Light On Two Sides Of Every Room

We've shortened this title to Light on Two Sides. This is most everyone's favorite pattern and the shortening comes from use.

This pattern, perhaps more than any other single pattern, determines the success or failure of a room. The arrangement of daylight in a room, and the presence of windows on two sides, is fundamental. If you build a room with light on one side only, you can be almost certain that you are wasting your money. People will stay out of that room if they can possibly avoid it. Of course, if all the rooms are lit from one side only, people will have to use them. But we can be fairly sure that they are subtly uncomfortable there, always wishing they weren't there, wanting to leave - just because we are so sure of what people do when they do have the choice.
