Historical background
1639-1778, - Pre urbanization period - nomadic settlement. The city location changed 28 times from the ancient capital HAR-HORUM to NIISLEL HUREE that evolved into a religious, political and international trade development center of the country.
1778 until now which the sedentary civilization period begun with, or the period of struggling for the development and national symbol.
During these periods, the city managed to maintain the current status of the socio-economic and political center.
Ulaanbaatar urban development divided two periods:
Dambadarjaa monastry 1765

Urbanization of UB city.

Urban development steps in UB city In 1960-1965, the city location and construction layouts initiated.
In 1965-1975, the city general plan formulated with economic efficiency estimations based on land maps, and comprehensive engineering and geological surveys.
In 1975-1985, the capital city urbanization works were carried out based on the national policy, methodological directions and norm-standards, well adjusted to the national territorial, natural, climatic specifics.
In 1985-1990, numerous national experts on projecting and urbanization had been trained, thus enabling the national manpower to carry out independently all projecting works well fitting to the Mongolian local conditions.
From 1990, in conjunction with the socio-political changes and transitions to the free market economy, a new radical trend emerged in the UB urbanization plan, and currently in force legal acts serving basic norms and standards.
Nomads lifestyle
Traditional Mongolian Dwelling
Ideally suited to Mongolia's nomadic way of life and harsh weather, the Ger has been the most popular dwelling for hundreds of years.
A round wooden-framed felt tent covered in durable white canvas seems to be the most simple description of this portable home. The modern shape of the Mongolian Ger has been formed as the result of the long development through huts, marquees and wheeled abodes. During ancient times, people made shelters from dry branches and animal skins. This could have been the first version of current Mongolian Ger. The history of the Ger goes back to 2500-3000 years BC. In medieval era large Gers that belong to kings and nomadic chieftains were built on special wheeled floors and were dragged by a number of oxen (22 at usual).
Interior of the Ger, and structure
The Mongolian Ger has two key component: the wooden frame work and the felt cover. The wooden wall shell is called 'khana', the upper wooden poles (measuring 1.5-3 meters) are 'uni', the central supporting two columns are known as 'bagana' and the uppermost smoke hole is 'toono'. A Ger has 4-12 khanas, depending on its size. The number of uni or upper poles ranges between 45 and 120 depending on the number of khanas. Any ger has a toono ,the smoke hole and baganas, 2 columns supporting the toono. There are several felt layers, covering the wooden framework and outer white canvas which is designed to make the Ger look prettier and protect the felt covers from rain and snow. Mongolian nomads, who move several times each year, pack their Gers onto the back of camels or camel and ox carts. The weight of a ger is approximately 250kg-s.It only takes half an hour to collapse an average ger and a bit longer to re-build it.

Research of problem finding
The comments discussed during meetings
Lack of kindergartens, schools and other social services facilities, which creates major problems for residents
- In case of construction of apartment houses, residents could give land for construction and get apartments in return
- It is needed to plan a safe road - Options on how different size of land, which
varies between 0,3-0,7 hectares, owned by various people will be reflected in the project planning
- Effectiveness of land re-planning projects
Public participation
- Whether different treatment shall be used for people who grow in their yards trees and other plants
- After planning stage, when implementation phase will start and finish
- The role and participation of the capital city municipality and the Ministry of Construction and Urban Development
- Solutions proposed for families which reside on someone else’s yard and do not own the land
- Type of apartment buildings to be built
- Parties which will participate in the implementation process.

“Neighborhood Residential Unit” Planning
This is a basic urban planning unit to plot community facilities such as kindergarten, elementary school and parks in residential area. Basically, service coverage of 1 school is a basic unit, which consists of 7,000 – 10,000 population.
