Introduction
3. Citizens making City – The Tübingen Model
What is a “Baugemeinschaft“ or “Baugruppe“?
Baugemeinschaft Baugruppe ?
(In English: “Private Building Cooperation” or “Joint Building
Venture”)
A “Private Building Cooperation” is a kind of joint venture
between several private households who plan and build
their own house together. Usually they are supported by an
architect. Often „Private Building Cooperations“ are able
to realize high-quality living space at prices that are well
below going market rates.

When the house is finished, normally it will be divided into
individually owned properties.

Where does it come from?
The principle “Private Building Cooperation” is not new.
In Germany it became popular in the 1990th in South

- during the conversion of former French barracks into new
housing areas…
Introduction
6. Citizens making City – The Tübingen Model
Where does it come from?

In Tübingen the city council promoted “Private Building
Cooperations” to realize the mixed used city structures in
the “Südstadt”.
Meanwhile the “Private Building Cooperation”- movement
spilled over to many other German towns: Berlin,
Hamburg, Leipzig, Munich, Stuttgart and many others…
