The G12 House by (se)arch Freie Architekten is situated in Germany, and is a house that makes the most of natural lighting. Instead of closing the interior off from the natural sunlight, the architects have made opening the house up to the outside a main priority. The house features floor-to-ceiling windows on the top floor, allowing residences to completely open these up on a hot summer's day.
Considering the difference that access to natural light has on one's mood, having a place such as the G12 House would also be good for your health. When one is exposed to too much artificial lighting, this can disrupt the circadian clock, and lead to sleeping problems and other health issues.
