In the future, people may be shielded from weather by electronic means. Newer technologies may make walls transparent so that occupants can view the surrounding landscape without those on the outside being able to see in. Daylight could be softened and subdued according to the preferences of the occupants. Dwellings could provide a barrier to sound, insects, and dust, while also maintaining an optimal internal temperature. The building’s materials may generate energy and control the surrounding climate. The home will be engineered to do its own maintenance. For example, a floor surface could be ceramic without the grout. It will be micro-etched so that moisture or fungus cannot adhere. There would be many sensors throughout the home for optimal cleanliness, interaction with the occupants to meet their needs, and for energy conservation. In some cases, the interior walls and ceiling will be luminescent rather than using any single source of light. Color would change on demand. Speaker systems and other electronic devices could be an inherent part of the structure. The telephone may be invisible and a component part of the interior structure. It may focus sound to the location of your ear. The furnishings may consist of totally different configurations that automatically adjust to our bodies as we move.
