Claesson Koivisto Rune’s supremely minimal entry follows the firm’s established clean aesthetic to a tee. The system proposed for this sculptural volume is prefabricated sandwich sections shipped on a flatbed truck and assembled on-site. The simple structure is essentially built with wall and roof planes, sealed with glass, and polished off with the addition of horizontal, flush-fitting, wood paneling painted white. The floor rests on concrete plinths, and the roof is supported by the wall sections and steel columns. CKR’s design is based on two rectilinear U-shaped structures standing back-to-back—one opening to the east and encompassing the bedrooms and bathrooms, the other opening to the west for the office/studio and gym. A hallway running north-south separates the two U structures and acts as the communal area, featuring the entryway, kitchen, dining room, living room, and even an interior herb garden lit by a skylight. The walls of the house are deep, effectively hiding storage such as bookshelves and closets as well as mechanical equipment. The roof is a flat sloping plane, with the higher end rising toward the south, allowing for the most natural light. The roof is a rhomboid, rather than square, the exposed wedges at the east and west ends acting as dramatic outdoor terraces.
