Urbis has been 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 a partner in Urbis. Since then, Donald Lambert and Petra Sala are the managers of Urbis.
