The living room has windows that are 34" from the room corner. I would like to have a stacked rock fireplace with a mantel. Is there a gas insert that would fit and look proportional? Would it be better to have a free- standing small gas wood stove and, if so, have you ever seen a free- standing wood stove built in so that it looks more like a traditional fireplace? House style: bungalow/contemporary farm house. Help! Carol.
