This pergola took many hours to construct (with instructions that aren’t always super clear), but it’s definitely solid once it’s up! We made a few modifications to ensure that the structure was set solidly in the ground (using pier blocks) and firmly anchored to the house (the hardware it comes with for securing is meant for concrete, not wood siding). TBD on how well the plastic panels will hold up to falling tree debris in autumn, as that part feels a bit flimsy.
