Pergolas are usually, though not always, best for Asian-themed yards. These structures use vertical posts to support a cross-beamed open top. Rather than providing shade and protection from the elements, they are often used to provide an appearance of elegance or to support grape vines, roses, ivy or other climbing decorative plants.
The nice thing about a pergola is that it can be used in a range of yard sizes. They are ideal for placing beside swimming pools, over wishing wells, or over patios.
