Spanish firm PKMN Architectures (previously) has created yet another brilliant design with moveable walls, allowing this mature couple in Asturias, Spain, to transform and adapt their space to their ever-changing needs, like accommodating visiting relatives. See it in action: © PKMN Architectures Dubbed Casa MJE and one of the firm's series of Pequeñas Grandes Casas ("little big houses"), the 753-square-foot design features two rotating walls full of storage cabinets and hideaway beds that can be tucked away when not in use. But when family comes to visit, these walls on wheels can be easily rolled into place to form up to two extra bedrooms. © PKMN Architectures © PKMN Architectures © PKMN Architectures The apartment is a second home for Maria Jose and Enrique, who are based mostly in Mexico but travel to Spain often. They wanted to be able to welcome their grown children and their grandkids right here in this apartment. The design allows them to adapt the space according to who's staying there; they can have one big open space, or, at the push of the hand, have one bedroom for themselves, or two, each with sliding doors to close it off -- all in no time flat. © PKMN Architectures © PKMN Architectures © PKMN Architectures These images give you an idea of what's possible with these two rotating elements that can either open up or close off the space. © PKMN Architectures © PKMN Architectures The flexibility of this design and other similar schemes are a great way to expand what could have been a statically partitioned space, which would have locked its occupants into fixed patterns of use and movement -- ultimately making a small home feel even smaller. With this ever-adaptable design that can expand the space, many more options for functionality and enjoyment are made possible. Check out more over at PKMN Architectures.
