How to build a footing for 3x3 gazebo?

[NishanS]

Hi,

I have purchased 3x3 m gazebo. I want to install it in my back yard. There is a deck at the back. But it is a floating deck. So I’m planning to install the gazebo directly on the ground. Each pole of gazebo comes with base plate which has 4 holes for bolts. Total weight of the gazebo is 164 kg. Can someone please advise me about required dimensions for my concrete footing. Thank you in advance.

Hi @NishanS,

A warm welcome to the Bunnings Workshop community, it is fantastic to have you with us.

You should start by confirming with your local council whether your gazebo requires building approval. While it is a relatively small structure, some councils require engineering drawings to be submitted. It's worth checking now to ensure everything is up to standard before installation.

If your council requires building approval, then the anchoring method would need to be confirmed with the engineering plans to ensure it is a suitable installation.

For a structure of this size, a cylindrical concrete pier in each corner with a diameter of 300mm and a depth of 600mm is common, but it is worth confirming with your local council before proceeding.

Let me know if you have any further questions.

Hi Jacob,

Thank you for your prompt reply. I have already checked with my local council, and it turns out that I do not require a permit since the structure is less than 10 square meters in area. Therefore, I can proceed with your instructions, adding the footing of the specified size.

I will also ensure that there are no utility lines underneath my backyard before digging, and I will contact the relevant parties to confirm this.

Please let me know if there is anything else I need to consider. I truly appreciate your support with this Christmas project.

Hi @NishanS,

I'm glad to hear you can proceed with the installation.

The only other advice I have is to check out the Post Hole Digger which can hired through your local Bunnings' Hire Shop. This will make digging your pier holes a breeze. 

Let me know if you have any other questions.

Thank you for the post hole digger; it will be extremely helpful for the job. At the same time, I would like to get a 300mm diameter Formwork Tube (Formatube) as well. I believe it will make the process of building the piers much easier. I’ve searched for it but wasn’t able to find it. Does Bunnings sell them? If so, could you please provide the details?

Hi @NishanS,

I am not aware of us selling Formatube, or any formwork tube. You might like to speak to the Special Order team at your local store and they'll be able to double-check the suppliers in your area.
