As a general planner, we combine innovative planning technologies such as BIM with sustainable design. Our portfolio ranges from interior design to comprehensive project implementation, especially for public contracts. We design projects such as kindergartens and natural swimming pools according to ecological principles and in a way that conserves resources as much as possible. BIM optimizes construction processes and reduces resource consumption to create buildings that are future-proof and sustainable.

Building in the existing stock


With a deep understanding of traditional building methods and modern techniques, we are committed to preserving the cultural heritage and at the same time creating new possibilities for use. In doing so, we place particular emphasis on fine-tuning the balance between the historic building stock and modern requirements - as well as with the relevant authorities.

Diversity

In 2024, we worked with the company Same but Different to shed light on diversity in our team. How do our employees feel represented? Do we deal sufficiently with discrimination in our day-to-day work? We first asked these questions in a survey and then evaluated them in a workshop.
