A house is an asset. As the choice of every member of a family is different so, how the design of every door of every house can be same! Culture, behaviour and tradition of a family is different from others. If we think a family as a ground of a drama then we found that there is no similarity between them. When we take a book in our hand then we firstly see the cover of the book. Similarly, when we enter into a house then the door is viewed at first. Interior view of a house is also different from that of other houses. So, door should be different to represent the family.
