The Shadow House by Michael Jantzen takes the sun into account, and includes it as part of the abode. While this is just a rendering as of now, it shows how the shape of a house can completely change when the sun is hitting it in a certain way.
In the pictures, the architect experiments with how a house shifts in terms of its size and shape as the sun moves throughout the day. According to DesignBoom, "Jantzen uses this phenomenon to create an unexpected space expansion of the original conventional symbolic house form."
While this is just a rendering, it certainly makes viewers think about how its not only materials that make up the look and overall feel of a house, but unexpected elements too.
