Please note that the images above show a 24' x 24' pergola (rather than an 18' wide x 22' 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 roof of this pergola kit is only intended to span the pergola's 22-foot depth out from the house (rather than a 24-foot depth as shown in the pictures). That said, the spacing between slats/rafters will be very similar to what is shown in the pictures.

Want a Larger 6x6 Frame?

Click here to see this exact same pergola kit with a larger frame for 6x6 wood posts (instead of 4x4 wood posts).

Attaches on the Width Side

This pergola will attach to your home on the 18-foot width side, not on the 22-foot depth side. Click here to see this same pergola kit with the width and depth flip-flopped so the pergola attaches on the 22-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.

Required Lumber & Estimated Total Cost

As noted above, wood (lumber) is NOT included in this pergola bracket kit (nor is the hardware you'll need to anchor the base and wall-mount brackets).

Before you can build your pergola, you'll need to purchase the following items from a local building supply store or lumber yard:

- Six (6) 8' long 4x4 posts
- Four (4) 10' long 4x4 posts
- Six (6) 12' long 4x4 posts
- If you select a roof... Twenty to sixty-eight (20-68) 10' long 2x4 slats *OR* sixteen to thirty-two (16-32) 10' long 4x4 posts - dependent upon your roof selection
- Anchoring hardware (36 pieces)

The estimated cost for the above lumber and anchoring hardware is $671 - $1472 (depending on the roof you choose) OR $544 if you purchase the frame only (no roof).

Together with the cost of this Zen Pergolas bracket kit, the estimated TOTAL ALL-IN COST for your pergola is $1950 - $3903 depending on your roof selection (or $1343 for the frame only). This is only an estimate... actual costs will vary depending on the type of wood you buy, your location, local stores & availability, and various other factors.

4x4 mount brackets very well made and finished
I would highly recommend this product.
The one suggestion I have to make them superior change the screws from Phillips to torx

This kit is perfect for building a pergola type structure. All the joints are tight and straight. On shipment the box containing the rafter supports broke open in the ups truck and scattered all over the truck. I had to refuse shipment on that box. Customer service contacted me and had a replacement box shipped with in a day that they were notified of the problem. Recommend both the product as well as their customer service.
