The typical fireplace requires a base (usually a concrete slab), firebox and a chimney or vents. Once you've nailed down those boring bits, survey your budget and decide if you have enough wiggle room to add a few fun extras! For example, consider making your fireplace a multi-functional entertaining mecca by including a built-in grill, sink or bar. Permanent bench seating with removable cushions can give your guests extra space to relax, or you can dress up the area with potted plants or other outdoor décor. Wood storage is another logical extra that will make starting a wood fire much less labor intensive.
