Krite.

You need to take a Prestashop Theme which is close to what you want to achieve and copy and paste it in your THEME folder.
Give it a new name.

Select this new theme in your Prestashop admin panel.

Then, you need to go in the CSS file (global) to change the design and you can also move things around in the TPL files.
Avoid touching the php files or the site might not work properly, but it all depends of your knowledges.
