Usually, we do not give much consideration to light – a big mistake according to Swiss architect and lightning designer Reto Marty. His lightning design firm Nachtaktiv in Zurich specialises in customised architectural lighting solutions and is an expert in achieving a sophisticated dialogue between light and space. Marty founded Nachtaktiv in 2005 and today, his experience covers cultural, hospitality, retail and office schemes as well as residential and infrastructure developments. His work showcases how light can take on a multitude of roles in architecture and built environments; the projects represent architectural lightning at the very top of its game.
