Then following are the steps demonstrate how to create a new block region in Drupal 7.
Step 1:
Open up your theme’s .info file and add the following line:
regions[new_region] = New Region
Step 2:
Now go to the your site url/admin/structure/block and select which block you want to show in your newly create region, and save the your choice.
Step 3:
Then you’ll need to print out your new region in your page.tpl.php file which goes something like this now:
<?php if ($page[‘new_region’]): ?>
<div id=”new_region”><div>
<?php print render($page[‘new_region’]); ?>
</div></div>
<?php endif; ?>
