Urban design is for all people!

This is key in our designs. The new assignment should lead to an improvement of the environment for all of us. The current existing situation is always our starting point. By analyzing the location, all qualities of the area emerge and this is the base for the future. Public space is one of the most important things in the design; it creates the possibility to connect the existing network of green, outdoor space and infrastructure. By making a good design and ‘ambiance’, the surroundings too will take advantage of the new developments.

A project is successful when all parties are pleased. We take pride in what we have accomplished and we'll continue to focus on the liveability of the city and the living environment of the people.


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.


At Urbis, sustainability starts with a vision on the assignment on the highest scale. By designing a framework of public spaces, an understandable structure arises. This keeps the plan in the long term readable and clear. During the last years, Urbis acquired and practiced much knowledge about the relation between urban design and environmental contours.


In the past years, Urbis dealt a lot with the relation between living, working and the water. Inspired by the current water task, we studied a lot on new concepts in this field. Facing the increasing problems dealing with water and the climate change in the long term, Urbis is determined to carry out these concepts in the urban planning.
