Located in downtown Tokyo, Japan is the Mejiro House designed by architectural firm MDS. Designed to block unwanted views from the street, this cast concrete residence appears as a monolithic block from the outside, but inside is a different story. A light-filled, airy interior stands in stark contrast to the bare exterior and offers its residents a welcome respite from the hustle and bustle of life in the Japanese metropolis. Concealed within is a double-storey courtyard which leads into the interior portions of the residence through a massive glass wall. Featuring a color palette of mostly greys, blacks, and whites and utilizing a mix of cement, wood and stone for the building materials, this monochromatic house’s interior manages to exude warmth in spite of its cool colors and materials.
