We built a 10x18 ft pergola with one side attached to the house. The hardware and (2) shades are all nicely built and top quality. Our local 4x4 lumber was a snug fit and we had to round off all edges with a 1/4i. Router bit. So that was a couple hours of extra work. We assembled frame on the ground with the covers positioned to size lumber and it took (3) men to tilt it up and secure it to the house. We did the (3) patio pad anchors last after truing up with a level. We were not sure that the roof canvas was going to carry water- it turns out is is a sun shade and water drainage is not a concern (until a freeze) as water comes right thru the mesh. So no slope was needed on the shade.
