When Auctioning 272 Vacant Properties from Itaipu, Housing Project Uses Technology That Builds Affordable Housing in One Day to Relocate Families from Stilt Houses in Foz do Iguaçu, Build 160 Houses in Castro, and Test a Sustainable Model of Social Housing That Can Be Replicated in Different Regions Throughout the Country in the Coming Years.
With a housing deficit approaching 10 thousand affordable homes, Foz do Iguaçu has seen the birth of an unusual solution: Itaipu Binacional decided to turn empty houses into a resource to fund a program that builds affordable housing in one day, relocates families living in stilt houses, and restores preservation areas to the environment.
By auctioning 272 vacant properties from Vila A, the company directs the raised funds to the Housing Project, which combines rapid construction technology, social focus, and sustainability. The goal is to move families from risky areas, reduce the housing deficit, and create a model that can be replicated by public authorities in other Brazilian cities, while maintaining the same logic of repurposing idle assets in favor of those who need it most.
Housing Deficit, Stilt Houses, and Vacant Homes in the Triple Frontier
Before the Housing Project, Foz do Iguaçu lived with a paradoxical scenario. On one side, there were shacks in technical areas, green spaces, and riverbanks, irregular occupations with almost no adequate sanitary conditions.

Brazilian city gains industrial hub for 85 companies that is equivalent to 55 football fields.

Peugeot and Citroën factory in Argentina cuts production by half and opens a layoff program for more than 2,000 employees after Brazil drastically reduced purchases of Argentine vehicles.

A Brazilian city gains a factory worth R$ 300 million with the capacity to process 200 thousand tons of wheat per year, a mill of 660 tons/day, silos for 42 thousand tons, and an industrial area of 276 thousand m².

Havan will leave the shopping mall in Blumenau to inaugurate something that the chain has never done before: a megastore in half-timbered style in the Historic Center of the city, which is expected to be completed in May and change the landscape of local retail.
On the other side, Itaipu Binacional accumulated vacant houses that required ongoing management, something far from the central mission of the plant.
When the hydroelectric plant was built in the 1970s, the company brought thousands of workers in different roles to the triple frontier. To house this workforce, it erected three housing complexes: Vila A, Vila B, and Vila C, each with a specific profile.
Vila A housed technical and administrative staff, in American-style houses, many of which were wooden. Vila B was designated for upper management, with high-standard residences. Vila C was created as temporary accommodation for the construction sector, featuring shared housing in simple barracks and more rudimentary infrastructure.
With the end of the construction work and a significant reduction in personnel, the houses in Vila B were sold, Vila C was transferred to private individuals, and Vila A was left with more than 900 properties, hundreds of them empty. Itaipu found itself with an asset that no longer served its core activity and generated only maintenance costs.
How the Housing Project Was Born in Foz do Iguaçu
Faced with this situation, the binational’s board chose to auction off 272 vacant properties and invest the proceeds in affordable housing for the vulnerable population.
From this decision, the Housing Project emerged, a joint initiative of Itaipu Binacional, Itaipu Parquetec, the city hall of Foz do Iguaçu, and the Municipal Housing Institute (FozHabita).
In the first phase, the program will benefit 254 families in social vulnerability, with houses of 50 square meters built in an area in the Três Bandeiras neighborhood.
Last Tuesday, Itaipu delivered the first 52 houses, intended for families who lived in stilt houses in a Permanent Preservation Area, degraded and subject to flooding.
These families leave wooden structures on flooded areas to occupy brick houses, with basic infrastructure and formal addresses.
The leap in dignity is immediate: the constant risk of flooding is replaced with the concrete possibility of planning for the future outside the stilt houses. At the same time, the relocation paves the way to recover the degraded APP.
By using the auction proceeds and a technology that builds affordable housing in one day, the project connects housing solutions, environmental recovery, and efficient public asset management, creating a practical case of social policy financed by the reorganization of the company’s own assets.
Technology That Builds Affordable Housing in One Day and Reduces Waste
The technical differential of the Housing Project lies in the construction system chosen. The program uses a sustainable method capable of building each house in just one day, with pre-planned pieces and components, which allows accelerating the schedule and limiting the impact of the construction site.
In practice, this means that the same financial base from the auctions can generate more units in less time, with less material waste.
Less rubble, less construction time, and more cost predictability form the central equation of the model. Instead of months of traditional construction, the schedule is compressed, allowing for reaching more families in short timeframes.
This same logic is directly connected to the guiding principle that directs the project: a technology that builds affordable housing in one day, focused on those living in risky areas.
The goal is not only to quickly erect walls but to deliver sustainable housing, with structural and environmental quality, reducing waste generation and excessive resource use.
Agility also helps provide quicker responses to social emergency situations. Families that previously depended on years of waiting in housing programs can now access a home within a timeframe that matches the urgency of their reality.
Castro Will Be the Next Laboratory for the Sustainable Model
The experience in Foz do Iguaçu will not be isolated. The second phase of the Housing Project will be implemented in Castro, Paraná, where R$ 30 million will be invested in the construction of 160 affordable houses, expected to begin early next year.
Just like in Foz, the proposal is to use the same concept: auctions and resources linked to Itaipu, partnerships with the municipal government, and the technology that builds affordable housing in one day to serve low-income families.
The focus is to create a comparison base between different cities, measuring social, environmental, and financial results.
If the performance in Castro confirms the speed and efficiency gain observed in Foz do Iguaçu, the Housing Project can establish itself as a reference for housing programs in other states.
The idea is to show that it is possible to combine constructive innovation, social focus, and sustainability without sacrificing cost control.
At the same time, the case of Castro will help define how far the model can be replicated in municipalities with different urban realities, varied infrastructure, and diverse levels of housing deficit. This understanding will be crucial for any national expansion.
A Possible Path for Public Housing Policies
More than a localized project, Itaipu’s experience points to a format of action that can inspire new public policies.
Transforming idle properties into a source of financing for social housing, using technology that builds affordable housing in one day and articulating partnerships with city halls and housing institutes are pieces of the same innovative policy design.
This design shows a state capable of reorganizing its assets, tackling concrete housing deficits, and restoring degraded environmental areas, instead of merely bearing the bureaucratic burden of vacant properties. The logic is simple: where there was maintenance cost, there is now a measurable and objective social investment.
In the end, the project leaves an essential question for public debate: is it worth more to maintain immobilized and underutilized assets or to convert them into real homes, with addresses and infrastructure, for families who today live in stilt houses and risky areas?
If the technology that builds affordable housing in one day proves to be consistent and scalable, it could become an important part of the repertoire of housing solutions in Brazil.
In your opinion, should the government expand this model of quick and sustainable affordable housing to other cities in the country?
