Prins Group, the greenhouse constructor with over 80 years'​ experience, develops your complete project from the greenhouse to all the related systems. With engineering and production managed in-house we are able to respond quickly and efficiently to different situations and developments. The projects can be executed by our own assembly teams equipped with a modern machine fleet. It is also possible for us to train local assembly teams led by our experienced supervisors.
