Description

The team published the story of this collaborative process as a comic (“Commons”), from the winning project of the Europan 10 competition in Vienna and its later development with a multidisciplinary team until its definitive passing by the Vienna City Council. “Commons” obtained recognition as an example of innovative, sustainable and democratic urbanism.

One of the most challenging issues of today is the question whether housing in itself, as a programme, has the power to generate an urban neighbouthood. “Garden>Courtyard” plays the ball straight back to the municipality, developers and users, suggesting an extrapolated concept of mixing with just a single programme-housing: housing with diverse models of living, diverse models of sharing, diverse models of developing, diverse models of financing, diverse models of landscaping, diverse models of maintaining.

Once the masterplan approved, the landowner (ARE, Austrian Real State) commissioned multiple architecture teams as well as different sporsors to develop an edification design. In the partnership with the Viennese enterprise for social housing and different cooperatives, a collaborative democratic and plural urbanism process was created.
Arenas Basabe Palacios was commissioned with the design and execution of 11 housing blocks in different scales, including 82 housing units with a total of 9500 m2 constructed surface containing community spaces, shared parking facilities for bicycles and commercial spaces in the ground floor for zone.

The design respects the original urban idea and furthermore creates new potential based on the garden-matrix, which is structuring the new district. Each block is constructed around its garden while edification varies in height, bay and edification type: constructions of small scale (size S) contain single-family housing and duplex; Medium-scaled buildings (size M) as their taller complements (size L) serve as collective housing blocks and develop a diverse and porous urban process.

The materiality of the buildings accentuates this idea: Ceramic colour facades are facing the sun, while all living spaces are south-orientated and opened towards the garden. The more intimate bedrooms can be accessed through privacy filters in form of halls which contain service rooms installations and space for storage.

The dwelling´s interiors reflect the characteristic construction system: together with white carpentry, visible vertically perforated bricks (“Hochlochziegel”) are creating a sequence of neutral, flexible and reconfigurable spaces.

Main objectives of the project

The project comprises 105 senior citizens' housing units and features a double-height plinth with a Health Centre and Senior Community Centre. The design fosters a dynamic community and preserves the existing social network of the neighborhood. Located near Glories' square, the project integrates with the urban fabric of Eixample and responds to Diagonal Street. Three housing volumes on top of the plinth accommodate the program. Each building has seven or eight dwellings per floor, connected by a central corridor. Communal spaces include a rooftop terrace, laundry, porch, and patio-solarium. The layout promotes a sense of limitless interconnectedness, with movable walls and open spaces. The construction system incorporates thermal insulation and a district heating system, resulting in high energy efficiency.

Description

The project organises 105 senior citizens housing into three volumes spread out, on top of a double-height plinth containing a Health Centre and a Senior Community Centre. The building’s common spaces help to create a dynamic community. The mixed-use of the program enable to preserve the existing social network of the neighbourhood. The project is located near Glories’ square. This plot is within the Eixample’s urban fabric. At the same time, is part of a city block trimmed by Diagonal’s Street trace.

One of the main challenges the project had to face was the mixed-use program with different real estate developments: 105 housing for Barcelona’s council, a Health Centre for regional government, a Senior Community Centre for the district and a vehicle impoundment parking for BSM. We opted for a unitary building in order to organise and to encourage different uses but also to accommodate the whole program: a group of three volumes of housing on top of one double-height plinth containing the facilities.

By overlapping two different urban strategies, the project is capable of giving response to the surroundings’ complexity. On one hand, the continuous base of the building recognises the grid of the Eixample, by leaning on its alignments. On the other, the housing volumes give continuity to the sequence of nearby isolated blocks in respond to Diagonal Street. The void between these blocks is necessary to filter the public space through and to maintain the global unit. The result is an architectural ensemble that despite its domestic height is able to dialogue with the unique geometry of the high and sharped nearby buildings, joining into a greater scale urban piece of strong identity.

Depending on the block, each building has seven or eight dwellings by floor with a central corridor. This walkway enlarges at both ends where it receives daylight.

At the top floor of each building there are a communal laundry, a covered porch with clothes lines and a patio-solarium with foreseen urban-garden.

At the plinth’s roof level, each building has a multi-use room connected directly with the outside terrace enabling the social services managing the building to organise workshops or activities.

This communal terrace, located at the treetops’ height and endowed with benches, is opened to the surrounding views. It integrates the three blocks into a larger community of neighbours.

Considering these are dwellings for elderly, users are meant to spend long periods of time at home and at the building. Thus, communal spaces enhance and enrich the experience of living. This dwelling’s typology is organised around a central core of serving spaces, which is surrounded by the bedroom and the living room, both understood as a continuous and flexible space articulated by the terrace. This layout enables to perceive space as limitless, not enclosed but interconnected. The bathroom segregates into two pieces: a more private area and an open space.

Spaces connect or segregate through large sliding doors, like movable walls. If they are all open, space flows around the core. Depending on whether doors either open or close, space is transformed so it can be differently used.

The corner’s typology repeats the same scheme of serving spaces. The entrance threshold is enlarged to host the dinning room, linked by a window to the kitchen. The sights connect with the exterior through a large series of frames. The enfilade of doors and windows increase the porosity of space; and as a result, space seems larger than it is.

Rooms are never enclosed, they always vanish into neighbouring spaces slightly introduced for the occupant to imagine. Tangent views flow around the core, linking contiguous spaces.

The dwellings’s structure consists on perimeter walls and pillars always located on the in-between apartments walls so that a free plant is guaranteed. It is at the ground floor level and by using cross-beams where the structure turns into an orthogonal grid of pillars of 7,5×7,5m for the parking located at the lower floors.

The construction system of the housing façade is different than the one for the plinth. The one of the dwellings consists in External Thermal Insulation Composite System (ETICS) improving the thermal inertia of the building, whereas in the lower floors Glass Reinforced Concrete (GRC) is used. Both systems guarantee a thermal break, providing maximum comfort.

The building is connected to a district heating system, providing sanitary hot water and central heating. Inside the houses, we opted for a low-temperature underfloor-heating system in order to obtain greater comfort with less consumption. Due to all these resources, the building is qualified with an A for European energy labeling.

Main objectives of the project

85 social housing units in Cornellà de Llobregat (Barcelona) utilize 8,300 m2 of zero-kilometer timber from the Basque Country. The building features a courtyard that connects intermediate spaces, with a porch on the ground floor serving as an entrance and a meeting point for occupants. The floor plan maximizes space utilization by eliminating corridors, and the rooms are arranged in a matrix layout. The structure incorporates cross-laminated timber walls and laminated timber columns and beams. The façade utilizes an electro welded wire mesh construction system for sun shading and terrace handrails. The timber volume per square meter is optimized at 0.24m3/m2 for economic feasibility in social housing.

Description

85 dwellings, 543 spaces and 2172 corners For the 10,000 m2 of built surface area of the new building in Cornellà de Llobregat (Barcelona), consisting of 85 social housing units laid out on five levels, a total of 8,300 m2 of zero kilometre timber from the Basque Country has been used. The bases of this new residential building are a matrix of communicating rooms that eliminates corridors to guarantee optimum use of the floor plan and the use of timber to enable the industrialization of elements, improved quality of construction and a major reduction of deadlines and C02 emissions.

The building is organized around a courtyard that articulates a sequence of intermediate spaces. On the ground floor, a porch opens up to the city, anticipating the doorway of the building and filtering the relationship between public space and the courtyard that acts as a small plaza for the community. The four vertical communication shafts are situated at the four corners of the courtyard so that all the occupants converge and meet in the plaza, which represents a safe space from a gender perspective. On the model floor, entry to the apartments is from the communication shaft and the private terraces that make up the ring of outdoor spaces that overlook the courtyard. The building’s general floor plan is a matrix of communicating rooms. There are 114 spaces per floor, all of similar dimensions, eliminating both private and community corridors to make the maximum use of the floor space. The server spaces are laid out in the central ring, while the rest of the rooms, of undifferentiated use and size (13 m2), in the façade, accommodate different forms of occupation. The surface area and proportion allow generous corners as a support that facilitates the appropriation of space. The structure is mainly determined by setting 3,60m short spans, matching the matrix of rooms. Therefore, multiple supports uphold CLT slabs: cross-laminated timber bearing walls in the façade and a system of laminated timber columns and beams in the centred bays. The structure is optimised by compensating momentums with multiple supports and cantilevers at all ends.

In order to achieve economic feasibility in social housing, timber volume needed by built squared metre is been optimised down to 0,24m3/m2

The façade’s construction system and the structure joints are both solved by mechanical bonds, avoiding the use of scaffolds. The exterior building skin is built up with electro welded wire mesh, holding/bearing sun shading and filtering sights. By bending, this element improve steadiness and at the same time it shapes the terrace’s handrail.

Urban Design

Main objectives of the project

By revitalizing and adding floors to a 16th-century building, mia2 Architects demonstrate that responsible urban development can be aesthetically, socially, and economically successful. They removed the pitched roof of the artisan's house, replacing it with a new structure that respects the city's cultural memory. This courageous step of continuing the building, rather than demolishing it, improves its functionality and comfort while preserving its historical significance. The design incorporates a green space and a front element with balconies, creating a welcoming atmosphere and rejecting the anonymity of the city. Construction elements like exposed timber beams, concrete beams, and historical rubble walls add unique character to each space. The facade of Lederergasse, after thorough cleaning, reveals its solid structure, while the timber building on top showcases a rhythmic and reflective design.

Description

In revitalising and adding further floors to the sixteen century building we wanted to show that continuing building in the city is a responsible way can be successful not just in aesthetic terms but also socially and economically. For us, this project is a passion, experiment and space for life. mia2 removed the pitched roof of the originally three storey artisan´s house, replacing it with a new building. This new structure takes up the eaves height of the adjoining 19th century corner house and is inscribed precisely within the maximum contours for the roof space permitted by the building authorities. Upon taking a closer look what could, conceivably, sound like yet another repetition of an all-too familiar procedure, i. e. “investor maximises usable floor area“ turns out to be a courageous step and one that is far too seldom taken – given the desolate state and the oppressively low ceiling heights of the existing building, few clients wouldn`t have thought twice about demolition in order to build the maximum permitted volume.

A city is, not least of all, a memory in built form. mia2 show respect for the everyday culture of the past. With this revitalisation they prove that it is possible to raise a building´s cultural level while also improving its functionality and level of comfort.

By continuing this building, they demonstrate belief in the future of the city as a form of settlement that, in order to remain successful, has always had to combine flexibility with meeting the most elemental human needs. While this green space is not that large and it plays a significant role in the concept. A front element with balconies extends along the entire south front of the building. Next to the lift shaft a new spiral stairs as a continuation of the historic central corridor winds upwards, enriching the courtyard with an element of movement. It is like a greeting, a wave, also to the residents of the surrounding buildings: the often-invoked anonymity of the city is not cultivated here.

Construction elements such as the timber beams of the existing building that were stripped from hideous layer, or the concrete beams above the wide window openings in the new building are exposed. Historical rubble walls, clay obtained during the ground floor excavation work and used to make a rammed earth wall, the specially developed precast concrete elements for the new staircase or the green polycarbonate grilles of the balcony slabs make each space something special. In comparison the front of Lederergasse appears severe. After a thorough cleaning of its facade the old building now shows again what it is: a solidly built structure with a rendered, hole-in-the wall facade. In the timber building on top of it mia2 Architektur developed this motif further: from a vertically articulated front with openings to a rhythmically structured envelope, which, through the gently reflective volumes of the two dormers, seems to dissolve in the light of the sky.

Main objectives of the project

The Illa de la Llum project is located at the intersection of Avinguda Garcia Faria and Selva de Mar, forming part of the Diagonal Mar operation. The site has limited space and follows a rigid urban plan. The towers maximize the available area, allowing for varied dimensions and layouts. The towers incorporate deliberate excavations and recesses to reduce excess height and create connections between neighboring towers. Inside the towers, strips define the corridors, utility spaces, and dwellings, offering flexibility in layout. Continuous terraces project outward from the habitable strip.

Description

The project consists of a set of dwellings standing on the intersection between Avinguda Garcia Faria and Selva de Mar, known as the Illa de la Llum (Island of Light), and forms part of the Diagonal Mar operation. The urban plan clearly defines a 32,940 m2 site available for construction to be shared among three buildings. Everything is very precise, with little leeway for manoeuvre, and responds to a highly debatable model that disregards links between facades and the street.

This project clearly rejects the compositional obsession with slenderness, as if it were an unquestionable compositional value. Indeed, the towers take maximum advantage of available ground area, thereby making it possible to build dwellings of different dimensions and distributions. They reach the compulsory height and the excess buildability that would result from all floors being identical is reduced and adjusted by means of deliberate excavations , recesses that increase as height is gained and which are conducted in areas that look northwards, zones without sea views or else at the points of greatest proximity between the towers.

In the towers and around each nucleus of stairs and lifts a series of strips have been defined that totally encompass the nucleus in the big tower and only three of its sides in the smaller one. The nearest is the access corridor to the dwellings. The next one, 50 cm wide, accommodates pillars and utilities. The broadest strip, 8 m wide, houses the dwellings, in which the total absence of fixed vertical elements makes a great variety of distributions possible. Another 50-cm strip once again accommodates utilities, structure and the walls that separate the habitable strip from the continuous terraces that project 3 m outwards.

Description

The transformation project of the warehouse building of the old industrial complex of Fabra & Coats in Barcelona is included in the process of reconversion of this textile complex of the XIX and XX centuries to incorporate it to the "BCN creation factories" network.
The intervention in the building activates all the elements of the original building creating the new program, and reuses its physical, spatial and historical qualities to make the new construction more efficient and to reinforce the character of the original building.

The original building is 100m long, where the first decision was to bring the value of its maximum dimension, which is the length. We access through the center creating an interior square where the promenade of the interior stairs begins in diagonal double ascending. The original building is communicated physically and visually from the ground level until the roof structure. This vestibule also connects the building to Parellada Street and the Fabra & Coats complex square. This new communal space is the new structural contribution to the original building.

The new construction is by assemblage, it is a dry construction with just few materials, as in the original industrial building. Wood is used in all its forms: solid, agglomerated, cross laminated… Materials are joined as if it was a textile. To sew and un-sew, the new construction by its character and assemblage, can be assembled and disassembled, so it is “reversible”. The building, in the future, as a heritage element, can return to its original form of 1905, and the material used in its construction can be recycled.

Structural reuse of the two inner floors of the building, using them without any reinforcement (load capacity of 1,100kg/m2) to support on both floors the two new levels of housing. We convert two floors into four, to reach this we use a wooden structure, because it is 5 times lighter than a steel structure. The wooden frame structure is a translation of the old steel structures used as shelves for the storage of the threads.

Façade and roof of the building as a thermic buffer for the housing units. The new housing units are placed separated from the façade and the original roof of the building, with a new wooden façade.

The in-between space is created to circulate the air; therefore, the housing units do not require the air conditioning the most part of the year. The 45cm brick wall and the ceramic tile roof of the original building provide its thermal and shading properties to the new interior building, while maintaining its presence as an interior façade of the communal spaces. In this in-between space are the inner streets to access to the houses, identifying the old path of the thread packages through the crane bridge and the conveyor belts. The former textile complex of Fabra & Coats in Barcelona, built between the 19th and 20th centuries, is being gradually recovered to incorporate it into the “BCN creation factories” network. More than 28,000m2 in public buildings and social housing will be added to the Sant Andreu neighborhood.

One side of the building, the result of an extension on 1950, has been destined for the headquarters of the “Colla Castellera Jove” in Barcelona. The adjacent building, 100 m long, has been transformed into a complex of 46 social housing units.

To configure the main space, the training room for human towers (10x10x10 m), is based on the analysis of human towers: pyramidal structures that work, ideally, with pure compression. Due to their operation, they fill the space, creating an empty space around them.

The new structure is conceived in a complementary way to a human tower: it works like a shell, creating an empty space inside. The upper floor under roof is a three-dimensional suspended structure that does not make its operation evident.

The project combines for the first time the rehabilitation of industrial heritage, the creation of social housing and wood construction. The elastic joints of the new elements resolve the compatibility between the two constructions and achieve acoustic comfort in homes that is higher than the standard.
