But these spaces don't have to feel small; a smarter, space-saving approach to design can help immensely. In Milan, PLANAIR (previously) has designed an impressive solution to a small 317-square-foot (29.5 square metres) apartment: by installing a huge, movable wall that can be rolled in place to be used as a room divider and piece of furniture, or out of the way to make way for the bed or to entertain guests. © PLANAIR © PLANAIRSeen over at Contemporist, the TAAAC! apartment is part of a revitalization of a dockside area near Via Savona, Tortona and Darsena. While the apartment's main lounge area -- which includes the dining area and off to the side, the bathroom -- remains static and open, it's the middle zone of the apartment that gets the transformer wall treatment. © PLANAIR The designers explain their concept: From a formal point of view, the project consists of two types of container cabinets: fixed and mobile. Those fixed rooms have service spaces and functions such as a kitchen counter and a laundry room. These furniture features temporary functions such as the study area and the breakfast / lunch desk, and the walk-in closet. The daylight is divided into three different areas, one with fixed cabinets, one with sliding and tilting cabinets, and one without large items and furnished with movable pieces. When the thick movable wall is positioned in the middle of this space, it can deploy a folding desk out on one side and a folding bar table down on the other side, allowing for two functions at one. The sizable wall itself is full of shelving and storage -- though from the looks of it, it's only supported by regular caster wheels. In entertaining mode, the wall can be pushed all the way to one side, to make more room for guests to mingle and sit at the bar table. © PLANAIR © PLANAIR To get ready for bed, the wall is shifted to other side, and the fold-down bed opened out. © PLANAIR The one question here might be how to access stuff stored on the bar-table side of the big wall, once the bed is also pulled down, but it's otherwise a neat design that expands and makes the most out of what would be an otherwise tiny space.
