Pergola / August 27, 2018 / JulietteHughes
This does not mean that any type of pergola would be effective. Instead you will have to be careful of what kind of pergola designs you approve of for your garden. Consider the following. 1. What is the exact location of the pergola as per the pergola designs? One of the very common designing flaws with regard to pergolas is that people do not pay attention to the location of various utilities in their gardens. Ideally your pergola should not be built upon any kind of utility related equipment. In fact your pergola should not even be built upon underground piping let alone over ground equipment.
The pergola has evolved from its famous brick and stone posts of 19th and 20th century to modern wood designs of the 21st century. The idea of modern wood design of pergolas is its affordability and increasing popularity in modern garden designs. But because brick and stone are weather resistant hardwoods such as Western Redcedar and Coast Redwood are used instead to match with the pergolas made of brick and stone. As the normal use of a pergola is being an arbor for vines some architects introduced pergolas as a structure made as a protection from rain or direct sunlight.
So while buying wooden pergolas ask their manufacturers if they are partially notched or fully notched. Buyers should be aware that notching creates interlocking joints and this fortifies the structure. Also notching insures that all your timbers stay straight and true over the decades because they cannot move. Most manufacturers skimp on notching partially or completely to reduce their construction costs and will tell you that hardware will take care of the issue. It does not. If just one of your Pergolas timbers has hidden stresses in it (quite common) as it weathers over the years it will turn twist or sag.
