Rising housing and energy costs, the emergence of the non-traditional small household and an increase in the number of seniors have contributed to a renewed interest in adaptable dwellings. These designs can be defined as units or furnishings that permit change of space or function at any time. With their popularity rising rapidly around the world, people are becoming aware of the environmental and budgetary implications of owning a very large single-family home, especially when some spaces in these homes are hardly ever used. Notable additional advantages of adaptable homes are lower property taxes and construction costs, and time savings through possible prefabrication. To be efficient, adaptable dwellings must be carefully designed since minor decisions can have a large impact on their use. Light, boundaries, circulation, choice of materials and furnishings are some of the tools that can be used by designers to resolve challenges and expand spatial perception. Therefore, a good adapt- able design should not only be versatile and efficient but also avoid simplicity and dullness.

Japanese architects, such as Shigeru Ban, have pioneered solutions to these problems by using curtains or shutters to separate between outdoors and indoors. Such fixtures can be opened during the day to let in light and fresh air but can be closed at night. Those designers also encourage the inhabitants to engage with the outside by creating large, easily accessible rooftop spaces that can used for outdoor seating, for example. When partitions must be installed, transparent ones are recommended since they still permit the dispersal of light. Moveable partitions, or sliding panels, are also useful in defining spaces since they allow one to temporarily redefine small spaces according to need. Lastly, an open floor concept with large exterior openings permit views of the outside which, as noted above, can increase the perception of a house’s size. Increasing the floor height can greatly expand space without enlarging the floor area.
