Who we are

Healthy, sustainable space. For everyone.
Our mission

“The solutions for sustainability in the construction and property industry are available. The task now is to close the numerous implementation gaps.”
Dr. Birgit Memminger-Rieve
Our values

We scrutinise our impact on our environment and shape it as positively as possible. We always pursue the goal of going beyond our customers’ requirements and jointly pushing the boundaries of what is possible.

We are curious, we ask questions differently, and we think outside the box – and thus bring the familiar into new, relevant contexts. This also applies to topics that go beyond the property industry. In this way, we constantly broaden our horizons and are open to discovering new things.

To initiate change, we go far beyond the industry standard. With accountability and curiosity, complemented by our tenacity and passion for developing outstanding solutions for a circular construction and property industry, we are turning our vision into reality step by step.
Our team
Only different perspectives and experiences reveal the big picture.
