This small apartment in Barcelona, redesigned by its owners Monica Potvin and Markel Otaola, uses an interesting approach to space-saving. Instead of creating a separate bathroom, laundry room and kitchen, they built a cube in the center of their home to house all of the utilitarian stuff. Even the floor space under the hallways around the cube is used for extra storage; this was inspired by the tuck-away elements on sailboats (Markel is a sailor). Watch the beautiful home tour, shot by Fair Companies, to get Monica’s take on living small and a lot of great space-saving ideas.
