Two-Tone Effect

With so many great options, it’s hard to choose just one color of Trex deck boards. Why not pick two? A two-tone effect is a great way to add depth and character to an outdoor living space. It can also be a safety feature, marking where there’s a step, edge or grade change.

Bird House or Bird Feeder

Composite decking boards can be cut, drilled and fastened like conventional lumber. Unlike wood, however, composite boards are defect-free, so you can use every inch. If there are scraps, make them into a birdhouse or bird feeder.

Find Your Zone

When space is available, it’s helpful to partition a deck into multiple living zones— just like you would inside your home. Think of zones for eating, reading and conversation. Outdoor furniture, rugs, patio umbrellas and potted plants can make each “room” feel like its own special place.

Raised Garden Bed

Many, if not most, composite decking boards are suitable for ground contact. Use them to build a raised garden bed that will look great season after season. If you’re short on time, consider buying a raised bed kit.

Well Rounded

Decks don’t have to be square or rectangular. In fact, they often look better with some curves to offset the geometric lines of the house. The rounded edges of this Trex Transcend deck make it a more attractive destination and one of our favorite Trex deck ideas. A cut-out for the tree is also an unexpected yet welcome feature. Here are the complete how-to instructions for building a platform deck.

Cornhole Game

Cornhole boards (aka beanbag boards) built from composite decking boards can live outdoors year-round. That frees up space in your shed or garage for other gear more susceptible to weather damage. (Note: The official rules of the American Cornhole Association say the surface must be plywood to be official.)

Match Game

The railing is an often overlooked part of a deck. While its primary function is practical, deck railings can actually be an aesthetic feather in your deck’s cap. The key is to make it look like it belongs. In this case, the top rail matches the Trex deck while the posts and spindles match the furniture. This makes for a cohesive look.

Step This Way

Wanna make an entrance? Or maybe you’d just like to minimize the length of a staircase. Either way, this landing makes a statement. The integrated lighting and contrasting edges looks good and adds a measure of safety. Learn how to build deck stairs from a pro.

Integrated Planters

Outdoor planters bring nature closer, making a deck seem more inviting. While there are many styles of garden containers available, you can create a sleek, contemporary look with Trex cube planters that match the deck.

The moisture resistance of composite decking boards makes them an ideal material for planters. The boards come in many colors to complement your deck or garden decor and they never need painting.

Break It Up

To break up a large expanse of deck and leave a visual cue to the various outdoor living zones, switch up the direction of the deck boards. You can emphasize the change even more by separating the adjacent sections with a contrasting color, as seen here.

In the Pits

A sunken conversation pit, complete with propane fire table, attracts guests like moths to a flame. No pit? No problem! Trex boards can easily be used for built-in benches even if there’s no sunken space like this one. It will require the support of a wooden frame, however.
