1: 1000 Site plan
10m slope gradient
Cohab’s plan is to cram as much
In between 2 two-way Roads
apartments into the site without
Top road : Rua Joãƒo Kowal
any consideration of
Bottom road: Rua Acir Perira
1. The site context
Conserved vegetation on the
2. Social conditions
East of the site
3. Future developments.
Cohab house design (Not meeting the need of users)
Loss of Eco-diversity as a result of urban sprawl
Expansion of boundaries and alteration of internal space
Insufficient housing for low income people living in slumps
Construction of wall fences
Most homes in Brazil are poorly insulated homes with zinc roofs and concrete walls
Unsightly Litter
Bad living conditions in river settlement favelas
Resident: Diverse family unit
Government: balancing between cost and quality of living space

Condensed Living
This Japanese phrase captures the essence of ‘not wasting’.
A single component that can perform many functions.

2. Lack of housing for low income communities --> de nsifying the site 3. Cheap and little materials to construct homes.

Extended family/ Standard nucleus family/ Single parent family
Efficiency 5. Communal space to promote social cohesion
3. Spacing out homes to prevent overshadowing.

Small, tall and narrower homes require less materials Energy saving --> adjacent buildings reduces heating of up to 30-40% Reduce urban sprawl Optimising space : Free plan --> utilising partitions
1. Loss of Environment --> reduce materials and architecture footprint
Dwelling 1: (more efficient space) 2 Bedroom + 1 Living bedroom + Bigger living room space Single parent Standard nucleus family Dwelling 2: (more privacy option) 2 Bedroom + 1 Living room - Smaller living room + More private spaces Single parent Standard nucleus family
