Taking responsibility is in our DNA.
Our vision is to take genuine responsibility for our clients’ projects. However, the fragmentation of expertise and the work structures that result from it are an obstacle to this vision. This is why we have set ourselves the task of changing the market from the ground up.

We seek to take genuine responsibility based on our entrepreneurial convictions.
For the success of our clients’ projects in existing buildings and structures. For tailor-made transformation. For planning certainty and sustainability from the outset.
This attitude reflects our DNA.

We firmly believe that you can only take genuine responsibility when you offer planning and execution under one roof. That is why we seek to be the expertise leader for design&build projects in existing structures.
Our goal is to change the market for increased cooperation and more direct collaboration.

Our attitude, our community, the values we practise and our striving to achieve success for our clients’ projects.
We rely on expertise, technology and methodology to achieve this goal. We believe that nobody will be able to respond to the future’s challenges working by themselves. What is crucial is to identify and combine the right competencies for these demands. It is a matter of understanding clients and their expectations and forming individual project teams.
‘Building teams’ is the key to our success.
We are entrepreneurial in nature and enjoy our work, with all the freedoms and responsibilities that come with it. We are happy to share them with our staff. Learn more on our careers page or apply for a position with us.
