Find the best Outdoor Structures at Costco!
Whether you’re in the market for an all-weather canopy, a hardtop gazebo, or a beautifully designed greenhouse, Costco has the perfect outdoor structure to complement both your lifestyle and budget. Many of our outdoor and garden structures come in easy-to-assembled kits, with pre-cut and pre-drilled pieces, well-illustrated instructions, and necessary hardware. We also offer a large selection of resort-worthy patio and outdoor furniture to help you complete your beautiful new outdoor space.
Add Shade & Privacy to Outdoor Living Spaces
Add shade and privacy to your outdoor living space with a premium gazebo from Costco. With their solid roofs and spacious size, gazebos are perfect for year-round entertaining. You’ll no longer have to worry about dinners being ruined by a sudden rain shower, or kids' playtime being cut short because of too much sun exposure. And you can shop confidently knowing that our gazebo kits have high-end materials, including weather-resistant wood and galvanised steel. Choose between a wood or metal gazebo, and enjoy great features like detachable mosquito netting.
If you’re looking for a structure with a more open feel, consider purchasing one of our pergolas. Their breezy design will create a comfortable space where you can enjoy soft, filtered sunlight. And the pergola’s lattice roof is perfectly designed to support climbing vines, flower baskets, or hanging lights. Available in attached and freestanding styles, pergolas can be placed almost anywhere, from decks to garden areas. We have small pergolas for intimate settings, and larger sizes that can accommodate dining tables or hot tubs.
Costco also has smaller-scale structures that look beautiful in any setting. Placing an arbour at the entrance to a pathway, garden or patio area, is a lovely way to welcome guests. Its open design allows flowers and vines to grow up and around the frame, helping it to blend in with the surrounding landscape.
Enjoy Year-round Gardening
If you love organic produce, or simply enjoy gardening, then a new greenhouse from Costco is just what you need! The climate controlled environment of a greenhousecreates the perfect balance of light, warmth, and air circulation. It also allows you to extend the growing season, and produce exotic plants and fruits that would normally only thrive in tropical climates. With Costco’s low-maintenance DIY greenhouse kits, you’ll enjoy helpful features, including adjustable window louvers for regulating humidity and air flow.
