Aachen urgently needs more affordable housing. To create this and make it available in the long term, land must be acquired and developed o na non-profit basis. The available land is scarce. Therefore, concrete solutions must be designed now. These homes must be able to accommodate a variety of people and lifestyles. This work negotiates between guidelines & needs & between doors & walls. The result is a porous spatial structure, a house with many rooms of the same size waiting to be inhabited. The project aims to find answers to many questions, including:

How can we use the last vacant lots of our cities to create socially appropriate housing?
Which principles should socially appropriate housing follow?
Are the current laws & regulations on social housing reasonable or do they inhibit the design of good living spaces?
Which changes should be made to these regulations that might aid in the creation of more good housing for the many?

The answers are given through the design, set on a vacant lot on a busy commuter-street, and a booklet of theses on how to built & preserve socially just housing. The floorpan consists of many rooms of almost equal size. Each flat has a base-set of rooms an entrance & kitchen, a central communal room & a bathroom. Depending on how many people inhabit the flat, the equivalent number of rooms are added, while always remaining in the given spatial limitations of the regional guidelines.
These rooms are not given a specific function but can rather be inhabited as needed, encouraging different ways of living together. Every wall has an opening so that the entire floor could be connected. This porous structure is filled with either doors or panels - connecting or closing off rooms. According to changing family structures throughout the inhabitants ́ lifetimes their flat can grow and shrink with them, given that their neighbors change as well. Otherwise, the homogeneous structure encourages swapping flats, too.
