Cellar doors serve two purposes.  First is the barrier to maintaining the cellar environment we are looking to protect.  Essentially we are installing an exterior type door to this interior space.  One that keeps the cool air in and the warm air out.  Second is the asthetics that provide the invitation to explore whats behind the door.  Is the style you pick commensurate with the interior design of the room and/or does it compliment the exterior space outside the room.  Pick the one that is right for you.  If you are looking for something different we can build it.
