22045 Hamburg-JenfeldHAMBURG WATER Cycle®, an urban quarter with 835 residential units, 630 of them in new buildings, and commercial space for around 2000 residents is being built on 35 ha of the former Lettow-Vorbeck barracks. Project costs: approx. 250 million euros. The most far-reaching project of a decentralised water supply and disposal system currently in Europe: vacuum toilets, biogas production and waste water separation (HAMBURG WATER Cycle®). The biogas produced will be used to generate heat and electricity for the new district in a climate-neutral manner in the district's own combined heat and power plant. The project will thus enable climate-neutral living and sustainable drainage.

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.
30539 Hanover-Kronsberg: Sub-project of the Expo 2000 new housing development. 106 apartments with large solar collectors on the roofs, as well as solar local heating with seasonal storage. It is located in the southeastern part of the district. Completion: 2000

33649 Bielefeld-Quelle: 96 units, architect: Hans-Friedrich Bültmann, special features: all buildings are equipped with composting toilets and the highest composting toilet in Europe is located on the 5th floor. Further water measures: rainwater infiltration, own drinking water source; a reed sewage treatment plant was planned but could not be realised.

Economy: Development as a large plot, low-cost construction with partly much own work. Construction time: 1997
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
