Compared to most sunroom iterations, pergolas tend to be a much more budget-friendly option. But they still come with a range of options in terms of type of wood, hardware and accessories, and covering material—along with furniture and features. One of the big choices is covering material. A fabric cover with a mechanical crank for hardware is a reliable, yet versatile, option. A pergola trellis with vine plants is a beautiful, seemingly low-cost option, but beware that the maintenance requirements are considerable.
