how to make archive template different than blog one

Hi Astra Dev Team,

Thank you very much for the best theme for wordpress ever ??

I have a question:
how to change archive template without affecting the front page: I have homepage with the default template (one column, thumbnail at the top and title and description at the bottom for every entry). I want to change the template for archives to : one column, but thumbnail at left and title and description at right for every post.

I created a new blog-layot.php inside my child-theme \wp-content\themes\mychild-theme\template-parts\blog\blog-layout.php

and added

if( is_home() ){
...default markup 
} else if ( is_archive() ) {
...my markup for archives...
}

But this did not work! wordpress hangs!

The markup I will do it myself. Is there a hook to achieve this ? Any help please ?

Thank you in advance
