Welcome to the Bunnings Workshop community. It's fabulous to have you join us, and thank you for sharing your question about paving.
Putting pavers in your home is a great way to improve accessibility and add an extra feature to your home. I suggest having a look at this guide - How to lay paving for a path by @Adam_W. Some of the things you'll need to consider are the size of pavers you'll be using, the actual size of the pathway you wish to make, and how long will the pathway be.
I suggest making a simple diagram with pen and paper, you'll then be able to calculate the amount of sand, gravel and pavers you'll need to build your pathway.
