If you are going to use the same layout over and over again it is a good idea to create a page template.
Click on create page, edit it as required then save, then click on more actions > save as page template.
Enter a name for your template, description and you can even upload an icon if you like > save
The template will then open for editing, save it > click on view template listing > then click on return to site to get back to edit mode.
To see how to use the template see the article.
Good luck, B
