Now THAT'S a fireplace! Pretty impressive!
In a large room like this, you need something of a grand scale to be the focal point, and this fireplace is perfect! The windows are also a great focal point. A big room can have several focal points, actually.
And with a room this big, it needs big structural pieces like the big beams, interior logs, and large furniture pieces. Larger rooms need larger statement pieces like these to balance out the size of the space.
