app/View/Layouts/default.ctp:
<meta name="description" content="<?php echo empty($meta_description) ?
'default meta description here' : $meta_description ; ?>" />
and add this to your controllers actions or views:
$meta_description = $house['House']['meta_description'];
$this->set(compact('meta_description'));
