No matter you prefer hosting your guests outdoors or indoors, a fire feature can always create the right ambience for you and your guests to enjoy food, drinks and conversations. The best feeling I have in my mind is that when I was young, on every cool night, my family and neighbours was sitting together next to the small fire pit, talking and laughing, we children were jumping around the fire pit and playing games, just like the holiday time in the wild, enjoying the raging fire, without any pressure with all the troubles gone.
