Outdoor Fireplace Design

Haugen/Zohar Architects designed an outdoor fireplace for a storytelling at a children's school in Trondheim, Norway that I've thought about quite a bit, since coming across a photo a few years ago. It would be a lovely addition to my dream Ayurvedic Spa. Surprisingly, it's very difficult for the wooden structure to catch fire, according to the architects. More below the pictures. Thank you to Dave from Contemporist Design for making these pictures and the explanation below available.
