Siena is a private residence on the Costa Brava conceived to embody Mediterranean calm. The project presents refined luxury interiors and luminous living, opening the traditional house to the landscape to capture sea views and greenery. At MA&partners we shaped a contemporary architectural language with natural materials and a warm palette, enhancing daylight and seamless indoor-outdoor continuity. A generous façade opening reframes the home’s core, orienting daily life toward the horizon and creating fluid, welcoming rooms. The result is a residential project with timeless design, sensory balance and a distinct Mediterranean character.
