Don't make rooms too deep
Bring more sunshine into your house: part 5
A big ruiner of sunlight access is the sheer depth of the rooms we build. The proportions of a room with regards to the natural light source can cause a room to be one half blindingly lit and hot and the other half pitch dark. That's because contrast in light exposure changes the way we see things. Too much light in one room can cause you to not see anything when you enter a less-lit one, like when you come inside a dark room after having been out in the sun.
