Our companies

Prommenz's strength lies in its wide range of services. Since 2021, Smit Groenadvies has become part of Prommenz. In this way, we have optimized our collaboration and can better unburden the client. Since 2023, Buro Mien Ruys has also been part of Prommenz. With this collaboration, the design team is expanded while maintaining quality and expertise. SAS and Hollands Kroon Architectuur have been part of the Prommenz Group since 2025.
