2. Fast urban growth is the general character of developing
countries
The urban growths are resulted from the natural growth of
urban population and largely the influx from rural areas
The fast growth mainly manifests itself in many
dimensions, among them:
Housing shortage and substandard development
Dilapidations of urban centers
Lack of basic services and infrastructure
Unemployment
Unsafe urban environment
3. Addis Ababa, as one of the fast growing cities in sub-
Saharan Africa, has a critical housing problems which in
turn is reflected in:
Backlog of the housing stock
Dilapidations
Lack of basic services
Shortage of infrastructure
As part of the nation wide housing development
endeavor to solve these urban problems, Condominium
Housing was introduced to Addis Ababa .
4. Maximizing the number of housing stock through the
provisions of housing units.
Introducing coast efficient development of
condominium housing
Improving the city in terms of urban quality and
density.
Increasing job opportunities and construction skills
5. In the year 2000 has planned to execute the
planning and design of two sites in the Western and
Eastern parts of the city namely:
Jemo-II (west) with the total area of 97 hec.
Summit (east) with the total area of 251 hec.
As part of this scheme the project office invited qualified
consultants and selected two consulting firms (one for
each site) based on their technical and financial
proposals.
Our office, Consulting Architects and Engineers,
has been working on Jemo-II site closely with AAHDP
Office through multiple presentations and discussions
since the commencement of this project.
