Different blog layout on Home page

Hi

I have my blog working fine using the template provided (with some slight editing) but I want to display a list of blog posts on my home page but I do not want it to follow the same style as my main blog list page. For example I want the image to be to the side of my text, use a different heading style for the post name etc... Basically a different template but I am unsure how to target a specific template for different pages when it comes to using the blog app.

Regards Andrew
