Additional Information

Not Included in this Kit

Wood - Lumber 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.). 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 Cost

As noted above, wood (lumber) is NOT included in this pergola kit (nor is the hardware you'll need to anchor the base brackets). Before building your pergola, you'll need to purchase the following items from a local building supply store or lumber yard:

  • Nine (9) 8' long 4x4 posts
  • Twelve (12) 10' long 4x4 posts

The estimated cost for the above lumber and anchoring hardware is $645. Together with the cost of this Zen Pergolas kit, the estimated total all-in cost for your 20 x 18 pergola with canopies (4) is $2,194. This is only an estimate; actual costs may vary depending on the type of wood you buy, your location, local stores & availability, and various other factors.

The kit includes four (4) premium quality charcoal gray shade canopies to mount to the top of the pergola. Most customers will opt for two 8' x 10' canopies and two 10' x 10' canopies, but you may also choose to instead get one 8' x 8' canopy, one 8' x 10' canopy, one 8' x 12' canopy and one 10' x 12' canopy. The shade canopies are made of fade-resistant 180 GSM High-Density Polyethylene (HDPE) knitted fabric that blocks up to 95% of UV rays and is permeable to prevent rain from pooling on top. Each side of the canopies has 4 straps to keep the canopies tight and prevent drooping. The kit also includes all necessary corner and side accessory mounts (including screws) to secure the canopy straps to the corner brackets and beams of the pergola.

Please note that the images above show a 24' x 24' pergola (not a 20' x 18' pergola with canopies for which this kit is intended).
