Daring to think outside the box

Pioneers in improvement

We are improving buildings and their environments in the areas of safety, sustainability and comfort. This requires new insights and modern solutions. The same applies to our collaborations. Our collective consists of 5 specialized business units, each covering a distinct part of our circle of knowledge development, application, and innovation.

Driven to make an impact, each has a clear purpose and defined role. Yet, they follow a common mission in their joint effort of building an improved built living environment. The Nieman Groep is the catalyst of the development cycle.

We are looking for interaction within and outside our collective, with your own colleagues, clients or the stakeholders involved. This enables everyone to contribute to our projects and the ambitions of the Nieman Groep.



With energy, passion, and an eye for each other’s vision, we work on the improvement of our environment. We work on our goals with commitment and pleasure, everyone out of their own identity.



You can only stay a pioneer in development, when you dare to embrace innovation; when you go off the beaten tracks. We actively share our knowledge in order to inspire our colleagues, clients and external partners.
