Urbis was founded in 1987 by Donald Lambert MSc. Since that time, Urbis worked on a continuous stream of projects, with an emphasis on interventions in the existing city. Nowadays, this is an impressive list with over 500 assignments, varying from low-scale urban projects to large regional visions.
In 1992, Urbis and Kraaijvanger Architecten associated to an office for architecture and urban design, Kraaijvanger • Urbis. After 15 years of intensive cooperation, the complete division urban design continued as an independent company, called Urbis.
In 2008, Petra Sala joined as partner in Urbis. Since then, Donald and Petra are the managers of the Urbis team,consisting of urban designers, draftsmen and landscape designers. Since 2016 we are located in the historical monument of the Heineken Brewery Office in Rotterdam.
