Motivation for joining the Group
For us as a company, it was important to have strong partners at our side in a very dynamic market environment. This way, we can work with the other companies to implement complex projects and supplement our respective service portfolios with additional trades. This further differentiates us from our competitors in the project business and enables us to offer our customers an even more comprehensive renovation concept from a single source.

The professional and personal exchange among like-minded entrepreneurs is incredibly helpful for everyday challenges in operational business. Strategically, central tasks can be efficiently bundled at the group level in order to jointly shape a long-term future perspective.
