The close interior approach to space planning creates several isolated rooms that serve specific purposes. For example, the isolated rooms like living rooms or bedrooms are designed to serve a specific purpose, and they are not supposed to be used for any other purpose. This close interior approach highlights the importance of individual privacy of prospective dwellers. On the other hand, the open interior approach considers the individual as the part of the society, highlighting the importance of caring and sharing. The social and business interests dominate over the privacy requirements, and interior space is designed to optimize the active, dynamic and communicative lifestyle of the prospective dwellers. The space is still divided into rooms, but they don’t create any functional division of the living space. This open interior approach proves very instrumental in designing modern house structures that require more flexible or visible house planning. The open interior approach is not a new phenomenon in house planning. The architects realized the importance of creating enfilade of adjacent rooms before two centuries ago.
