Increase the height of pergola kit


I'm installing a 10x12 pergola kit into my concrete patio.
The only problem is the pergola is only 7.8' height while I'm expecting to install at about 10'. Is there any solution to extend the length of the pergola post for 2.2' more to a total of 10'?

Below is the kit I'm installing:

Any thought to building something from scratch?

Yea, once you have to start modifying a kit especially a major structural part like the legs you have to question if a kit is the best way to go. One option is to pour concrete piers using cardboard Sonotube as the form and have them extend 2' above grade to give you the extra height. I wouldn't try adding on to the legs of the kit. It will be difficult to get anything to match and look right then there is the structural issue.

I'd consider discarding the kit's posts and buy longer ones. Adding to existing posts isn't a viable option!

I agree with Marksr, although finding good quality cedar in 6x6 will be a test. Your profile is not complete so we don't know where you are located. In the western US, you may find the cedar and redwood more easily. Do not extend the existing posts. Since you are building it from a kit, duplicate drilled holes, etc for ease of assembly.

If they're replacing all of the posts like marksr suggested or making concrete columns like pilot dane suggested certainly select the 2 best alternatives. Either one would work quite well it all depends on how you want the completed pergola to look. If you go the alternative of concrete columns you could either make them round or make them square and brick face them.

Dane and Msradell bring up good points. Since you are paying for cedar posts with the kit, building footers and columns of concrete, and facing them with stone or brick would look inviting and unique, saving money on cedar posts.
