Style favourites list

I want to change the layout of the favourites list from the standard list output to a more styled one (with divs etc).

Does anyone know how I can achieve this?

I know the code section I want to use for the new look:

<div class="grid-50 mobile-grid-100 propertybox">
                    <div class="featuredimage">
                        <a href="<?php echo get_permalink( $item->post_id );?>">
                            <?php echo get_the_post_thumbnail( $item->post_id, 'full' ); ?>
                        </a>
                    </div><!-- end featuredimage -->
                    <div class="grid-30">
                        <h4 class="pink price-page">
                            <?php the_ccyamt(get_field('property_price', $item->post_id)); ?>
                        </h4>
                        <br>
                        <?php the_field('details', $item->post_id); ?>
                        <br>
                        <br>
                        <p>REFERENCE: <?php the_field('reference_number', $item->post_id); ?></p>
                    </div><!-- end grid-30 -->
                    <div class="grid-70">
                        <h2 class="categorytitle">
                            <a href="<?php echo get_permalink( $item->post_id );?>">
                                <?php echo get_the_title( $item->post_id ); ?>
                            </a>
                        </h2>

                        <?php
                        //the_content();

                        $my_postid = $item->post_id;
                        $content_post = get_post($my_postid);
                        $content = $content_post->post_content;
                        $content = apply_filters('the_content', $content);
                        $content = str_replace(']]>', ']]>', $content);
                        echo $content;

                        ?>

                        <a href="<?php echo get_permalink( $item->post_id ); ?>" class="button floatright">
                            More Details
                        </a>
                    </div>
                </div>

and I know it needs to go in somewhere around here:

private function setList()
	{
		$favorites = get_user_favorites($this->data['user_id']);
		$out = "";
		foreach($favorites as $favorite){
			$out .= '<li>';
			if ( $this->data['links'] ) $out .= '<a href="' . get_permalink($favorite) . '">';
			$out .= get_the_title($favorite);
			if ( $this->data['links'] ) $out .= '</a>';
			$out .= '</li>';
			echo 'Text goes here'
		}
		$this->list = $out;
	}

on the FavoritesListHandler.php file.

Can anyone help me?
