This paper will try to investigate the minimum parameters that are required to create vernacular urban spaces through proposing a new strategy for the slums upgrading projects by finding the similarities between vernacular urbanism and slums. By this way we could help the governments (especially in the third world countries) to find out a way to solve their housing problems through the rapid increase in population growth, without facing the troubles of the informal areas and slums phenomena and to achieve sustainable housing development depending on the concept of “Self Built” environments.
SUSTAINABLE ARCHITECTURE
Since architecture and environment have a close relationship in terms of cause and effect, better building and a more sustainable architecture will be one of the solutions toward sustainability.
SELF-BUILT ARCHITECTURE
Vernacular approach
In vernacular architecture it is equally reasonable for people in daily connection with nature to seek its conquest through processes that smooth the rough and brighten the dull, altering the natural into artificial.

| 説明を追加 |
The change of ecology, mixing culture, technology and economic development has changed the vernacular architecture.
Problems
- The problem of the false identity of ecological systems,
- The problem of design and planning as deceit about ecological systems
- The problem of invisible ecological systems. These problems for environmental policy may be resolved in part if urban planners and policy-makers use socially recognized signs to display human intentions for ecological systems.
Informal approach-Slums:
There are a set of broad “context” local, global, market, and regulatory that constrain and inform all areas of urban design actions. Although theses contexts change over time at any particular moment they are relatively fixed and typically outside the scope of the urban design practitioner influence.
Factors affecting the urban context of self-built environments
These factors are: (Location, Topography, Climate, Land sub-division, Economical factor, Socio-cultural factor, Building materials/ methods).
Physical elements of self-built environments:
The Minimum elements which required creating vernacular urban spaces through the slums upgrading
Some main elements are taken into a study to investigate the minimum parameters that are required to create vernacular urban spaces through the slums upgrading projects by finding the similarities between vernacular urbanism and slums.
New strategy of upgrading slum areas in developing countries using vernacular trends - Three phases
FIRST PHASE- Planning Adjustment
a. Layout and building lines b. Space networks c. Town cramming and density d. Street width e. Form of urban tissue f. Road hierarchy
SECOND PHASE - Facades Adjustment; this stage will help in improving the visual image as a whole, through changing in the building`s facades.
a. Openings b. Materials and colors c. Elevation width d. Block size e. Texture
THIRD PHASE - Urban Image Adjustment; when upgrading using a successful landmark, respecting edges of the surrounding environment, and using roofs according to the activities required, there should be a unique image for each individual area.
CONCLUSIONS:
- Through this study we find that we can adapt some urban elements in the Informal environment areas to transform them into environment using Vernacular.
- By this way we could help the governments to find out a way to solve their housing problems through the rapid increase in population growth.
- Where the simple elegance of things which are designed to do their job functionally and effectively and which communicate visually.
