Please note that the images above show a 24' x 12' pergola (rather than an 18' wide x 12' deep pergola, for which the kit on this page is intended). The width of the pergola will differ from what is pictured above since each of the two pergola roof sections will only be 9 feet wide (assuming the middle posts are placed in the center, which is not required), but the spacing between the roof slats/rafters will match what is shown in the pictures above.

Attaches on the Width Side
This pergola will attach to your home on the 18-foot width side, not on the 12-foot depth side. Click here to see this same pergola kit with the width and depth flip-flopped so the pergola attaches on the 12-foot side.

What's Not Included?
Wood. Wood is a) very expensive to ship and b) readily available to most people at local home improvement and building supply stores. By buying your wood locally, you also have more options on the exact type of wood you'd like that is appropriate for your area's climate.
Anchoring Hardware. While this pergola kit does include stainless steel wood screws for securing 4x4" wood posts into the brackets, it does not include anchoring hardware for securing the base brackets into a secure base (i.e. cement pad, deck, landscape toppers, concrete footing, etc.) or into your home/other structure. This is because the anchoring hardware you need will vary based on a) what type of material you're going into and b) local building codes.
