Czech architecture firm Atelier SAD unveiled Port X, a home that can operate independent of a power grid. Port X has a design that makes it possible for it to be installed on the ground like a regular dwelling or float on the water like a houseboat. It comes in several sizes, can be expanded or shrunk to increase or decrease living space as needed, and can operate on or off-grid. The flexible size of the Port X is enabled by its construction from pre-fabricated C-shaped modules.
Port X's interior features wooden floors, walls, ceilings and terraces and the rooms are divided with plasterboard walls. It features built-in cabinets in the hallway and bedrooms and a well-stocked kitchen complete with a refrigerator, washing machine and dishwasher. The windows merge with skylights to offer natural lighting, with electric lighting provided by LED bulbs.
