The Mutual Building in Porto reimagines a historic office landmark into a sustainable, future-ready workspace. With a dynamic façade responsive to solar exposure, a welcoming double-height lobby, and panoramic rooftop views, the design blends innovation with heritage. Outdoor terraces, energy-efficient systems, and human-scale interiors create a vibrant, flexible environment—where legacy meets vision in a new benchmark for commercial architecture.
