How can I create a new custom page with my own content in Elgg

I would like to create a new page in Elgg where I can put my own content. I would like to have there all the default menus, etc. but with empty space where I can put my code. I would like to have a link to this page on my profile page. Should it be done as a new plugin? If yes, how to create empty page with my current template settings?
