A corner fireplace door is somewhat smaller than an ordinary fireplace door. They usually come in the traditional accordion-type frame because of the limited space offered by the walls. In choosing a fireplace door from the rack, the purchaser has to ensure that the door is big enough to cover the widest area of the fireplace opening without covering the whole mantle design. The door should overlap the whole fireplace opening in order to serve its purpose, but should not keep the fireplace itself from being seen and admired.
In designing contemporary fireplaces, the project commences with a basic design concept. Then a simple measured image is drawn up, which then is transformed into a life-size representation that permits a more detailed look at the moldings and the carving details so that more minute dimensions can be determined. After all of this information is ascertained, the details are sent to a stone mill, and the materials are ordered (10-ton blocks are commonly ordered as a starter piece, but each project will require something different).
