59yard, while with a second movement it creates an abrupt reduction of the space, re-
sulting in a narrowing that coincides with the junction of all the residential streets
with the Stresemannallee (the former Wilhelmstrasse) that constitutes the eastern
boundary of the housing complex. Alongside the Stresemannallee, the final wings of
the hooks form a long, high, unbroken, and straight urban elevation that gives access
at regular intervals to the residential streets.
On the west side each of the residential streets leads to the Heimatring (fig-
ure 29). These junctions also are given an architectural accent—every row is pro-
longed over the Heimatring and ends with a wing at right angles to the residential
street, forming the urban elevation of the Heimatring. These striking ends mean that
a clearly defined boundary is set up in this Siedlungbetween what is “inside” the
Siedlungand what is “outside.” In the Siedlungitself, however, there is no hierarchy,
and, unlike Römerstadt, it has no definite center. This is partly due to the nonhierar-
chical character of the Zeilenbauprinciple and partly to the lack of community facili-
ties such as those that contribute to the centralizing character of the Hadrianstrasse
in Römerstadt (shops, catering facilities, and the school).
The Zeilenbauprinciple was modified not only by these very definite bound-
aries but also by the subtle way that every street is given its own character. It is true58
