The municipality of Venlo commissioned Kraaijvanger to design its new stadskantoor (council offices). With 630 flexible workplaces and public functions, the building embodies the ambition to have the entire city and region function on the basis of Cradle to Cradle (C2C) principles.
Wellbeing is the starting point: a good building makes people happier and boosts productivity. The spatial design is based on three goals:
- to bring as much daylight and greenery into the interior as possible,
- to create routes through the building that stimulate people to move around,
- encounter others, and to use only healthy materials.
The design includes an organic kitchen with a restaurant situated at the heart of the tower. Along with the spiral staircase system in the atrium, this encourages the use of the stairs. The parking garage with its green voids and building cooling system is the foundation on which the meeting functions are organized from the street level upward.
Around a patio with a helophyte filter for water purification, people can enjoy the greenery, the water and the views. A political café, a public hall with exhibition spaces, a wedding room, meeting and consultation rooms, a coffee bar, a theatre with stand, a city shop and the service functions are all located on the first two floors.
Based on the open-house concept, which allows everyone to come and work in this part of the complex, the building connects people and staff. The offices are located on the floors above, in a secure zone in the tower. The complex comprises a single three-dimensional work environment: everything is connected to everything.
The building refers to the agricultural tradition of this Limburg city and its top floor features a greenhouse with seasonal workplaces and room to grow regional products that also heats and humidifies the air that enters the building.
The green air-purifying façade is the largest green building façade in the world and forms a protective shell against traffic and railway pollution. The glass window in the green façade offers a view into the heart of the building – the interior is visible from the inner city, in keeping with the transparency of democracy.
The realization of the new stadskantoor presented an extraordinary opportunity to utilize C2C and circular ideas in a public building of considerable size – and thus to help spread these ideas. During this process, Kraaijvanger devoted a considerable part of its resources to sharing knowledge with partners and stakeholders in order to break new ground. Introducing a system of material passports made it possible to continue to innovate during construction. The passport records exactly what goes into the building. The contractor and producers are challenged to come up with innovative new products that are better than those described in the specifications. The ultimate target is to give the precious raw materials used in the building a new life without compromising on quality.
The building purifies air through the ‘green lung’ façade, recycles rainwater and waste water, is energy neutral and promotes wellbeing. In addition, the building produces no waste: it is in fact a temporary raw materials bank with guaranteed residual values for a number of products. The building’s green façade creates (bio)diversity: like a vertical city park, it is a natural biotope for more than 100 plants, animals and insect species.
The base includes functions that create added value for the entire city, such as a café with theatre facilities, open workspaces on the ground and first floor, and a beautiful garden with helophyte filters. During this project, numerous producers and suppliers acquired C2C certifications for their products and the project thus demonstrably stimulates the transition to the economically profitable principle of the C2C production of goods. The design has won several architectural awards, including the ambitious international Architizer + Award in the category government buildings.

The air in Venlo’s new city hall is purer than the air outside and purifies air in a 500m radius around the building. Cradle to cradle principles and holistic thinking in action in a city's buildings.
