You need them to be

HI,
Thanks for that idea, in fact I have that working fine.
The example I gave was maybe too basic, I have singlepage/controller pair working very well, its when the user visits the folder
single_pages/admin/company
How do I get a default view to load for that url, in this case maybe some basic company info. In previous versions I would drop in a view/controller pair and all would be good, in 5.8 it isnt working for me.

To take your example if I visit what would I expect to see?

single_pages/admin/company

This is a url, it has other sub urls below it with pages defined.
The default view could simply do a redirect to a page.
In the c5 core look in
/concrete/controllers/single_page and you will see accounts.php this is paired with /concrete/single_pages/accounts/view.php

I have tried to reproduce this in my application folder but it isnt even finding the view.

If you are trying to see something at the URL /admin/company you would put the files at

With all of the valuable suggestions and solutions I came up with this which is working well.

controllers/single_page/admin/company.php
single_pages/admin/company/view.php

so visiting <url>/admin/company

will load the default view.php correctly.
The reasons for wanting to explore this approach include a better understanding of this method but also a precursor to me starting a big project to migrate a C5.6 to C5.8

Thanks for all the advice.
