Architect. Doctor of urban lighting. Designer of the city at night.

Diana Delnegro is an architect and lighting designer, founder and managing director of the studio. She holds a PhD in urban lighting from The Bartlett, University College London, was responsible for the lighting of Lisbon's monuments for over fifteen years, from Praça do Comércio to the Marquês de Pombal, and coordinated the city's first urban lighting masterplan.

She is the author of a book and academic publications on urban and heritage lighting, was a guest lecturer on the Light and Lighting master's at The Bartlett between 2010 and 2016, and chairs the CIE international technical committee TC 4-59, creating the international guide for lighting urban elements. Every project of the studio grows from that ground: rigour, evidence and scientific knowledge.

In practice since 2003 and with a studio of her own since 2016, she works from Lisbon across Portugal and abroad on heritage and historic monuments, museums and exhibitions, hotels and restaurants, public space and urban lighting masterplans, and brings to the heritage work a master's in the conservation of the built heritage from the Instituto Superior Técnico.
