About us

Already since 1948, Valstar Simonis has been an independent Dutch consultancy and engineering agency in the field of sustainability, comfort, and safety in buildings. With our enthusiastic team of consultants and engineers we provide custom-made solutions for each project from our five branches in the Netherlands. We design all building installations combining our expertise in mechanical, electrical and building control systems.

Since 1972 the name was changed into “Bureau Valstar | Simonis b.v.” consulting engineers ONRI, later abbreviated to Valstar Simonis. In 1995 a side-branch was opened in Apeldoorn in order to support our projects in the region, and in 1998 a branch was set up in Eindhoven. Since 2008 the branches in Amsterdam and Groningen have been added to that. You will want to be able to build on our expertise. And on our people. We are happy to show you how our organisation is set up and which people we employ. Valstar Simonis has around seventy permanent staff, subdivided over all disciplines. Because of this we are capable to guarantee continuity and switch quickly. All these people are qualified and very experienced. We regularly welcome young people who have an academic or higher vocational training. The average age is about forty years.
