Fire Place Construction and Layout

A fireplace is a chamber, made of different materials usually constructed to contain the fire for various applications. A fireplace is often known as a hearth. Fireplaces can be made of bricks, steel, stone, and concrete. Fireplaces serve as room heaters for cold areas and vary in design and heat efficiency.
