1st PRIZE Alumed-Strong Contest 2017


1st Prize to SSS in the contest of ideas called by ALUMED-STRONG for design of SOCIAL HOUSING in an area of TROPICAL AFRICA.

The jury unanimously decided to highlight the proposal presented by SSS “for the response it brings to an urban reality of large African cities. It proposes a very simple typology, by the configuration in parallel bands that brings, through the galleries, a wide spatial, functional and climatic wealth. In turn, it allows versatility through the variation of the building type”.

The Republic of Ghana is one of the most prosperous and stable countries in West Africa. In 2011 it was the country that grew the most in the world after Qatar. This year, its economy grows to 6% and forecasts for 2018 are 6.2% according to the IMF. In the last five years, the country’s population has grown by 2.6 million people, and will continue to grow at a dizzying rate of 3%, the same growth rate as its urban population, which is 50% of the total. For these reasons we look at Ghana, a country where freedom, progress and democracy are breathed, and there is oil. BUT ALSO BECAUSE THERE ARE 2 MILLION INFRASTRUCTURES OR 30% OF THEIR POPULATION LIVES UNDER THE THRESHOLD OF POVERTY, among others.
Migration from the countryside to the city in the Accra Region (The Greater Accra), has been and is being massive. Soon, this mega city will contain 20% of the country’s population: 4 million people. And the destination of the migrated are the extensive settlements of the periphery or informal coastal neighborhoods like James Town or compact neighborhoods in the center of the city like Nima. The Greater Accra is a model of a young African megalopolis that needs new approaches to urban densification and new large-scale social housing policies. This is why we are in the city of Accra.
Nima Neighborhood
One of the most populous neighborhoods in Accra is Nima. It is a place of inhabitants migrated from the countryside, of high density, high-density, very low and very compact, where about 30,000 people live in just 1 km2. It is a very vital but poor place and affected by chronic urban degradation. The urban regeneration of this area is our starting point and the ultimate goal of our proposal in this contest.

HA777Urban regeneration
The urban project we propose requires public investment and private initiative, something similar to the phenomenon of “gentrification” in Anglo-Saxon countries, or the “machizukuri” planning figure in the Far East countries, or “urban acupuncture” in Latin America. All of them are strategies of urban regeneration of consolidated and deteriorated neighborhoods in the big cities, rich and poor, on the one hand based on creating new public spaces to oxygenate and decongest the urban fabric, and on the other, increase the density of buildings in certain well connected areas.
The urban regeneration in the Nima neighborhood consist of two large operations: opening small public spaces connected to one another by expropriating certain areas of the fabric and densifying the edges of the main artery of the neighborhood (Nima Road) providing a large percentage of the land to social housing or rehousing, which is fundamentally the subject of this contest.
Architectural strategy
The densification at the edges of the commercial corridor Nima Road will build a more urban and profitable city. It is about taking advantage of the natural vitality of this artery that crosses the neighborhood from end to end and multiply its intensity, and in this way create more space and better connected inside the African city.
The architecture of social housing must be modular and flexible. If it is, it will accommodate the masses and build a spatial identity of its own over time. For this we propose a modular skeleton (Stands) based on walls and concrete slabs assembled with aluminum formwork of the STRONG FORM AND / OR ALUMED system, and a set of adaptable light elements (Skins) that will condition the modular space depending on the Orientation of the building, its urban position and the needs of the real estate market. Modular supports and flexible skins are the two elements that build our project.
The tropical climate forces the air currents to cross the spaces to increase the thermal comfort. High temperatures and relative humidity are combated with shaded spaces, lattices and solar protections and cross ventilation. The dwelling in the tropics should be a space between the exterior and the interior, a space in shaded and airy where to spend the torrid and endless tropical summers and covered with the rainfall of the monsoon.

Horizontal Landscape

The landscape where we will build the school is a horizontal landscape of the savannah. There are no tall treetops or large geographic features. The territory is horizontal. And the architecture of the new school also it is. They are buildings glued to the ground, which extend horizontally, hidden in the low savannah thicket. Thus, the new construction  and the landscape will melt into one. Mimesis with the environment is one of the important skills when you come to a place. Our school will be a group of buildings that will touch the ground, of low height, and will extend by the savannah camouflaged with its ocher color.

sss_04_2016_secondary_school_tabora_tanzania_04Itaga mission is 12 kilometres north of Tabora town, in Tanzania. The mission serves 32 villages. The population of the area is 20,000. The main economic activity of the people in this area is small scale farming and animal keeping. In every village we serve there is at least a primary school. Most of the inhabitants of this area engage in small scale farming. The area also has Public Secondary Schools. Most of them are day based schools; that is students stay at their homes and go to school at daily routine. This makes them have poor performance in academics. Due to this and other reasons stated in number three, the Archdiocese of Tabora came up with an idea of founding a boarding school.The school will be located in Makenenya estate in Itaga village.

The school will be a boarding school which at the beginning is expected to accommodate 100 students. The school is expected to serve 60 villages from Itaga Parish and Kashishi quasi Parish. Yet, this does not rule out the possibility of getting some students from other nearby areas. As stated above at the beginning the school will have 100 students after four years it is expected to have 400 students.

Plan of uses.


The buildings are organized as a fan, following the sun’s course from sunrise to sunset, like a bird that opens its wings to take advantage of the force of the wind. The fan shape takes advantage of the forces of nature and adapts itself to the slight orography of the savanna landscape.


If the buildings flow towards the landscape in all directions towards the west, in the opposite direction they are directed toward a single point to the east. The Agora. The agora will be the heart of the school, center of culture and social life, for everything flows into the agora as a river directs its course towards the ocean.

The buildings are a large shade that will protect from the strong radiation of the savannah. A horizontal and wide shadow, like African acacias. In this shadow lie the rooms, the classrooms, the dining room, the offices and the auditorium.

Two spaces

The rooms have a double space. A night space and a day space. The night space is in contact with the ground, sheltered and quiet. The day space is in contact with the horizon.

More information about the Master Plan for the Asunción Bay :

Affordable housing in a developing country should be simple. It must have the essential constructive elements of the place where it is constructed. In a subtropical country with long, hot, humid summers, the patio appears as an element more than adequate to relieve the suffocating heat. In that courtyard, a typical Lapacho tree of Paraguay appears, full of beautiful pink flowers.

And outside, the street where the Paraguayans trade and live the long days. The houses are grouped generating an irregular urban space, with shadows and lights and taking advantage of the predominant currents of air that refresh the patio dwelling.

SSS_04_2010_urban_waterfron_Asuncion_Paraguay_01Under the almost hypnotic influence of the Paraguay river, the road superstructure mimics the flow of the water and distributed trafficking parallel to the water surface.




Four streets begin at Bicentennial Park and temporarily end up in General Santos Avenue, the last of the big toes that structure the Great Asuncion.



This structure of wide streets continue along the coast of Asuncion, accompanying the construction of the Costanera Avenue, bordering the Pytá lagoon, crossing the creek Mburicao to the Botanical Garden to connect with the Transchaco route; thus completing a coastal tour of 8700 meters.
