Mar House is a minimal home located in Barcelona, Spain, designed by Francesc Rifé Studio. The ground floor, which includes the living, dining room, and kitchen, faces south to bring nature into the living spaces. The first floor, arranged in a U-shape, houses four bedrooms to optimize space. The basement, containing a garage, versatile game room, and guest room, extends northward, offering a secluded terrace for added privacy. Material choice is integral to the project’s aesthetic and function. Externally, white concrete and Canadian cedar wood combine to give the structure both strength and warmth. Internally, dark-stained oak creates a sense of intimacy within the spacious rooms. The terrace acts as a natural extension of the interior, where the kitchen area flows outward, forming a transitional space between the house and surrounding vegetation. Strategically placed for optimal sunlight, the pool area serves as the architectural highlight. Large windows are meticulously incorporated into the design, organizing the building’s vertical lines.
