In the Parisian district of Montmartre, local design firm SABO Project does exactly that with this attractive remodel of a fashion designer's top-floor apartment, bringing in a multifunctional wall that acts as an all-in-one storage cabinet, sliding wall and unique set of stairs. © SABO Project Seen over at ArchDaily and cheekily called "Hike," the firm's design for the 775-square-foot residence opens it up considerably by removing some existing partitions. The multifunctional wall is an intervention that can be used as an office, closet, and hides a sliding wall that provides access to the kitchen, bathroom and one of the sleeping areas, on the lower floor. We love the stairs -- definitely worthy enough to be our Stair Of The Week -- and apparently inspired by the 436-foot hill that Montmartre is famous for, and the "local climbing culture" that surrounds it. © SABO Project © SABO Project The modernist kitchen's anemic look is offset with a series of rainbow-coloured natural rubber flooring strips, as well as a wall of integrated, vertical planters that allow the client to grow some fresh herbs at home. © SABO Project Tucked under the apex of the building's roof, the lofted sleeping area features a bed placed under a skylight. The project's white surfaces -- used to reflect and augment the available daylight -- are offset by choice punctuations of colour and exposed beams of wood. There's no photos of the bathroom, but judging from the plans, it appears to be a nice, double-height space with translucent windowing at the top, to let more light in. © SABO Project In the bedroom on the lower level, there's yet another full-height wall of storage to free up more floor space. © SABO Project © SABO Project © SABO Project Vibrant and quirky, this is yet another project that cleverly increases functionality in tight, urban quarters by adding a multifunctional, "transformer" element into the mix.
