spaces that can be enjoyed alone or by multiple people together.

Popular Deck Design Ideas

If you have trees or plants in your yard, then you can choose to install decking around the trees or create sunken flower beds for the plants to make a different design effect for your deck space. If you want to take it a step further, you can create decorative insert features such as planters or even a larger range of hot tubs!

Color and insert features are a wonderful way to experiment with your deck design, but how should you layout and design patterns? Out of the simplest vertical or horizontal deck designs, you may choose to experiment with other styles. Let’s take a look at the different deck design options next.

Design a Theme Using a Single- or Multi-width Deck

The first consideration when designing a deck is which boards to use and how to lay them. Changing the size and color of the planks is an easy method to add interest and texture to a deck design. Previously, deck designs were confined to one width of planks. Decking materials are now available in a variety of widths, allowing for more creative and sophisticated designs.

COOWIN offers a large selection of composite decking boards in a variety of widths. Different widths of decking boards can be mixed to form a design or give depth.

Create a Unique Deck Pattern

Putting the decking boards together in a pattern results in a fully unique deck. You can use a single design throughout the deck, or you can employ inlays to create focus points and separate dining and seating spaces.

Keep in mind that decks with more elaborate patterns require more joists, which might increase construction expenses. Nonetheless, we believe it pays to adopt these common deck layouts.

Diagonal Deck

Diagonal decks use boards at a 45-degree angle to the deck structure, giving them a sleek, modern appearance. Diagonal planks direct the eye outward, making a room appear larger.

This design characteristic can be found in many mid-century residences. This style is ideal for tiny or narrow decks since it gives the illusion of a larger space.

Pin Stripe Deck

A pinstripe deck design is an excellent technique to keep things understated while making something appear more fascinating. You may make stripes by alternating between narrow and wide planks. For more complicated stripes, combine two or more sizes. This style is suitable for both classic and modern homes.

Herringbone Deck

The Herringbone Deck design resembles a basket weave, with small deck boards set at a 45-degree angle to form a repeating “V” shape. It is a complex design that looks exquisite as an accent and makes a bold statement as an overall design. This pattern is suitable for both classical and contemporary building types.

Photo Frame Deck Design

The picture frame deck pattern is a simple, low-cost deck arrangement in which deck boards form a “frame” around the deck’s edge. Choosing an edge that is distinct in color from the rest of the photo frame might help it stand out. Alternatively, use the width of the boards to make a picture frame that is two or three boards wide.

Picture frame margins are not only attractive, but they also protect the ends of deck boards from the elements.

Tile Deck Patterns

The tile deck pattern generates a square or rectangular pattern by separating each deck board with a framed grid. By repeating the same squares, this geometric pattern breaks up the expanse of a big deck. A bold border color will draw attention to the image, whilst a consistent deck color will soften the impression.

Deck Inlay Design

A deck inlay is a decorative pattern or contrasting color deck board that is put into the surface of another deck. Designers employ inlays to create focal points or to indicate routes and seating areas. Inlays are also a good approach to reducing seams to a minimum on larger decks.

If a board does not fit across the entire deck, a decorative inlay in the center provides a natural break in the design. Deck inlay designs allow you to be creative by combining various patterns and colors to make the design stand out.

Create Complementary Custom Railings

Deck railings enhance the appearance of your outdoor space while keeping people safe. Choosing a railing material that complements the style of your deck can help the railing to stay in place for years to come.

COOWIN’s composite and composite railings have replaceable posts, caps, and padding.

Increase Functionality with Built-in Deck Benches

Having furniture on your deck that you can sit on and eat off of will make it an ideal spot to unwind. Outdoor sitting fades and wears out, and outdoor furniture needs maintenance. Built-in benches can survive for at least 25 years, much like a deck.

A typical bench is affordable and provides seats without blocking the view. To soften the edges of your deck, consider installing planting boxes. The boards’ color and substance should complement the deck to provide an aesthetically pleasing overall effect.

COOWIN’s high-quality composite decking boards can also be shaped into curved benches, which is a more expensive choice. Benches can be designed to accommodate an oval dining table or a round gazebo. Pillows and other soft materials can be placed on the bench’s backrest to increase comfort. With these built-in semi-circular benches, everyone can comfortably sit around the fire pit.

Shade Covers Can Make a Deck Look Nice

Building a shady space on your deck is a wise decision. A built-in shade structure outperforms a parasol in terms of longevity and allows you to utilize the deck during the day. Additionally, it protects the deck from the elements. If you’re seeking shade, here are some popular choices:

  • The awnings. Made of a stretched cloth with a frame linked to the home. Some awnings can be retracted to partially shade a porch, patio, or deck from the sun.
  • The pergola. This building has a slatted roof and corner posts. It can be shaded by hanging shade cloths or placing plants on top.
  • Attached high building. This is a roofed structure that is attached to the home and supported by posts, similar to a porch.
  • Roofing extension. An engineer may be required to design the structure to match the residence.

Deck Design and Landscaping

One of the most significant factors when designing a deck is that it is built in an area with a decent view. This allows you to enjoy your outdoor living space while also admiring the landscape in the distance. This will boost your comfort and make you satisfied with your deck design.

For example, if the property is situated on a hill overlooking a river, you may decide to construct a balcony deck. You can then spend your weekends relaxing and having fun. Join your family and friends on the balcony deck to appreciate the view in the distance while sipping coffee and talking.

Of course, a deck this high needs protective railings. In addition to standard deck railings, you may wish to consider clear glass railings. Not only will it keep you secure, but it will not obstruct your natural vision.
