The concept of Flex Space is demonstrated by two automated wall cartridges that reposition to adjust to three program spaces throughout the day. The home transforms to an office by day, expanded living room at dusk and an full bedroom by night. The purpose of this feature is to allow for maximum usage of a smaller footprint house - resulting in lower energy costs and efficient use of valuable real estate. Power is distributed to these walls through a Direct Current (DC) powered rail allowing for less energy usage and simple energy distribution for the moving walls. The rotating AV wall TV screen allows the user to share the television and audio visual technology between the living room or home office modes thereby reinforcing the concept of flex space and by sharing AV equipment.
