Description

On Sunday, June 3, 2018, the Volcán de Fuego, situated between the departments of Sacatepéquez, Escuintla, and Chimaltenango in Guatemala, erupted twice. This disaster resulted in numerous fatalities, thousands of evacuations, many people in shelters, hundreds of injuries, and nearly two million individuals affected. Plan B Guatemala was established in response to the catastrophic eruption of Volcán de Fuego. The ASIAPRODE Association initiated this project to construct 26 homes to meet the needs of the affected communities. In an open competition, DEOC Arquitectos presented a proposal that adhered to the established requirements, the user profile, and the natural context.

The project features a permanent housing model for displaced families: an 86m² house on a plot measuring 8m by 19m. The construction is divided into two building blocks; the social-kitchen-bathroom zone is separated from the bedrooms by an interior courtyard. Circulation is minimized to ensure the best use of the various areas. The separation of the living sector into two modules allows the house to adapt to different area and site conditions. Additionally, the design permits vertical expansion above the bedroom block or horizontal growth by adding another bedroom module if a larger plot is available.

The house promotes a rural lifestyle, in touch with the outdoors, enabling families to share spaces with the community, extended family, and domestic animals. This design choice led to an open facade aesthetic, providing versatile space usage. It also supports the continuation of local lifestyles and customs, allowing them to be passed down to future generations.

The construction utilizes durable building materials that are easy to source and work with, such as concrete blocks, bamboo, and steel plate roofing. Concrete blocks were specifically used in various arrangements to create a permeable lattice that protects the inner areas while allowing natural ventilation throughout the spaces. Despite being a replicable housing model, the addition of color inside the concrete block holes offers a subtle yet strong statement, enabling families to express their personalities and fostering a stronger sense of community belonging.

This house has been designed as a self-built home, with the construction process controlled by the family or community that will reside there. It employs a traditional masonry construction method, allowing users to adjust the dimensions of different areas to the building materials, minimizing waste and reducing the construction schedule.

Main objectives of the project

On an unprecedented scale in the social rental sector, 400 future residents were involved in the design process from the very beginning. The development comprises a cluster of seven buildings, with publicly accessible communal outdoor spaces interspersed between them. The project features a diverse mix of housing types: apartments, lofts, student housing, and homes with additional space for hobbies or work. Additionally, "protected living studios" were developed and rented out in collaboration with social organizations.

Description

Housing association Woonbedrijf acquired land in a prime location in Eindhoven: Strijp-S, a former industrial area of the internationally renowned company Philips. This area was being transformed into a vibrant, trendy city district where culture, work, design, and living intersect. Initially, Woonbedrijf was uncertain about what to do with the vacant land, especially during the economic crisis when construction was at a standstill. People were more concerned with basic survival and job security than investing in new buildings.

Initially considering the creation of office spaces, Woonbedrijf soon realized that there were already enough vacant office spaces. Instead, they decided to finance a project focused on social housing. Woonbedrijf is dedicated to building, managing, and renting high-quality living spaces at affordable rents for people with low incomes. The rental income from these homes often does not cover the foundation costs, so housing associations in the Netherlands receive state aid due to their services being of general economic interest. Woonbedrijf decided to take a customer-driven approach: rather than building homes first, then finding tenants, and subsequently creating a community, they reversed the process. They planned to develop homes in collaboration with future residents, making them co-creators in the process.

Woonbedrijf, along with its student branch Vestide, reached out to potential tenants to ask what they wanted to create at Strijp-S. They recruited tenants via Facebook with the slogan, "How do you want to live on Strijp-S? Think along, from scratch!" Hundreds of responses were received, and these individuals were invited to help formulate the DNA of the future SPACE-S.

Woonbedrijf selected Inbo to design the project with the future residents, valuing Inbo's recognition of the added value of co-creation. Inbo's ability to collaborate and design with future tenants had been proven in previous assignments.

After the Facebook call, respondents were invited to share their housing wishes and participate in creating the SPACE-S DNA. Woonbedrijf and Inbo used a communication model that included online platforms (website and Facebook) and offline channels (meetings, workshops) known as “LABS.”

The design process involved rounds where Inbo addressed specific topics raised by future residents, such as floor plans and the architecture's atmosphere and appearance. They actively engaged with residents to translate their specific needs into actionable insights for the architects. Other methods included allowing residents to design their own apartments with Styrofoam blocks and using virtual reality in Inbo's VR Lab to bring preliminary designs to life.

At the end of each round, which could last up to three months, Inbo compiled all input into “COLLECTEDS.” These conclusions formed the DNA of SPACE-S and were pivotal for the architectural design.

In the SPACE-S project, home allocation was not based on registration time but on the level of involvement. The more actively participants engaged in the project, the higher their chances of securing a home. They could earn “Matspunten” (advantage points) by attending meetings and engaging online, which increased their priority in choosing a home. This system gave tenants not only a say in the design of their future homes but also a better chance of obtaining their preferred home.

This project is unparalleled in the Netherlands in its scale (402 apartments) and in prioritizing future residents' wishes in social housing. The needs expressed by future tenants led to a neighborhood where living, working, relaxing, socializing, and pursuing hobbies were seamlessly integrated. The result was seven interconnected buildings, including a 54-meter-high residential tower, offering a mix of apartments, lofts, student residences, and homes with additional space for hobbies or work. Plu-S, an organization for protected living for young people with autism, developed and rented out various studios. The design also ensured a distribution of different housing types across the buildings, fostering a diverse community where families, students, artists, and entrepreneurs live side by side.

The construction process was straightforward, except that some apartments were left unfinished for residents to customize. Lofts were double-height, allowing residents to decide whether to add an extra floor. This approach resulted in diverse interiors that met the varied needs of residents. Communal spaces were also left unfinished, as many residents were eager to personalize these areas. A notable feature of the construction was preserving an age-old plane tree on the site, with SPACE-S built around it.

SPACE-S developed a neighborhood of 402 homes on a 30,000 m² site, catering to a close-knit community within budget constraints. Most rental prices at SPACE-S are below the rent allowance limit. On almost every floor, different housing types are mixed, including:

- 151 apartments ranging from small to large, priced from 470 to 640 euros per month (excluding 59 euros service costs);
- 61 lofts, starting at 540 euros per month (excluding 59 euros service costs);
- 44 assisted living studios with three common areas (10 for Plu-S and 34 for Futuris);
- 143 student residences, including group residences from 172 to 225 euros per month and independent units from 372 to 382 euros per month (excluding 69 euros service costs).

Main objectives of the project

In the 1970s, residents of Milton-Parc rallied against the proposed demolition of their neighborhood, ultimately transforming it into the most extensive cooperative housing endeavor in North America. Presently, the Communauté Milton-Parc / Milton Parc Community (CMP) accommodates over 1500 individuals, structured into a federation comprising 15 housing cooperatives, 6 nonprofit housing initiatives, and a community-operated entity overseeing commercial properties. Notably, the project adopts a distinctive legal framework akin to a community land trust, safeguarding six downtown Montréal blocks from potential speculation and gentrification. Rigorous standards for resident selection prioritize households with limited incomes. Serving as a significant model for communal land ownership, Milton Parc has inspired similar radical housing initiatives worldwide, including the establishment of the Champlain Housing Trust in Vermont, now recognized as the largest community land trust in the United States.

Description

The genesis of the Milton Parc project traces back to a tumultuous period in 1968 within a predominantly working-class and immigrant-inhabited district of Montréal. At that time, a real estate developer, now known as Concordia Estates Ltd., embarked on acquiring the majority of the neighborhood with plans to replace its 19th-century greystone Victorian buildings with a sprawling complex encompassing shopping centers and office towers.

Over the span of 1968 to 1979, a coalition of Milton Parc residents orchestrated a series of mobilizations, comprising protests, marches to City Hall, and the establishment of essential community services like health clinics, daycares, and food-buying cooperatives. The commencement of Phase I of the developer's project in 1972 saw some residents forcibly evicted from their dwellings, leading to various forms of resistance, including the occupation of vacant houses and a sit-in at the Concordia offices, which culminated in the arrest of 56 peaceful demonstrators.

Subsequent years witnessed sustained protests that garnered attention from the developer's financial backers, prompting some to withdraw their support. Concurrently, external factors such as the 1972 international oil crisis and preparations for the 1976 Montréal Olympics led to economic instability and inflation, diminishing the value of Concordia Estates' funding and impeding the realization of their full development plan.

In 1977, amidst a shifting political landscape with the Parti Quebecois ascending to power in Quebec's provincial government and economic turbulence prompting businesses to flee the region, Concordia Estates sought to divest the depreciating Milton Parc property. Capitalizing on their decade-long organizing experience and bolstered by political changes, Milton Parc residents rallied support from various stakeholders, including a local heritage conservation nonprofit and a newly established Technical Resource Group comprising financial consultants, lawyers, and architects.

The pivotal moment arrived in 1980 when the Canada Mortgage and Housing Corporation (CMHC) officially endorsed the residents' Action Plan, paving the way for neighborhood renovations from 1980 to 1987. The financing model hinged on CMHC's purchase of the entire Milton Parc property in 1979 for USD $4.8 million, supplemented by over USD $5 million in subsidies from the CMHC, the Quebec Government, and the City of Montréal. The remaining expenses were covered through mortgage loans, with the CMHC ensuring favorable interest rates over a 35-year period to maintain rent affordability based on original rates, inclusive of minor increases to cover expenses.

Legally, the establishment of the Communauté Milton-Parc (CMP) in 1987 introduced a novel legal framework, delineating it as a "condominium for social purposes." Under this structure, housing cooperatives and nonprofits collectively own the properties, while sharing responsibilities for maintenance and services. The CMP oversees neighborhood transformation through a community-run nonprofit, resembling a community land trust model but with collective ownership of public spaces and individual ownership of buildings by cooperatives. Strict regulations outlined in the CMP's Declaration of Co-ownership safeguard against unauthorized transactions, ensuring adherence to democratic principles and self-management within the cooperatives. This intricate legal and financial arrangement underscores the residents' commitment to preserving affordable housing and fostering community-driven development.

The CMP shares similarities with a community land trust (CLT), but there are distinct differences in ownership structures. Typically, in a CLT model, the land is solely owned by the trust. However, in Milton Parc, the CMP collectively owns the land surrounding each building, including streets and public spaces, while the cooperatives own both their buildings and the land directly underneath. Similar to a land trust, any property transaction within the CMP must adhere to strict regulations outlined in the CMP’s 'Declaration of Co-ownership,' signed by all co-ops and nonprofits in 1987. Democratic self-management is central to the cooperatives' operations, with activities required to align with the principles outlined in the CMP’s Declaration of Co-ownership.

The case of Milton Parc underscores the significance of grassroots activism in securing affordable housing. Through organized resistance and community mobilization, residents were able to challenge powerful real estate interests and shape the development trajectory of their neighborhood. By leveraging political shifts and external economic factors, they successfully negotiated for governmental support and financial assistance, ultimately establishing a sustainable model of cooperative housing. This example highlights how democratic participation and collective action can effectively address housing inequalities and empower marginalized communities to shape their living environments.

Description

When planning the "new town of Chorweiler," which began construction in 1957 and stands as one of the largest satellite towns in the Federal Republic, the construction tasks were distributed among various architectural firms to achieve a diverse range of building styles. Among these, one residential complex, designed by Gottfried Böhm, stands out due to its wealth of shapes and colors, as well as its unique architectural language. This brutalist social housing complex features an innovative and bold design.

At the center of the residential complex on Ripphahnsche Strasse is a square shaped like a quarter circle. On the west side, this square is bordered by a 9-storey apartment building that follows the curve of the square. The building features a colonnade spanning the first two floors, with supports that define the structure of the façade. The dense arrangement of balconies and their vertical connections create a lively façade structure. The ground floor houses shops and a restaurant.

Opposite the 9-storey building, a house with a pergola and an L-shaped floor plan encloses the square. To the north, the square connects to a pedestrian alley. This alley is bordered on one side by residential wings, which step down in height from 9 to 7 storeys, and on the other side by two-storey apartments for the elderly.

All buildings in the residential complex are concrete structures with exposed concrete facades. Beneath the alley is a garage floor, accessible by stairs with large, green intermediate landings that also provide natural lighting for the garage.

The apartments are largely designed to be open to two opposing directions, allowing residents to experience the daily rhythm of light within their homes. The kitchens are designed as glazed rooms located in the center of the apartments. In contrast to other parts of the Chorweiler housing estate, Gottfried Böhm's ensemble is characterized by its orientation towards human scale.

Gottfried Böhm's residential complex in Chorweiler is a testament to the Brutalist tradition, showcasing bold and innovative design through its wealth of shapes, colors, and architectural language. The use of exposed concrete facades and distinctive structural elements like the colonnade and densely arranged balconies exemplifies the Brutalist aesthetic. This complex not only contributes to the architectural diversity of Chorweiler but also underscores the importance of social housing. Böhm's design emphasizes human scale and livability, with features like dual-directional openness in the apartments and naturally lit garages, enhancing the quality of life for residents. The thoughtful integration of shops, restaurants, and accessible pedestrian pathways further supports a vibrant community, illustrating how architectural excellence can serve social purposes effectively.

Main objectives of the project

Peris+Toral Arquitectes won the competition to design a building for 85 social housing units in Cornellà de Llobregat, Barcelona. The project focuses on two main axes: the design of a matrix of spaces that eliminates corridors and maximises the use of floor space through communicating rooms, and the use of wood as the main material, which allows the industrialisation of the structure, improves the quality of the construction and reduces both execution times and CO2 emissions. In addition, the building is organised around a central courtyard that acts as a communal square, promoting interaction between neighbours and guaranteeing cross ventilation and double orientation in all the dwellings.

Description

In 2017, the Barcelona office Peris+Toral Arquitectes won the ideas competition organised by AMB (the metropolitan government of Barcelona) and promoted by the public entity IMPSOL to design a project for 85 social housing units on the site formerly occupied by the emblematic Pisa cinema in the municipality of Cornellà de Llobregat, Barcelona. This project consists of a five-storey detached residential building with a wooden structure resting on a reinforced concrete ground floor for commercial and public facilities uses.

In tackling this new multi-family construction, Peris+Toral Arquitectes has highlighted two strong points in its strategy: on one hand, the design of a matrix of spaces that eliminates corridors, both private and communal, proposing communicating rooms to maximise the use of floor space; on the other, the use of wood as the principal material, which permits industrialising the structure of the building, improving the quality of the construction and reducing both execution times and emissions thanks to a totally sustainable material.

For the 10,000 m² of floor space of the new building in Cornellà de Llobregat, which houses 85 social housing units distributed over five floors, 8,300 m² of km0 wood from the forests of the Basque Country have been used. The design with communicating rooms eliminates corridors to ensure maximum use of floor space, and the use of wood favours the industrialisation of the building, improves the quality of construction and significantly reduces construction times and CO2 emissions.

The building is organised around a courtyard that articulates a sequence of intermediate spaces. On the ground floor, a portico open to the city anticipates the entrance of the building and filters the relationship between the public space and the communal courtyard, which acts as a small square for the community. Instead of having direct and independent entrances from the exterior façade to each lobby, the four vertical communication cores are located at the four corners of the courtyard, so that all the neighbours meet and converge in the courtyard-plaza. On the standard floors, the dwellings are accessed through the private terraces that make up the crown of outdoor spaces overlooking the courtyard. The general floor plan of the building is organised in a matrix of communicating rooms, with 114 spaces per floor and 543 in total, of similar dimensions, eliminating private and communal corridors to make the most of the floor plan. The server spaces are located in the central ring, while the rest of the rooms of undifferentiated use and size, of approximately 13 m², are arranged on the façade, offering different ways of living.

Another terrace in the outer crown completes the spatial sequence, connecting the spaces by means of large openings permeable to air, view and passage. The 85 dwellings are distributed in four groupings with a total of 18 dwellings per floor. Four or five dwellings are arranged around the core, so that all the typologies have cross ventilation and double orientation. The dwellings consist of five or six modules, depending on whether they have two or three bedrooms. The open and inclusive kitchen is located in the central room, acting as a distributor that replaces corridors, makes domestic work visible and avoids gender roles.

The size of the rooms offers flexibility based on ambiguity of use and functional indeterminacy, and allows for an optimal structural bay for the timber structure. In order to achieve economic viability, the volume of timber required per m² of construction has been optimised to 0.24 m³ per m² of floor area in order to achieve social housing.

Main objectives of the project

The NOU LLOC Foundation's project in Barcelona's Ensanche, located in the 22@ district, faces the challenge of providing social housing in an area marked by gentrification and rising property prices. This building of 53 small social housing units (55 m² on average) is located on a chamfered plot and stands out for its innovative design that maximises space by eliminating corridors and creating a large communal courtyard. The 22@ district, known for its transformation from a former industrial zone to a modern technological hub, has made access to housing difficult due to growing demand and high costs. This social housing project not only addresses the urgent need for affordable housing in Barcelona, but also seeks to integrate the community into a dynamic and constantly evolving urban environment, thus addressing the challenges of gentrification and social exclusion.

Description

In Barcelona, at the beginning of the 20th century, the 22@ district was born. 22@ is an ambitious urban planning project in Barcelona that seeks to transform a former industrial area into a modern district of new technologies and knowledge. This renewal plan has boosted the creation of innovative and sustainable spaces, attracting technology companies, start-ups and research centres. However, this transformation has also generated a gentrification effect, driving up housing prices and displacing original residents. Access to housing in 22@ and Barcelona in general has become increasingly difficult, exacerbating the city's housing crisis and posing significant challenges for those seeking to reside in this booming area.

It is to address these challenges that the Serra-Vives-Cartagena building was born. The project, promoted by the social housing-oriented NOU LLOC Foundation, faces an atypical programme for a chamfered plot in the Eixample district of Barcelona: 53 small dwellings (55 m² on average) and the relevant commercial premises on the ground floor.

The plot has the particularity of having a party wall open to a newly created public space. This results in a pentagon with four open facades and a party wall. The chamfer faces north and the new façade opens to the south-east. The adjacent building forms part of a consolidated complex 28 metres deep with a façade of remarkable values.

The distribution scheme that resolves the bulk of the residential programme is summarised in two bands of different depths and opposite orientations, separated by a central courtyard and articulated by the block of vertical accesses located in the pre-existing party wall.

The greatest complexity of the project arises from the strip facing the Tánger-Ávila streets, which must respect the alignment of the chamfer, so characteristic of Barcelona's Ensanche, and maintain the precise urban continuity of 19th-century Barcelona.

Both strips are aligned with the façade and the pre-existing backdrop. Access to the different dwellings is via interior walkways that converge in the only vertical access block that benefits from the courtyards of the neighbouring building. This composition creates a large courtyard on the ground floor that opens onto calle Ávila, with the vocation of an interior communal square. The most characteristic element of the building's image is to be found in the vertical cut of the chamfer, which reflects the dialogue between the two bands and opens up the inner courtyard to the light from the north.

Description

The project is located in the ‘Pere Garau’ neighbourhood of Palma (Mallorca). The area used to be characterised by blocks of single-family dwellings with interior courtyards following a typical grid plan. Once the district became a central area of the city, modifications in urban planning significantly increased building volumes and changed the typology to collective housing. The project is part of this transformation by redefining a corner plot, resulting from the union of two old houses, into a new public housing building. Moreover, it does so in a context of change in the neighbourhood. Pere Garau used to be one of the most vulnerable neighbourhoods in the city of Palma. Now it is undergoing a clear process of gentrification, the result of which could lead to the expulsion of residents. The commitment to social housing can prevent this.

The building is conceived respecting the volumetry prescribed by the regulations and taking advantage of the established rules: a buildable depth and the possibility of overhangs towards the street, half of which can be occupied with closed surface. The proposal takes advantage of this situation to create mechanisms that relate the dwelling to its immediate surroundings through openings in the volume.

The result is a perforated solid where the realities of each of the inhabitants resemble scenarios stacked one on top of the other. It is a universe of small stories organised according to a non-apparent order, whose layout arises from the relationship that the building establishes with the adjoining buildings, seeking in this dialogue to be sensitive to their scales, heights and morphology.

The different rooms of the dwelling will be organised around fixed bands that house the server packages. The excavated terraces will link interior and exterior, allowing the direct radiation of the sun and the light that penetrates to be controlled, as well as offering a landscape of its own, incorporated in the foreground of each dwelling. The rest of the openings will be protected with shutters facing the façade.

The building won the public competition to build with IBAVI, the public promoter in Mallorca. It offers 18 housing units for families. Moreover, it has won the “Ciutat de Palma 'Guillem Sagrera' de Arquitectura” 2013 award and ended up finalist in the 5th Architecture Award of Mallorca.

Description

Located in the close suburbs of Paris, the Ivry-complex, built from 1969 to 1975 as part of the "Opération Jeanne-Hachette," challenges conventional urban design with its alternative approach. Comprising eight buildings, the complex, known as "Les Etoiles," was conceived by Gailhoutet and Renaudie. It encompasses 40 social dwellings, offices, and stores, arranged in a pyramid-like structure, integrating different levels.

Among the eight buildings, three stand out: Danielle Casanova, Jeanne Hachette, and Jean-Baptiste Clément, named after notable figures. Renaudie and Gailhoutet's collaboration is evident in these structures, characterized by sharp angles, exposed concrete, and a mix of public and private spaces, showcasing Renaudie's vision of unique urban spaces.

While termed "brutalist," the Ivry-complex defies such categorization, maintaining its freshness even after nearly four decades. Its innovative design incorporates mixed public and private spaces, utilizing the third dimension with elevated walkways and greenery-covered platforms. This approach, utilizing triangles and green elements, aims to blend nature with architecture, creating a labyrinthine yet inviting environment.

Integral to the complex is its ground design, blending continuity with discontinuity. Streets permeate the buildings via interior or exterior pathways, while terraces and rooftops feature cultivable earth, hosting vegetation. This departure from the podium model, prevalent at the time, sets the Ivry-complex apart, offering autonomy to each ground fragment and varying heights.

The Place Voltaire, an octagonal square formed by Renaudie's buildings and a library honoring Antonin Artaud, serves as a vibrant public space. It caters to both residents and visitors, hosting gatherings and providing access to the subway station.

Beyond its immediate surroundings, the Ivry-complex has influenced urban development. Gailhoutet and Renaudie's methods have been replicated in subsequent projects, such as those in Saint Denis, Givors, and Saint-Martin-d’Hères, showcasing the uniqueness of each space while challenging conventional urban norms. This emphasis on creativity in suburban areas contrasts with the rigid urban schemes of central Paris, highlighting the potential of the banlieues as centers of innovation and design.

Description

The public works project, led by IBAVI, the public social housing agency in Mallorca, is located in a strategic point in Palma. Located next to the motorway belt that surrounds the city, this construction stands out as one of the last in the urban outline. In an area where low-rise single-family homes predominate, this project stands out for its boldness both in the number of housing units and in the quality of both construction and design.

The building is divided into two volumes, forming an L-shaped layout, one facing east-west and the other north-south. The two- and three-bedroom units are designed with dual orientation and employ a 20 cm thick “marés” stone (or sandstone, it is a type of stone formed by marine sand that was compressed during the Quaternary, typical of Mallorca’s buildings) period load-bearing wall structure. These walls provide thermal inertia for passive cooling, taking advantage of the cross ventilation of the sea breezes, known as the Embat de Mallorca. Unlike other public developments, such as the building in phase 1 at Salvador Espriu 18, a few blocks further down, where the buildable depth is 8 m and is resolved with stone vaults supported on the façade, in phase 2, with a buildable depth of 13.5 m, the façade is freed from its structural function to maximise the entry of natural light into the dwellings.

The timber floor slabs are supported on the party walls built with 20x20x80 cm sandstone blocks. To comply with the regulations on the maximum weight that can be handled by the operators, the marés pieces are cut in half. The structural solution is based on the Menorcan system, which has its roots in the Catalan system imported in the 13th century, while the Mallorcan system, derived from the Roman house, loads the floor slabs on the façade walls. The windows facing the public road are protected by a colonnade formed by 40x40 cm stone pillars, creating a loggia which houses roller shutters, grilles and planters with vines to provide shade and privacy for the porches and terraces.

The joint design of the buildings and public space aims to encourage residents to come out and enjoy the fresh air on summer evenings, reviving the Mallorcan tradition of sharing in the street as a communal space in hot weather. From the use of materials to the social intentionality behind the design, this project exemplifies the recovery of the Mediterranean city model, dense, compact and with public spaces that mitigate the ‘heat island’ effect. Recognised with the ‘Ciutat de Palma Guillem Sagrera’ prize for Architecture in 2022, this project illustrates how the efforts of the public administration can result in large housing developments that respect the traditions and building materials typical of the area.

Main objectives of the project

The Bon Pastor social housing project seeks to rehouse the former inhabitants of the ‘cheap houses’, the 1929 development of public housing. The project stands out for its careful integration with the existing urban fabric and its connection with the community. By preserving key elements of community life, such as shared courtyards and terraces facing the Besòs River, the design seeks to preserve the atmosphere of a village within the city. In addition, by incorporating intermediate spaces between public and private, social interaction is encouraged and the residents' sense of belonging to the neighbourhood is strengthened. This strategy not only modernises the infrastructure, but also revitalises Bon Pastor's identity as a place where the community thrives and is enriched.

Description

The Bon Pastor neighbourhood, one of the first social housing areas in Barcelona in the 20th century, was built next to the river Besós in the eastern part of the city. Initially made up of what were known as ‘cheap houses’, small, low-rise single-family buildings, it lacked facilities and public transport. However, the insistence of the residents was fundamental in transforming it into a connected and dignified neighbourhood. The Bon Pastor Remodelling Plan envisages the demolition of the 784 Casas Baratas built in 1929, to be replaced by isolated blocks for the re-housing of the inhabitants. Despite this, the aim was to preserve the community life that characterised the neighbourhood, and this is where Peris Torral's project came into play.

The new building design, agreed with the residents, has advantages in terms of high-rise housing, offering panoramic views of the Besòs river, although sacrificing part of the community life at street level. To preserve this aspect, intermediate spaces are incorporated between the public space and the dwellings. For example, communal courtyards are introduced on the ground floor, before the entrance halls, in order to maintain the community spirit. In addition, generous terraces are included on the upper floors, facing the new riverside park. The single-storey car park was designed with natural ventilation and lighting, and is adaptable over time for other uses.

The block is composed of five aggregation units, four of which house two dwellings per landing, while the fifth unit, at the front, consists of three dwellings per floor in order to orientate the rooms towards the south and create a façade instead of a simple front wall. The arrangement of the bathroom core in the centre of the floor plan allows for articulated circulations around it, providing alternative paths and a sense of spaciousness. The use of exposed brickwork as a materiality determined by the planning is used to introduce lattices that texturise the plinth of the building and provide natural ventilation to the car park and stairwells. The metal balconies incorporate a structure that allows vegetation to grow, acting as a solar filter and supporting elements such as clotheslines and textiles.

The Bon Pastor remodelling project not only seeks to modernise its infrastructure, but also to preserve its essence and connection with its surroundings. By merging the typology of high-rise housing with communal spaces on the ground floor and terraces facing the Besòs River, a harmonious integration with the surrounding urban and natural landscape is achieved. This approach gives the neighbourhood a new category, transforming it into a contemporary urban enclave that preserves its character as a village within the city. By rescuing community life and promoting social interaction through its median spaces and public areas, the project embodies the spirit of Bon Pastor as a place where community flourishes and local identity is strengthened. Ultimately, this initiative not only modernises the neighbourhood's infrastructure, but also revitalises its soul, creating a space that celebrates its heritage while looking to the future.
