Besides designing layout of a building, an architect like me supposed to be thinking about choosing and designing interior elements of every room in the house. This work sometime needs me to be a little bit tricky, creative and innovative as well. How to make signs and tells people about certain things, defining certain area whether it is public, private or service, without using signboards. At least if you need to use signs like exit signs, use them as least as you can. Able to communicate them by using architectural language, and you have more points.
