Project description by jury
The project’s objective is to provide housing for the low-income riverside population of Manaus currently living in precarious and risky conditions. The design takes inspiration from the traditional stilt and floating house typology to not only suit the local environmental conditions (including the seasonal fluctuation in water levels of the river) but also to recover and recognize the value of indigenous cultural identity. The complex is organized on three different levels: a primary floating level mainly used for fishing and resting, a second floor above the water where collective commercial and cultural spaces are located, and an upper level occupied by dwellings. The project also includes a landscape intervention that connects with public leisure areas. Particular attention is paid to the optimization of natural resources through the adoption of water reuse and solar energy systems. To strengthen the local economy, material supply consists almost exclusively of local wood, and the local labor force is involved in the construction.
The work is a compelling alternative to the prevalent social housing provisions currently offered in Brazil, which too often ignore social and cultural specificities of local communities. The Holcim Awards jury Latin America applauded the quality of the project, sensitive to the climate and coherent with the Amazonian culture. The design emphasizes the importance of rescuing the vernacular riverside architecture while offering high quality spaces. The interplay of solids and voids that characterizes the complex was acknowledged as both very functional and of aesthetically merit. The modular structure assembly system, which allows for self-construction and replication, becomes an incentive for social inclusiveness. The jury also highlighted the attention paid to water treatment, which indicates a real awareness of ways to minimize environmental issues linked to water pollution in the area. The high quality of this resilient architecture was unanimously acknowledged and considered an inspiration for similar projects elsewhere in the world.See more
Ethical standards and social inclusion: Population as a protagonist
Throughout the project execution, the local population will assume a protagonist role, starting from the supply of building materials to the engineering and use of labour force, which will strengthen the local economy. Once completed, the complex will not only offer quality housing but also a space that fosters culture and leisure activities. As a result, a sense of community is created and empowered. The access to those activities is intended for not only the residents of the complex, but also the surrounding communities. In that way, the complex generates a micro local economy and cultural center for the region. All the public spaces within the project are accessible to physically impaired people.
Contextual & aesthetic impact: Nature and architecture integrated
Amazon basin water levels vary throughout the seasons and, therefore, the building structure needs to adapt according to those changes. The design of the housing complex was inspired by the traditional Amazon architecture in such a manner that is in harmony with the people and its environment. The way this is done is by elevating the complex from the ground, as a reference to the popular stilt house. A floating floor, that varies in accordance with flood and ebb seasons, is also created, which is a common technique found in floating houses of the region, that allows for a continuous dialog with the local landscape. A requalification of the landscape is also done through the creation of a park that dialogues with the cultural and leisure spaces of the project.
Resource and environmental performance
Aiming environmental sustainability, the project makes the best of available natural resources: The rain water is harvested and utilized in toilets. Sewage water is treated so it does not further pollute rivers and can eventually be reutilized. The solar energy is an alternative renewable energy used to provide electricity to the complex. Thermal comfort is done naturally by the dissipation of heat through cross ventilation. Also, the roof protects the interior spaces from direct rays of sunlight. The main structure of the building is made of reforested wood, which, during growth, absorbs carbon dioxide and generates less residues during the construction phase. The building does not touch the ground, causing a smaller impact on the existing land and vegetation.See more
The Next Generation 1st prize for Latin America went to Buoyant Housing in Brazil – Riverside living and community complex by Danielle Gregorio, student at the University of São Paulo, Brazil.
The riverside residents of Manaus live in a flood zone. The project proposes a type of social housing adapted to the local conditions, which is inspired by traditional stilt and floating house typologies. The complex includes a community center for cultural and leisure activities that aims to build social cohesion. It consists of a floating level for fishing and leisure activities, a level for collective commercial and cultural purposes, and a level for apartments. The project relies on locally sourced materials and makes best use of natural resources. Rainwater is harvested and used. Shading and cross-ventilation enhance the indoor climate.
“The project incorporates local architecture and design features so that the building is in harmony with the people and the natural landscape,” explains prize winner Danielle Gregorio, student of architecture at the University of São Paolo. This approach is also appreciated by the jury, which praises the project for being responsive to the climate and coherent with Amazonian culture. It shows a deep awareness of how the environmental impact of interventions can be minimized. “This project found the perfect scale of intervention and the ideal mix of social and material priorities, and natural impact,” says Marilyne Andersen: “It’s feasible, respectful, and just right.”
Los residentes de la zona ribereña de Manaos viven en un área de alto riesgo de inundación. El proyecto propone un tipo de viviendas sociales que se adapta a las condiciones locales, y está inspirado en las tipologías tradicionales de casas flotantes sostenidas por pilotes. El complejo incluye unidades habitacionales de calidad y un centro comunitario para el desarrollo de actividades recreativas y culturales, con el fin de fortalecer la cohesión social. Está organizado en tres niveles: un primer nivel flotante destinado principalmente a la pesca y a actividades recreativas, un segundo nivel para fines culturales y comerciales colectivos y un tercer nivel en el que se ubican los departamentos. El proyecto incluye el aprovechamiento de materiales naturales disponibles localmente. Se propone recolectar y reutilizar el agua de lluvia y recurre al uso de la sombra y la ventilación cruzada para un mayor confort interior.
“La propuesta incorpora aspectos de diseño y arquitectura local para que la construcción esté en armonía con la gente y con el paisaje natural”, explica Danielle Gregorio, estudiante de arquitectura de la Universidad de San Pablo. Este enfoque también fue apreciado por el jurado, que destacó que el proyecto fuera sensible al clima y coherente con la cultura amazónica. Demuestra profunda conciencia acerca de cómo minimizar el impacto ambiental de las intervenciones. “Este proyecto logró la escala perfecta para la intervención y la combinación ideal entre prioridades sociales, materiales, e impacto natural”, destaca Marilyne Andersen: “Es viable, respetuoso, y adecuado.”

Our website search engine covers the web pages including project descriptions and expert profiles, PDFs, images and videos on the Holcim Foundation website. To improve your search results, here are some tips:
Our search defaults to term-pairing AND. If you search sustainable construction - then the search engine will look for any items containing sustainable AND construction
photovoltaic OR solar
Looks for either word
(clay OR mud) AND (school OR university)
Combine alternative terms for more specific searching
Excludes a term from results, automatically ANDs other terms listed
Use quotation marks to search for a specific phrase or combination
Asterisk (*) matches any word or phrase - so archit* will find architect, architecture, architectural as well as architrave
