Most of your code looks OK. But there is a major problem with your WP_Query in portfolio template. Your query looks like this:

<?php   $query = new WP_Query( array( 'slug' => 'design' ) );?>

And if you take a look at WP_Query docs, you'll see there is no parameter called slug. So it's pretty clear that it can't work.

If you want to display portfolio posts with given type, then your query should look like this:

$query = new WP_Query( array(
    'post_type' => 'portfolio',
    'posts_per_page' => -1,
    'tax_query' => array(
        array( 'taxonomy' => 'type', 'field' => 'slug', 'terms' => 'design' ),
    ),
) );
