The provided instructions are good enough for a chemical engineer like me. Some basic measurement and spreadsheet calculations, and a creative and artsy mind (and driver and drill) are all you need to build this arbor. They allow me to be creative in selecting any number of slats on the canopy (I used 12), as well as in spacing the horizontal slats on the trellis too. I built it in 3 hours, without anchors (yet). Only the last step requires another adult to help. It provides some shades and a warm welcome itself, as my young kids now already love to rest on a long bench underneath the arbor, before our grapevines can grow over it. Worth every time and penny. The color also blends well with my other teak furniture.
Found the instructions highly inadequate for myself. Lots of "approximate" inches. Probably easier for someone with experience. But very beautiful piece.
For assembly I was careful to follow the directions and it went together very nicely. Then I raised it put each corner on a brick set in the soil, all four being level. Then I secured 3 of the 4 legs (one was close to tree roots so I skipped that one) to fence stakes pounded in 2 - 2 1/2 ft to anchor my arbor. Make sure it is level and well anchored. It is a thing of beauty! It even has a nice cedar scent.
