I recently found this video interview with the owner-design-builder team of this unusual house in my neighborhood.
In the video, they reveal the source of many of the materials and their inspirations and technical considerations.
For example, they used lighter colored car roofs for siding on the north side to reflect more indirect sunlight into the house to the north. I’d love to see how this worked out. It might reflect a bit too much in the summer when the sun actually rises and sets in the North part of the sky….but other times it’s probably quite nice.
