Majestic high-quality greenhouse
Kathedral breathes the atmosphere of the monumental churches of yesteryear. With its elegant skylight, the ridge of this greenhouse towers 3.70 meters into the air. Thanks to the roof pitch of 25 degrees, you also experience a comfortable height inside. This makes Kathedral perfect for an orangery, with exotic vegetables and trees as ideal eye-catchers.
