Welcome to the Bunnings Workshop community @harry1983. It's great to have you join us, and many thanks for your question about installing a slider door.
When responding to your question, it would be helpful for our members if you could tell them a little more about your project and what you need assistance with. They'll then be able to make helpful and useful suggestions.
Were you looking to install a whole new alfresco sliding door system? If so, the product's manufacturer would provide the installation guide. The modifications to your exterior wall would also very much depend on what size door you choose and if the wall is load-bearing. If modifications are required to the wall, and you aren't sure if it is load-bearing, then I'd suggest you employ the services of a professional, like a structural engineer, to determine if installing that style door system is possible. They'll also be able to tell you what type of structural member needs to be installed as a header to span the gap above the door.
We can order a range of Polar Eco-view sliding doors that you might like to check out.
Please let me know if you have any questions.
Mitchell
