Erläuterungstext

1. City growing is organic growing
Every step in the evolutionary process of a City’s growth is based on existing circumstances and facts like history, nature, culture, current needs etc. A city is never finally built, but always changing, growing or shrinking. It is a permanent process of transformation, from rural to urban landscape, from old to
new, from small to big - and reversely. According to this principle, the new city of Gia Lam, Trau Quy town, gains its basic structure from the existing settlement and its network of paths, ditches, fields and rivers. In a simple process of transformation, a ditch becomes a canal, a path becomes a street, and a paddy field becomes a lot. This strategy creates the opportunity to the authorities to develop the city step by step, according to actual needs and potentials. The city growing remains sustainable, healthy and flexible.

2. City as a cellular organism
Like any other organism, the city is organized in a cellular structure. Some cells are specialized and high developed, others achieve basic function to keep the system alive. Apart from such technical and functional aspects, social life is organized in cells and clusters, too. One of the basic units is the family itself, which
plays in Vietnam a very important role in social life. Family members care one to each another in many ways in everyday life. The strategy considers this fact by providing diverse units in different scales. It starts with apartments, grouped to houses, houses are grouped to neighborhoods, and they are grouped to areas. Many different types of open spaces can be created and offer a wide range of opportunities for the inhabitants to communicate from door to door, from house to house or from street to street.

3. Open space structures the city
The city lives from its open spaces. Green belts of parks and landscapes connect the different
areas of Hanoi. They create a network of green areas which basically structure the urban body
and provide open space and fresh air for the inhabitants. Trau Quy town lies within a wide, open landscape
and is surrounded by large scale parks which lead to other parts of Hanoi City. It will be created as a garden city with thousands of trees, a wide range of parks and squares in different shapes and of different sizes and of large Boulevards for business, shopping and leisure.

4. The city is built on water
Water plays an important role in Vietnamese culture, history and religion. Water affects almost every part of the city’s life, in good as well as in bad sense, and demonstrates how the city learned to live with its streams, floods and dangers. As a matter of fact, water has to be considered in many ways, not only for
irrigation or drainage, but also as an important factor to create a comfortable climate in the hot season of the city. Based on the existing grid of channels and trenches, water accompanies many roads, squares and parks and is in every angle of the new town a visible and present factor.

5. An ecological city
The urban design follows ecological aspects in a wide range, touching many different aspects, e.g.:
- a careful planning and construction of buildings, with good isolation and appropriate exposition and alignment of the building due to wind and sun influence, with deeply structured facades of buildings to shade in natural ways, with natural circulation of fresh air;
- careful and respectful handling of natural resources, efficient waste-water treatment, gravity drainage, protection of the environment;
- efficient land-use and easy system of infrastructural development
- creating a comfortable atmosphere with shading trees and air cooling water surfaces of ponds, lakes and canals;
- a high quality of technical infrastructure,
- short ways for managing the workaday life and to run the daily errands without using the car,
- an accurate number of kindergardens and schools of high quality to prevent short distances to educational facilities
- location of scientific park near the city and its infrastructure to create synergies, short distances to business and capital as well as to public transport facilities like train station or bus terminal
