One of the benefits of an all-masonry fireplace is that it can be custom-built to meet the needs and desires of its owner. Most of the time, however, masonry fireplaces also cost more than the prefabricated, zero-clearance fireplaces that are their strongest competition. A number of fireplace designers and builders have been working toward the goal of producing masonry fireplaces that can compete with prefab units on the basis of price as well as clearly beating them on the basis of durability and value. These innovators have found various ways to reduce the cost of all- masonry fireplaces, but most share certain characteristics: simplified design; fewer components; and a package or kit approach.
