What is our point ? We already know how to produce coverage = Quantity of units. Can we, without reducing quantity, have quality as well ? Yes. Re-define quality: A house is not a car; it should be able to increase it’s value over time. Social Housing should be seen as an investment, not as a social expense. In ELEMENTAL we have identified a set of design conditions that if followed, improve the chances of a property to gain value over time, a of a family to abandon poverty. 2 million people livng in precarious conditions (15 % of the population) chile U$ 10 billion of Government Investment in the next 20 years. latinoamerica 200 milion people livng in precaroius conditions. Caracas 40% , Mexico City 60% U$ ? Billion of investment.

FRAMEWORK: Housing Policy 100.000 vouchers s x year,US$ 500 millon budget US$ 7,500 ( to pay x site, infrastructure and architecture) Income ( US$ ) US $ 5000 “Private Scheme” Gov Subsidy + Family Savings + PRIVATE BANK LOAN Used Units Mobility / Rehabilitation “Competitive Fund” Application by groups with a specific project/site Lot Subdivision / Gov Subsidy + Family Savings + SELF CONSTRUCTION Densification U$7.500 US$300 No Debt $0 New Developments


Despite very bad living conditions, families had a survival network in the city around them, consisting of jobs, education, health facilities and transportation. It was highly desireable to maintain that network and radicate the families where they were. But the problem was that the cost of the site, was 3 times more than what social housing is normally able to afford.

Which are those conditions that can increase the value? EQUATION + good location in the city Dense enough to pay for expensive well located sites (close to the opportunity network) + introduction of the collective space 20 to 30 families ( extensive family as an economical and social unit) + able to develop harmonically over time Conquer the corner of the lot / ( avoid the impoversihment of the neighborehood and of the alternate voids for expansions house typical of progressive building) 72 m2 /4 bedrooms of 3x3, living + middle class DNA of 3x6, bathroom far from entrance, (instead of small house give half of a good house) with tub not shower, parking + maximum flexibility / minimum technology 3 m. (voids big enough for decent rooms but small ehpugh to facilitate low tech expansions) + structural design for final scenario Partition walls for the final house. = all x US$ 7500 x family.(site, services and architecture included) To do what a family, individually, will never do.

If to try resolve the equation we use 1 house = 1 family = 1 lot… We fit just 32 units This type is very inefficient in landuse, so the market tries to make land cost as close to zero as possible. Those pieces of land are far away, in the periphery of cities; in this case in a stigmatized town outside Iquique. But even if we had enough money to 32 units pay for this site, this isolated type is unable to take some responsibility on selfconstruction (50% of the final built environment at least). The given units are normally swallowed by expansions producing a very bad urban environment, once again.

If we use a more dense type Lot width = House width = Room width… We fit 60 families. We do better, eventhough still not enough. The problem with this Row House type, is that whenever families expand, they block previous rooms’ access to ventilation and light, and compromise privacy. What we get then, instead of efficiency in landuse, is overcrowding. 60 units

If we build in height… We fit all the 100 families But ( besides the fact that families threatened us with a hunger strike, if we even consider giving these blocks as a solution), building in height 100 units blocks expansions.

So, instead of doing the best possible $7.500 dollar unit and repeating it a 100 times, we went for best possible $750.000 dollar building which could host a 100 families and their growth in time. But we knew, buildings block expansions… That’s true except in the first and last floor; So, what we did was a $750.000 dollar building that had just the first and last floor. With 2 properties one on top of the other, we doubled the efficiency of landuse, before even ging into the design.

1. Dry automatic unarticulated Boxes and Forms to counterbalance selfconstruction 2. Alternate voids avoid overdose of uncertain 3. Loos/Tzara windows to achieve scale 4.

The First-and-Last-Floor-Building, wrapped around to form 4 collective courtyards of 20 families each Square 9 x 9 m lots for the house, allow to fit better the irregular shape of the site. Form matters.

Meanwhile, families began to be prepared for the new life they were about to begin. They had to begin to think about the new houses, so they were asked to draw and write about…

Expected expansion The Growth

This is what you normally get while building for $7.500, 45 minutes away from the city, in a stigmatized periphery

For the same money we did this, in the same place where they have lived for the last 30 years, paying 3 times more than what social housing has ever paid for the land.

Second 50% = US$ 750 First 50% = US$ 7,500 US$ 7,500 + US$ 750 = US$ 20,000
