Hello, and thank you for your enquiry. Yes, this particular pergola was custom made where the wood frame was constructed first and the contemporary canvas panels were added once the pergola was complete. Having a number of these panels optimizes shade experiences and freedom. Many companies supply these retractable shade canopies in kit form and they are relatively easy to install yourself if you are prepared to read and follow the instructions carefully and methodically! Or if you prefer you can hire a specialist contractor recommended by the supplier. These canopy suppliers commonly also offer a full installation service for the pergola as well as the shade structure. The pergolas are commonly made from wood, steel, or vinyl. The shade canopies can be retrospectively added to existing pergolas as well.
