Please note that the images above show a 12' x 24' pergola (rather than a 10' wide x 20' deep pergola, for which the kit on this page is intended). The number of roof rafters/slats will differ from what is pictured above since the two roof sections are only intended to span the pergola's 20-foot total depth (not a 24-foot depth). That said, the spacing between slats/rafters will be very similar to what is shown in these images.

Attaches on the Width Side
This pergola will attach to your home on the 10-foot width side, not on the 20-foot depth side. Click here to see this same pergola kit with the width and depth flip-flopped so the pergola attaches on the 20-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.
