The Traditional Hearth

• Decide what type of fireplace you like. A traditional hearth will have a chimney flue just like its interior cousin and because of the size and height of a chimney, the outdoor fireplace architecturally defines the boundaries of outdoor living because we are conditioned to associate it with a building, according to Jane Gitlin in her book, "Fire Places."
  These fireplaces can be made from brick, stone or metal, and if you plan on building this type, decide on a location first and building material second. Manufacturers offer prefabricated units which are worth investigating before any decisions are made. Depending on your level of construction expertise, a prefabricated unit may be the answer.
  
  

Combination Units and Fire Pit

• The combination fireplace and stove/oven is the perfect option for someone who likes to barbecue or enjoys the taste of a fire-baked pizza. These units have a smaller opening than a traditional fireplace and have grates that can be removed after cooking is completed. Fire pits can be built into patios and decks and are, by definition, chimney-less, open-sided fireproof containers, either constructed of metal, brick or concrete. Fire pits can be either decorative or can be used as grills.
  
  

Installation Basics

• Before you begin any project, check to see if you need a permit to build and what the relevant codes are and then begin the planning stage. If you decide to build your own fireplace or combination unit, remember that stone is heavy and requires a firm foundation on which to build. Consequently, the ground needs to be level and graded before stone is laid.
  Other considerations include whether or not the fireplace will be a gas or log burning model. If it will be run on gas, then gas lines will have to be laid. If it will burn wood, then you will need a supply of wood.
