Well, many would agree that a creative design of the house emphasizes your personality, and in some way, helps you feel better. Quite often, people do a huge mistake and pay much attention to the interior leaving the exterior as it is.
Such an approach is totally wrong, as the first thing the visitors see is the exterior, and quite often they may develop a wrong opinion of you from that. Fortunately, there is a number of options to deal with this problem. You can hire a professional designer or even do everything all by yourself. For many centuries, people have been trying to decorate their homes in different ways. Agree that nobody likes to live in a house that looks exactly the same as dozens of others.
