Thanks! The space is about 21 feet wide and 42 feet in length, with the kitchen at one end and the living room/fireplace at the other end. The long window wall on the right side of the photo is south-facing, and the fireplace is on the east wall. The fireplace itself is a wood burning insert.

Thank you very much

I keep returning to this image as we plan a passive solar. Wonderful space. What brand is the fireplace insert, please?

Another question, please. What is the brand of the wood burning insert? Many thanks
