The building sector is one of the largest contributors to climate-damaging emissions. According to the German Sustainable Building Council (DGNB), this sector is responsible for up to 30% of greenhouse gas emissions in Germany. Construction and demolition waste accounts for 54% of the waste generated in Germany. Sustainable planning can help conserve and reuse resources. Sustainable construction also creates a healthy indoor environment – a particularly crucial factor as people now spend 90% of their time indoors.

What we do

In close collaboration with our clients, we consider interior design holistically. Attractive design, user well-being, health and environmental aspects are all equally incorporated into our concepts. Together with the clients, we define individual sustainability goals for each project at an early stage. We then consistently consider and implement these goals from the planning stage through to completion. In this way, we contribute to a positively designed, healthy and sustainably built environment.

Phase Sustainability

Since 2020, we have been participating in the Phase Sustainability initiative, a project by the German Sustainable Building Council (DGNB) and the Federal Chamber of Architects. The goal of this initiative is to transform planning practice towards sustainability as the new norm. Through our participation, we aim to accelerate necessary changes and contribute to climate protection alongside other specialist planners. In as many projects as possible, sustainability goals will be defined and mutually agreed upon with the clients.


Carolina Hahn (Cologne branch) and Oliver Schau (Hamburg branch) are our contact persons in our offices, offering their expertise in the field of sustainability. However, all our team members are committed to this cause.

We look forward to implementing exciting and sustainable projects with you.

Internally, we also strive for sustainable practices in our office routines. We commute in an energy-conscious manner, promote season tickets and leased bicycles for our employees, and we opt for train travel whenever possible.
We practice responsible use of resources by, for example, reducing paper consumption and the amount of waste and using environmentally friendly electricity and water dispensers.
We care about the well-being of our team members, supporting sports activities, offering flexible working hours, providing nutritious snacks and ensuring ergonomic workspaces.
