I solved it. Maybe it could be a better code. But it works and i’m happy with it. 🙂

<?php 
			$posts = get_posts(array('meta_key'	=> 'haus'));
			if( $posts ) {
				$anzhaus = array();
				foreach( $posts as $post ) {
					setup_postdata( $post );
					$anzhaus[] = get_field('haus'); 
				}; //foreach( $posts as $post )
				$uniquehaus = array_unique($anzhaus);			
				foreach( $uniquehaus as $hpost ) {
					setup_postdata( $hpost );
					echo('<div class="hausbox"><div class="Haustitel">'.$hpost.'</div>');
						$args = array('meta_query'	=> array('relation'		=> 'AND',	array('key'		=> 'geschoss'),	array('value'		=> $hpost)	));
						$the_query = new WP_Query( $args );
						if( $the_query->have_posts() ) {
							$anzgeschoss = array();
							while ( $the_query->have_posts() ) {
								$the_query->the_post();
								$anzgeschoss[] = get_field('geschoss');
							};
							$uniquegeschoss = array_unique($anzgeschoss);
							foreach ($uniquegeschoss as $geschoss) {
							echo'<div class="geschossbox"><div class="Geschosstitel">'.$geschoss.'</div>';																			
								$wohnargs = array('meta_query'	=> array('relation'		=> 'AND',	array('value'		=> $geschoss),	array('value'		=> $hpost)	));																		
								$wohn_query = new WP_Query( $wohnargs );
								if( $wohn_query->have_posts() ) {																						
									while( $wohn_query->have_posts() ) {
										$wohn_query->the_post(); ?>
										<div class="Wohnungsbox"> //here we go!!!
											

									</div>
							<?php };
									}; ?>
								</div>	
							<?php		};
						};
						wp_reset_query();	 // Restore global post data stomped by the_post(). 
					echo('</div>'); //hausbox
				} //foreach( $uniquehaus as $hpost )
			}; //if( $posts )
			wp_reset_query();	 // Restore global post data stomped by the_post().
 		?>

One step further…. this works for the first loop:

<?php 
   $posts = get_posts(array('meta_key'	=> 'Content'));
   if( $posts ) {
      $anzContent = array();
      foreach( $posts as $post ) {
         setup_postdata( $post );
         $anzContent[] = get_field('Content'); 
      }; //foreach( $posts as $post )
      $uniqueContent = array_unique($anzContent);			
      foreach( $uniqueContent as $contentboxes ) {
         setup_postdata( $contentboxes );
         echo('<div class="Contentbox">');
         echo($contentboxes);
         echo('</div>'); //Contentbox
      } //foreach( $uniqueContent as $contentboxes )
   }; //if( $posts )
   wp_reset_query();
?>

To get the Contentboxes i did 2 loops. One loop to get all Content values of all posts (like A,A,B,E,D,D,D).
then I put this array in an array_unique to get each value only once (A,B,E,D)
For each of this array_unique_values i createt a <div>.
This works so far.

Now i tried to get the wraps of each Contentbox the same way:

<?php 
   $posts = get_posts(array('meta_key'	=> 'Content'));
   if( $posts ) {
      $anzContent = array();
      foreach( $posts as $post ) {
         setup_postdata( $post );
         $anzContent[] = get_field('Content'); 
      }; //foreach( $posts as $post )
      $uniqueContent = array_unique($anzContent);			
      foreach( $uniqueContent as $contentboxes ) {
         setup_postdata( $contentboxes );
         echo('<div class="Contentbox">');

            $wraps = get_posts(array('meta_value' => $contentboxes));
            if( $wraps ) {
               $anzwraps = array();
               foreach( $wraps as $wrap ) {
                  setup_postdata( $wrap );
                  $anzwraps[] = get_field('wrap'); 
               }; //foreach( $wraps as $wrap )
               $uniquewrap = array_unique($anzwraps);			
               foreach( $uniquewrap as $thiswrap ) {
                  setup_postdata( $thiswrap );
                  echo('<div>');
                  echo($thiswrap);
                  echo('</div>');
                };
             };		

         echo('</div>');
      };
   };
   wp_reset_query();
?>

This is not working. It echoes the same value each contentbox. Why? I don’t get it… 🙁
