Not sure if it's the best way to do this, but you can tryuse the following forcode, with Drupal 7::.
function MODULENAME_preprocess_views_view(&$vars) {
if ($vars['view']->name == 'VIEWNAME') {
$vars['rows'] = "<div class='wrapper-class'>" . $vars['rows'] . "</div>";
}
}
This will wrap contents just below the "view-content" class
