How it works

There are 4 different options to choose from when ordering your Pergola. Our basic 9ft x 9ft standard ‘building block’ system is designed to be extendable in a simple and easy way, proving that you do not need to be a construction engineer to install one!

The following sizes are available:

Option 1: Standard - 2700mm x 2700mm (@ 9ft x 9ft )
Option 2: Standard - 2700mm x 4860mm (@ 9ft x 16ft )
Option 3: Standard - 2700mm x 7020mm (@ 9ft x 23ft )

All our pergolas have a standard width of 9ft (2700mm) but with the option of incremental increases in length. We decided to keep to the 9ft (2700mm) width as our pergolas are designed as a ‘lean-to’ system and this width allows a quick and easy installation in most locations giving enough room in which to entertain, live in and customize to your own specification whilst keeping the costs down. To assemble any of the longer pergolas simply repeat the assembly instructions for each of the modular ‘building blocks’ – it couldn’t be easier!

Option 4: Customise the length to your own requirements

Due to the differences in heights (particularly in old buildings) of windows, doors and sills etc - we have built in added flexibility to the post lengths to give you the choice when our standard 2.4mtr length is not enough. Therefore, at no extra cost, you can specify post lengths from between 2.4mtrs (approx: 7ft 8ins) to 2.7mtrs (approx: 8ft 8ins) inclusive to meet your requirements. If you would like to take up this service, please email us at info@perfectpergolas.co.uk when you order your pergola and we will pass on your instructions to our Mill.

If you require a custom made pergola, please visit our Pergola Planner facility accessed via the Homepage *NB - when designing your pergola or arbour, care must be taken to ensure that the the gap between the posts is no more then 3500mm for the 24hr high pressure treated timber and 4000mm for oak.

Most of the measurements detailed in the following assembly drawings (Steps 1 - 8) are metric – however, if you prefer to work in good old 'feet & inches', please find below a simple conversion table allowing you to chose whatever system you find easiest:

Modules Parts List:

Please see below a drawing that shows all the constituent items that are needed in order to successfully build your pergola. Once you have chosen the length of pergola you require, just tick the option on our ordering page and leave the rest to us. All of the necessary components will be automatically calculated and added to your order – making it easier for you to concentrate on just the assembly.

The photograph below shows all of the hardware we will supply (depending on which module you purchase) in order to assemble the pergola in a safe and secure manner. Some of the parts are purely representative as occasionally different manufacturer’s components may be used if sourcing becomes difficult or is delayed in any way.

Once you have received your delivery, please carefully check that all items have been included against the packing list supplied and, once done, you’re ready to start to assemble your own pergola. Please follow these simple steps as a guideline to ensure that the assembly of your pergola is as trouble free as possible:

*NB – By using wood as the main material in the construction of a pergola, its very nature means you may find that it expands or contracts slightly depending on conditions. For example, if you experience difficulty in inserting a 100mm x 100mm post into the Fixing Post support - it may be because the wood has expanded a little. If this is the case, just take some coarse sandpaper and sand the bottom outside faces and edges that will be inserted into the support. Not too much though and it’s worth checking about every 30 seconds of sanding as to whether it will fit snuggly into the metal support. If not, continue to gently sand and check often!
