Casa M60 is a minimal residence located in Madrid, Spain, designed by estudio DIIR. The architecture of Casa M60 is notable for its straightforward approach that emphasizes the length of the building. Rooms are arranged in a sequence that enhances the space’s linear quality while subtly dividing it. The division is achieved through a series of walls that not only separate spaces but also include openings that connect one room to the next, creating a fluid transition throughout the home. This layout introduces a rhythmic flow that seems to extend infinitely, thanks to the symmetrical placement and proportions of these openings. Each space within Casa M60 is designed as an independent unit, complete with bespoke furniture that integrates seamlessly with the overall design concept. This integration allows the central areas to remain open and versatile, supporting a range of activities without the clutter of traditional furnishings. The design’s simplicity is complemented by a carefully selected color palette and materials. The use of light, understated materials provides a tranquil backdrop, while strategic accents, such as granite frames around openings and reflective surfaces on certain pieces of furniture, create visual interest and contrast, adding depth and character to the spaces.
