RIO DE JANEIRO
• Total population 2010: 18,171,711• Rio de Janeiro: 6,323,037• Metro area: 11,848,674
• Density: 4,781 km2• 2nd largest contributor to GDP• 22% of the total population lives in favelas. • 1,071 Favelas according to the 2010
census• Affordable Housing Crisis
FAVELAS IN RIO DE JANEIRO
SUMMARY
Favelas and High Rise Housing in Rio de Janeiro
FAVELA CHARACTERISTICS
• Neighborhoods that emerge from a need for housing• Established and developed without external or government
regulation• Their original blueprint established and developed organically and
by residents themselves• Continuously evolving based on culture, access to resources and
jobs• Run by Residents Associations• No legal protection to the ‘property owners’/no access to secure
land tenure • Limited upward mobility in the formal sector • Health/Safety/Welfare – no enforcement of building codes, drugs/
gangs/violence is a continuing issue, and militias have a strong-hold on the residents’ welfare
• Gentrification leads to rising rents and displacement; UPPs have increased safety in many favelas, further amplifying price increases
FAVELAS TODAY
Rio das Pedras 2014
FAVELAS IN BRAZIL
• 1937: Federal District Building Code: favelas are declared illegal and announced demolition
• 1950s-80s: State and Church sponsor favelas improvements• 1982-1990:
• Brizola Administration several infrastructure upgrades are undertaken (water & sewage hookups, trash collection, public lighting)
• Cada Familia, Um Lote: land regularization-14,000 lots• Mid 90s: IDB creates urban upgrade program “Favela Barrio.”
Infrastructure investments worth US 600mn• Programa Morar Legal: regularization of 24,000 households
• Today: 3rd phase of IBD’s program “Morar Carioc”, which aims to upgrade all favelas in Rio by 2020
• Initial round only covers 30 favelas in Rio and 6 irregular settlements through a 150 million loan

MINHA CASA MINHA VIDA: PLANNED FOR AMBEV SITE
• Primary affordable housing program at a federal level.• Government has promised to deliver millions of units within the
current presidency.• Residents given voucher to purchase housing.• Shortcomings:
• Mono-Use Residential• Low Density Housing • Restrictive in design • Public gathering spaces are poorly designed, if not lacking
completely. • Developments are often located far from sources of
employment • Lack adequate public transport access • Quality vs. Quantity - Government less concerned with
construction quality. New developments located in virtually worthless land.
• All these factors often lead to failed developments, where new communities are afflicted by high vacancy, credit loss or crime. The Minha Casa Minha Vida Program fails to recognize and replicate the positive conditions of informal settlements, proposing overly-formalized housing communities. This model of development often leads to housing stock which depreciates, rather than appreciates over time.
MINHA CASA MINHA VIDA PROJECT
WHAT IS SITES AND SERVICES?
• Government provides and prepares land with essential infrastructure needed for habitation
• Prepared plots sold or leased to beneficiaries• Beneficiaries use their own resources to construct their homes• Basic Infrastructure - Supplied by Government
• Water Supply • Electrical Service • Sewage System• Storm Drainage • Street Lighting
• Access to infrastructure - Supplied by Government• Each plot set up to connect to water, power, sewer
• Planned Community Services & Facilities - Supplied by Government• Schools• Health Centers• Community Centers• Playgrounds/Recreation/Open Space • Security post • Bus shelters

CASE STUDY: ELEMENTAL
Limited resources for affordable housing are invested to build half of a good house, rather than a full house with poor construction. The savings in construction are reinvested towards a site which is more strategically located with a higher-land value. A better Location should permit the property to appreciate in time, rather than depreciate.
The user will respond to this ‘half-house’ by wanting to expand it over time. The design accommodates for this incremental growth with an adjacent void, mitigating the risk of structural failure and over-crowdedness.
The units are built with cheap prefabricated concrete panels and assembled on site and left virtually ‘raw’, with limited finishes. Users then self-improve their homes, selecting the tiling or exterior paint color to their liking.
