This wooden pergola was built in the common public area of Cotswold Downs in Hillcrest. The original one had been damaged due to high winds. It was built using H3 CCA Treated pine. Being H3 CCA treated it has a minimum life span outdoors, in the weather, of 50 years. See here for an article on the correct treatment of pine.
We built concrete bases with galvanised steel drag plates set in the concrete. The ground had a slight fall to it so each plinth was set and cast level with each other. The timber sits out the concrete fixed to the drag plates. This should limit the premature rot of the timber and resulted in H3 being used as opposed to H4.
We finished this one with a mineral based Rystix in Imbuia (black) at the client’s request.

A wooden pergola is a structure above that is designed using timber beams, purlins and slats. It is largely decorative as it does not prevent rain and provides limited shade depending on how many slats are installed.
They are sometimes referred to as Sun Screens and can be built in such a way as to offer shade at certain times of the day by adding more or less slats to the top. There are a multitude of designs and they are only limited by ones imagination, and of course budget.
They can be attached to the main building and then supported by posts on the front edge or they can be free-standing with posts to ground. One can install roof sheeting above to keep the rain out, but often it is better to consider an aluminium awning for this application due to cost. A balau pergola is not the cheapest method, but does add a nice appealing underside to your covering.
Wooden pergolas can also be installed using thatching laths to give them a more rustic look and feel.
