The lexical meaning of housing is a building that protects menfrom natural harms such as rain, wind, cold and heat andsocial harms such as theft and destruction. It is not anover-statement to say that human history had begun together withhousing. Men cannot live without housing.　　Being faithful to basic is always the most important. Therefore,I believe it is quite meaningful to collect the housing of theworld, which is the foundation of architecture and the essence ofliving, and introduce them tothe readers.　　The five Olympic rings which symbolize five continents are themotif of this. book. In the Olympic rings, the blue, yellow, black,green and red rings from left are overlapped in W-shape. Likewise,this book introduces the multi- family housing recently completedin Europe, America, Oceania and Asia. The concept of family is alsochanging now and this book tries to suggest the future direction ofhousing by showing the rapidly changing concepts on housing andresidence by way of showing recently completed architecturalworks.　　I sincerely hope that %HOUSING will become one of the bases inlearning the housing trend in Korea and overseas to the readers. Itwou{d be my pleasure if readers would get useful information andwise insight from this book.　　As last, I would like to express my sincere appreciation to thearchitects and owners who helped us with information andphotographing opportunities. I promise that the Archiworld willcontinue to provide dear readers with solid contents and greatediting. Meanwhile, your continuous interest and support would behighly appreciated.
