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.
Assembly required/Assembly Instructions: Make sure you have collected assembly instructions from the manufacturers. Usually you can ask for and receive them via email prior to purchasing to see how much work you are in for. Most pergola kits are single day installs. If they are fully erected in the shop prior to shipping out. you should be confident to install them properly. Insist on assembly instructions prior to buying and ask if there is any carpentry work you must do on your end or not. The best kits are just like giant Lego sets that you just have to re-erect: no sanding. sealing. cutting. or drilling needed.
Notching: Another important point to consider is notching. Notched pergolas last for longer times and have greater wind resistance capacity. 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 Pergola`s timbers has hidden stresses in it (quite common). as it weathers over the years. it will turn. twist or sag. This will cause your beautiful Pergola`s lines to be ruined.
As a permanent architectural piece to a garden. pergola designs have evolved throughout the centuries making it more appropriate for gardens and environmental designs. During medieval and renaissance period. pergola designs were used by people making curve segments incorporated with green vines. It was usually seen in gardens of Lords living in fortresses. 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.
