28357 Bremen-Hollerland: 200 units (not realised); model photos, well-analysed study on the failure of the project. The most important reasons: "too sterile architecture; too expensive although low-cost construction was promised; too far outside the city; the fact that the city railway was not routed to the new district after all; generally poor construction activity; major employer in Bremen went bankrupt." However, the Hollerland project caused a lot of media hype and is regarded as a model for many other projects that have since been realised, such as "Bremen-Grünenstrasse", although not on the outskirts of the city but in the city centre.

With currently 150 residents (approx. 60 units), a new self-sufficient village has been built since 1997, which enables people to live a sustainable lifestyle. There are 8 residential buildings plus the Regiohaus/Seminarzentrum, built in low-energy to passive house standards, in Sieben Linden (as of 10/2016). A straw-built guest house with 15 guest rooms is to be built in 2017/18.
44649 Herne: This is not a housing estate, but the concept could equally be applied to housing. The Naturhuset apartment house by Bengt Warne in Stockholm was one of the first pioneering buildings to implement the house-in-house principle with a shell of glass. Also the Student dormitory ESA in Kaiserslautern is built like this. The project in Herne, however, is the most spectacular of its kind in this form.
Planned in partnership by the German architectural firm HHS Planer & Architekten AG and the French architectural firm Jourda & Perraudin (Francoise Helene Jourda and Gilles Perraudin), the building is enclosed in a glass climate shell that creates a Mediterranean climate similar to that in Nice. This is on average 5 °C warmer than the outside temperature. Water features, earth channels and large gates prevent overheating in summer. The solar system in the roof, was the largest building-integrated system of its kind at the time. The supports inside are made of 56 spruce trunks. Completion: 1999
