4 Linden is a place where art and culture, architecture and aesthetics, nature and ecology come together. You can feel this as soon as you set foot over the threshold.

This harmony between man and nature is based on 12 values that we have developed ourselves and try to put into practice every day.

You can take some of these values home with you, or benefit from our experience in your projects in Aachen, Europe or worldwide. The scale does not matter as long as we follow the values of humanity and caring for nature.

Andreas Dilthey offers his services as an architect in the fields of ecological building, project development and development aid, as well as the production of marble inlays, portraits and objects in the field of architecture.

The residents of 4 Linden can also offer their services and talents, ideally these skills will complement each other.
