What is best practice for 'One Page Layouts'?

I’m in the technical planning stages of a project which i intend to implement a ‘One Page Layout’ on.

I’ve setup the pages ‘people’, ‘clients’, ‘contact’, ‘case studies’ etc and taken the content into my Front Page template using the get_page() function, feeding it the page IDs. This works OK.

I’m intending to have the top navigation menu items, when selected, navigate down the page to there respective section and update the url accordingly.

e.g – Select on ‘people’ (scrolls down page to ‘people’ section), url updates to example.com/people

however, the url will conflict, since the ‘people’ content is setup as a page. And the end-user will be taken away from the front page.

Is there best practice to avoid this?

Thanks in advance, Cam
