Before you get started, here is what you’ll need:

5 x treated fence posts

Timber (treated) for the frame and rafters (the amount will depend on your requirements)

1 box Long timber construction screws

5 pack of Hex Bolts and nuts (as many as required)

Dust free Sander


A range of tools (work bench, saw, spirit level, hammer, ladder, tape measure, clamps and ruler)

To make life easier, we’ve included links to all the products for this project that are available to buy online from ElectricalDirect and our sister site IronmongeryDirect.

Measure Your Space

The first step is to measure and mark out the space that the Pergola will be built in, it can be as big, small, long or wide as you like, as long as you have sufficient space for functionality and structural support.

Time To Dig

When it comes to digging the holes for the fence posts to go in, the depth will be dependent on the length of the posts and the finished height you want the Pergola to be, but the general rule of thumb is that the holes should be at least 30cm deep. The holes should be laid out as 3 at the back and 2 at the front, to provide a solid structural base using the 5 fence posts.


Then it’s time to place the posts in to the holes and secure them with the concrete, ensuring that you check that the posts are straight using a spirit level to maintain the structural integrity of the finished Pergola. Finally, use a piece of wood or string to square off the posts to make sure they are all lined up with each other.


Secure The Outside Frame

Once the concrete has set, it’s time to get to work on the frame. Cut the timber to size to fit with the fence posts, then use the clamps to temporarily secure them to the posts.

Take the long timber screws and fix the frame to the posts, then remove the clamps.

Bear in mind, this method involves not having a post in the middle of the Pergola, so to compensate for this, we suggest doubling up on the framework to provide extra strength.


Adding The Rafters

Now it’s time to add the rafters, it is suggested that you work out the number of rafters you want/need ahead of time, so know exactly how much wood you’ll need before you start construction.

Your choice of rafters is down to you, providing they have the practical and structural benefits required. The most popular choices for securing rafters include overlapping them and securing them with bolts or flush then securing them with mini joist hangers. For extra security, you can add corner brackets to the framework.


Finishing Touches

To finish of the Pergola, using the Dust-Free Sander, go over all of the framework to smooth out any rough edges for a cleaner finish. Then add decorative touches to suit your personal taste.


There are so many ways a Pergola can be personalised to suit your practical and aesthetic needs, from Patio Heaters to a range of lighting, and here at ElectricalDirect, we stock a range of high-quality products to make the job quick and easy with a finish that anyone would be proud of!

Wrapping some Festoon Lights around the rafters and framework of the Pergola will provide a subtle but effective lighting solution, creating ambiance and a beautifully illuminated outdoor space.

To make sure anyone can make use of the Pergola whatever the weather, investing in a top-quality Patio Heater will ensure a cosy atmosphere in every season. Whether it be standalone or wall-mounted, we have the right product for any Pergola project.
