There is an option to construct the terrace canopy with prefab kits and construction instructions from the online shop. Materials and dimensions have already been calculated, so construction can start immediately. However, kits leave little room for individualization. If you want to construct the terrace canopy without a kit, you will need a mortar mixer, spades, a drill, spirit level and ruler, a saw, hammer, wheelbarrow, clamps, cutter knives and, last but not least, appropriate protective clothing.
However, if you don't have basic crafting skills, you should refrain from attempting any kind of DIY construction, especially if it's just a privacy screen: In this case, a sun canopy or awning is easier to mount.
