This is the error I'm getting: Uncaught Error: Cannot use object of type House as array in index.php:13

Appreciate help.

index.php 
<?php

// add code below this comment

class Subdivision {

  public $houses = array();

  public function filterHouseColor($color)
  {
    $filteredHouses = array();
    foreach($this->houses as $house){
    if($house["wall_color"] == $color || $house["roof_color"] == $color){
      $filteredHouses[] = $house[$color];
    }
    }
    return $filteredHouses;
  }

}

?>

I have pasted it with syntax highlighting for your convenience:

<?php

// add code below this comment
class Subdivision
{
  public $houses = [];
  public $arr = [];

  public function filterHouseColor($color)
  {
    foreach($this->houses as $house){
      if($house->roof_color == $color OR $house->wall_color == $color){
        $this->arr[] = $house;
      }
    }
    return $this->arr;
  }
}
?>
