If you’re building a new composite deck, you may find yourself with some different-sized deck pieces leftover. You may be puzzled about what you can do with deck pieces? Are these pieces just good for the trash bin, or can you use them to upgrade your new outdoor space further?
The excess composite decking is perfect for nonstructural outdoor DIY projects such as storage boxes, yard paths, pool covers, plant boxes, and birdhouses. Composite decking is weatherproof, mold-resistant, hardwearing, and is great for DIY projects as it can withstand sun, snow, or rain.
Suppose you find yourself with a stacked pile of composite decking in your yard or wonder what to do with leftover decking when your deck has been completed. Keep reading as we will discuss a couple of at-home projects perfect for using excess composite decking. In our opinion, these projects will turn out better than using standard wood.
Smaller DIY Projects To Make with Leftover Composite Decking Materials
Composite decking is ideal for outdoor projects due to its durability and resistance to moisture, mold and mildew. Using composite decking means a quick and hassle-free project, as they do not require any sanding, varnishing, staining, or painting.
Unlike wood that may have knots, cracks, or dead spots, leaving some parts unusable, composite decking boards are consistently and precisely manufactured, meaning you can use every last piece.
Here are some great DIY projects to try out with your leftover TimberTech composite decking:



Rectangular flower planters or vertical planters
Planter boxes and vertical planters are an easy DIY project to provide a matching accessory to your deck or outdoor space. The TimberTech composite boards are toxin-free, mold-resistant, and don’t require painting, making them perfect for building a planter box to house your favorite herbs, vegetables, or flowers. You don’t have to worry about wet soil or water decomposing or rotting your planter over the years.
A raised garden bed can be constructed with bigger composite boards leftover. The boards will naturally complement your outdoor living space or house as they will be the same color and grain pattern as your deck.



Shelves
One of the easiest projects to use up smaller pieces of composite decking is to turn them into indoor or outdoor shelves. You could also use the decking to make a weatherproof backpiece to display your house number, or if you are handy with a jigsaw, make your house number out of the decking.
The shelves could be installed as wall-mounted or free-standing, depending on the size and shape. Our favorite feature is that no sanding, staining, or varnishing is required, making this a quick and easy at-home project for all skill sets.



Storage chest
To complement your new or existing TimberTech composite deck, a storage chest made from the leftover decking could be a great addition to store blankets, cushions, or deck accessories. The storage chest could also be used to store pool accessories poolside if required.
A storage chest could also double up as a footrest, coffee table, or additional seating, making for a multi-functional furniture piece for your outdoor living space.



Add a stylish or playful yard path.
Due to the weatherproof nature and durability of TimberTech composites decking, leftover pieces could be joined or cut to size and placed in contact with wet soil to make a path through your favorite parts of the garden. A decorative boardwalk can give your outdoor space, no matter the size, a cohesive and stylish look.
You can get creative with the shapes of your yard path and where it leads. At TNT home improvements, we are partial to a composite decking path leading to a treehouse.



A Tree Swing
If you have a lovely big tree in your yard with the perfect branch to install a tree swing, a good-sized composite deck piece and strong rope can provide countless hours of fun or a quiet place to retreat.



Birdhouse
A fun and simple weekend project for yourself or the family can bring all the birds to the yard with some natural-looking composite decking. A simple rectangle design with a whole for entry is a great way to use the leftover deck pieces. You don’t need to worry about your birdhouse rotting and falling off the tree or growing mold.
Larger Projects To Try With Leftover Composite Decking
If you find yourself with more leftover composite decking than needed for a smaller project or are handy enough, here are some larger DIY projects to try.



Durable garden bench
If you are looking to add the perfect outdoor furniture to your front porch or next to the flower garden, a composite deck bench could be the ideal addition to make a cohesive outdoor space with your deck. Your garden bench will be weather-resistant, durable, and safe.
The construction of a bench does not require many tools or materials, just basic woodworking knowledge. Pieces of composite decking can be joined together with the longer pieces that make up one longer run, just make sure to break on a support joist.



A composite cornhole set
Summer afternoons in the garden can be taken to a new level by adding a cornhole set to the activity list. Cornhole boards can be constructed from your leftover composite decking boards, resulting in a game that you can leave in the garden year-round.
A new surface for an old piece of furniture
You can use your leftover composite decking boards to upcycle a piece of furniture looking worse for wear or match it to your deck. For example, you can replace an old wooden tabletop with a new composite top that is not prone to warping, splitting, or cracking from spilled liquids or wet weather. You can use the excess composite decking to replace worn and rotten wood on deck chairs and benches.



A kid’s playhouse or treehouse
If your kids need extra space to play outdoors or you have a tree that looks a perfect fit for a treehouse, composite decking will be your best friend. Playhouses or treehouses are simple in design, and their size and fanciness can be customized to your needs.
The composite decking will provide a durable, secure, and weatherproof structure for years of play, giving the kids a creative space to let their imagination run. From an aesthetic garden point of view, the playhouse or treehouse will complement the decking.



A pet house
Leftover composite decking can also ensure that ‘mans best friend’ has a custom-made size and comfortable pet house. A composite deck pet house is a great way to provide your four-legged family member with somewhere cool, dry, and warm to sleep or watch over the family.



A feature wall
While you would typically use shiplap or cladding to make a feature wall, leftover composite decking boards can be used to create an inexpensive outdoor feature wall that matches your deck. Depending on the size, you may need to join smaller pieces of composite decking. A feature wall can be an impressive backdrop for a bar, outdoor kitchen, or hanging plants or herbs.
