This fireplace is an exact copy of the original Douglas fireplace design. However, there are added features including a flared two-stage mantel and a matching flared top. This design is a corner unit and it is a very large structure. This design has raised extensions on both sides and plenty of seating space is available for many to sit around the fire. The front seating is 16" deep. To the sides of the chimney, there are 16" mantel shelves, which are big enough for candles or other decoration and adornment. The overall dimensions of this fireplace are 175" wide, 72" deep, and 80" high. The firebox opening measures 32" wide, 24" deep, and 24" high. This fireplace requires block cutting.
