Can you build the default header (new site), from scratch or do you need code

In Wix Studio, you are given a default header whenever you start a new site.

However I can’t seem to rebuild this header if I don’t go through the ‘new site’ procedure.
Is it possible or is it purposely not doable?

Thanks
