Welcome to our office!

We’re passionate about the Ruhr metropolitan area – we have been here since 1959 and are in our second generation of ownership. But the collected experience of our 70-strong team extends far beyond the local region: from Essen to China, Dubai, England, Georgia, Ireland and Russia. Our principles are the same there as they are here: a customer and solution-oriented approach and absolute dependability when it comes to quality, meeting deadlines and budget, combined with the utmost creativity and total dedication.

We love buildings down to the smallest of detail

We share our passion for building with our 70-strong team – be it for residential and administration buildings or educational, commercial and logistics establishments. We’re both generalists and specialists for our clients, providing support with architectural questions, construction management tasks and consulting services. Our approach is characterised by flat hierarchical structures, open communication and goal-oriented decision-making processes.
