All places change over time; however, the extent and availability of alternatives are essential. Friedrichshain is an example of a neighbourhood where the transition to a high-income society can have significant consequences for low-income and elderly, who have fewer choices and fewer opportunities to travel for recreation and socialising.

The design of a public condenser in Friedrichshain will form a new heart between the existing and upcoming neighbourhood and their society. The public condenser will blur the division between neighbourhoods and enhance inclusivity and diversity.

A public function that facilitates different generations' recreational and intellectual needs is a library. Today's libraries already have a social function in addition to the intellectual purpose. Adding social functions to current services ensures that the existing and new cultures and societies reinforce each other. Moreover, bringing different socioeconomic groups together reduces conflicts and disorder and enhances collective security.

This design expands the standard library with other media forms to anticipate the future. So there are printed books in the building and devices on which users can read digital books, listen to audiobooks and communicate via multimedia. In addition, the media library will contain extra functions that activate the brain's left (intellectual) and right (creative) hemispheres.

The different media types connect the thinking and doing activities in the building through a guiding routing. The guiding routing serves as an extension of the public street and is designed for stocking books and other media types, the media library.

Finally, there will also be space for leisure and gathering in addition to activities for thinking and doing. Traditional formal functions associated with a library are transformed into more informal spaces with room for the individual and the collective.
