FINAL PRESENTATION OF GMO CITY

FIRST STEP

An attractive element in a site,absorbing new incomes and attracting a new type of popula-tion.

STEP TWO

After a certain development,a community will start to form itself and old residents not corresponding to those standards will leave beause of prospections or di�erences,a new type ofpopulation having the same caracteristics will be the gentri�ers of the neighbo-rhood.

STEP THREE

When a neighborhood reaches its develop-ment peack,prospection and land value will increase and reach a point where even me-mebers of the same copmmunity will have to move,and then the process will start back.

Positive effects of Gentrification. Negative effects of Gentrification

5-EDUCATION LEVEL INCREASED

1-PRIVATE FONDSEconomic strength to renovate the district

2-DENSITY INCREASESUrban structuration and structures are more used

3-MIXITY OF DISTRICTSDevelopment is a global benefit for all classes

4-YOUNGER POPULATIONThe reuse of the district creates a vibrant life within the neighborhood;attractif for youngers.

More the population increases more edu-cation becomes an important part of the

society.

1-Eviction of low-income classes anddisparition of initial original community.

2-Increasement of Rent Prices.

RULES FOR GENTRIFICATION

- FIRST STEP: EVALUATION OF CELLS QUALITIES

ACTIVITY RULES

Gentrification as a growing process depends on the status of each zone toward its area : giving optimal opportunitiesl or not for gentrification to happend

SOUND : Silent to noisy SUN : Sunny to shaded PROXIMITY : Well served to Less served

Each "empty" cell is impacted from the cell surroundings throughout different radius according to there nature and attraction power
