I would recommend this pergola it’s not very hard at all to build but be prepared to work a whole day on it or 2 part days. The BILT app simplifies this so use it don’t use the paper instructions. The only thing that the BILT app lacks is it doesn’t point out all the pre drilled wholes and it really should because it really sets you back if you miss it. Other than that I would build this app over again!
