Two types of spaces
The problematic task of the relation between empty and filled spaces allows looking at the other objective of the modern construction - transformability - from a new angle. We can imagine our houses not as buildings, or structures supposed to be a retreat, but as an empty space which is available to be filled by a different functions and zones, related to the current life period of a person, or a family. All available space is a home, but we can use only a necessary part of it when it is required. This approach gives us the opportunity to keep house in a balanced condition with all spaces effectively used in terms of energy and economy, meanwhile convenient and comfortable for living.
