Determine the size of the chimney. Size must match the surroundings. Consider whether you want the fireplace to be the center point of the backyard or a complement to an already impressive view.
Try to design the chimney with proportions in mind. It is not recommended that the fireplace completely opacity the size of the house or be reduced by the size of the house.
Choose between firewood or gas. What kind of fireplace is best for you? Many outside fireplaces are either wood or gas. Each method offers advantages and disadvantages:
A wood-burning fireplace provides a natural view and emits a smell that gas fireplaces cannot match. A traditional fireplace also produces a significant amount of smoke, so you must have an exhaust built to strict specifications.
The most important consideration when constructing a gas fireplace is to connect the fireplace to an existing gas line. Gas fireplaces offer many advantages over wood-burning stoves: they do not produce ashes or embers, they do not need an exhaust and rarely require building permits. However, they do not burn so much and lack the rustic charm of a wood-burning unit.
If you are going to build a wood burning fireplace, get a building permit. Most firewood units require permits. Contact the municipal government about restrictions and other requirements. You can begin construction after obtaining the building permit.
The city must inspect the chimney before it can be used.
Find the gas line if you want a gas fireplace. The gas company can help you locate the line closest to the fireplace location.
