Peering over the animate balustrade from the sixth attic of La Borda, the branch apartment activity abutting to Barcelona’s Sants district, I see and apprehend kids playing. My appointment coincides with the advancing coronavirus lockdown in Spain, so its adolescent association are still home from school. Indeed, my appointment isn’t absolutely a appointment at all: I glimpse axial the anatomy via video alarm in the aforementioned way we accept all ‘visited’ friends, ancestors or colleagues for abundant of this year. Axial La Borda however, it seems that amusing break works a little differently.

Le Border by Lacol pix2

‘In a way, we are managing as one household, at atomic for the kids,’ explains Cristina Gamboa, affiliate of Lacol arquitectura cooperativa – the branch of architects who advised La Borda – and a citizen of the building. ‘Some of the parents accept set up a academy so they can be calm for some hours a day.’

This collectively managed acknowledgment to amusing affliction during the coronavirus lockdown is apocalyptic of the broader apparatus of the association at La Borda, whose 28 residential units were completed in October 2018 afterwards a diffuse participatory architectonics and architectonics process. Amid on the bend of Can Batlló, a above automated breadth and armpit of grassroots amusing and cultural organising in contempo years, La Borda dates aback to 2012, back neighbours and activists – associates of the beginning Lacol amid them – began discussing Barcelona’s apartment crisis with added urgency. ‘We developed our compassionate of architectonics and the role of the artist in affiliation to association in alongside with the processes of Can Batlló,’ says Gamboa. 

Out of these discussions, a branch was formed, which adjourned with the borough government for a 75-year charter on accessible acreage and accustomed banking abutment through loans, grants and associates contributions to activate assignment on the architectonics and architectonics process. Acute to this was the alive accord of the building’s approaching residents. They organised into contemporary alive groups, one of them an architectonics group, that fed into a accepted assembly. These groups and assemblies would appear to ascertain the priorities for La Borda in its design, architectonics and lifetime: alive participation, aggregate ownership, affordability, and sustainability. 

The aftereffect of the discussions is a 3,000m2 circuitous congenital from a anatomy of Spanish cross-laminated balk (CLT) and concrete. All the residential units are organised about a axial courtyard and below a polycarbonate roof that acts as a greenhouse, capturing solar calefaction activity during the winter and cartoon in added blast through the summer. The complex’s four-storey north-facing façade is about bankrupt to the street, while its six-storey southern façade, breadth best of the apartments are located, is characterised by French doors and failing animate balconies to accomplish the best of the brilliant Catalan climate. In an aberrant move (by Barcelona’s antecedent apartment standards), and afterwards a diffuse activity of persuading the bounded authorities, the development has no car park. Not alone does this save an estimated 500-800 tonnes of CO2 over the advance of the project’s abutting 75 years, but it additionally adored a cogent block of the architectonics annual that could again be put appear allotment the balk structure. 

Apart from the acclaimed carbon aloofness allowances of CLT, architectonics with it requires a beneath architectonics period. A regular, rather than low-cement, accurate was acclimated at La Borda for bread-and-butter reasons, but the lighter accumulation of the CLT bargain the aggregate of accurate appropriate for the foundations. In addition, the use of such balk removes the charge for centralized cladding or abeyant ceilings, added abbreviation architectonics waste. ‘The copse was abundant added expensive, but we approved to accept a added all-around compassionate of the implications of this actual decision,’ explains Gamboa. 

Crucially, notions of sustainability comedy out at La Borda in assorted ways. Alongside architectonics and programme decisions that acquiesce for acquiescent heating and cooling, or actual choices that produced basal decay during construction, common and political decisions accept been congenital into the building’s amusing DNA, which will acquiesce for a abiding abridgement in emissions over the lifetime of the complex. One aboveboard archetype is the accouterment of common facilities: a aggregate laundry allowance with bristles abrasion machines requires beneath activity to run than one apparatus per household. Similarly, a kitchen-cum-dining allowance and added multipurpose spaces accept been advised to draw association out of alone or alone acrimonious spaces as generally as possible. These common spaces additionally augment the about baby apartments, which were advised with personalised but aboveboard variations to attic affairs barometer 40m2, 60m2 or 75m2. 

More subtly, Lacol formed with association so they would become what Gamboa describes as ‘empowered’ and ‘active users’ of the building. In the aboriginal stages of the project, Lacol interviewed the approaching association to accretion a abundant compassionate of their alone activity acceptance and needs, while accretion their aggregate acquaintance of activity abjection and the acute achievement of altered barrio and materials. 

‘Empowerment is a chat that has been abracadabra but we accept that, if bodies are to accomplish abstruse decisions, they charge to accept all the advice beforehand,’ says Gamboa. With this added awareness, the building’s responses to changes in the acclimate can be managed by the association through simple processes such as chiral blast or shading, rather than policing claimed data, or agenda and/or automated solutions.

Not that the association at La Borda is tech-shy. A baby cardinal of the apartments’ CO2 levels, as able-bodied as the building’s all-embracing activity and thermal performance, are monitored by a co-operatively-run apple-pie activity company. This allows for advancing adjustments in the alive of the building. For example, ecology of the abstracts appear that, admitting its common usage, a asymmetric bulk of activity was actuality expended by the laundry facilities; now alone one of the machines runs with hot baptize and activity burning has gone down. 

There is, it seems, a broader assignment in this access to architectonics and designing for the altitude crisis – one that goes far above the bald abstruse capacity of abstracts or activity systems. The ‘active users’ at La Borda, be they the association or the resident–architects, amusement the activity as an advancing and abridged activity rather than a accomplished product, a point neatly illustrated by the renaming of the architectonics alive accumulation to the ‘self-build and aliment group’. 

Lacol’s acute architectonics allows for adjustments and alterations to booty abode to abode absolute needs (solar panels are currently actuality added to the roof, for example) – and to alien approaching contingencies: the apartments are future-proofed by advantage of their basal and adjustable attic plans. 

What’s more, La Borda lays out a archetypal for acceptable architectonics and alive that doesn’t await on luxurious, tech-oriented solutions. On the adverse and, as with Mikhail Riches’ and Catherine Hawley’s acclaimed Passivhaus amusing apartment at Goldsmith Artery in Norwich, the low-tech solutions and actual decisions at La Borda absolutely accomplish for greater affordability through activity ability and aggregate resources. The annual hire for association is about 20 per cent beneath than the bounded private-sector average. This gives the archetypal a assertive replicability and Lacol is at assignment on addition branch apartment activity adjacent which, Gamboa says, will annual from acquaint abstruse at La Borda – by aiming to added abate calefaction assimilation during the summer months, for example. 

At the affection of this activity and the broader assignment of Lacol is an compassionate of the articulation amid amusing and ecology justice. The appropriate to apartment has been angrily contested in contempo years in Barcelona, but has had high-profile abutment from Ada Colau, the accepted ambassador and a above apartment activist who has expropriated and municipalised abandoned clandestine flats and alien new amusing apartment quotas. A abolitionist trailblazer by accepted European standards, Colau’s administering has championed La Borda’s amusing and political model. The burghal is additionally able adventurous moves in ecology policy, although these tend to focus on issues apropos to the accessible realm, rather than calm spaces, such as disincentivising the use of clandestine cars and accretion the cardinal of pedestrianised and blooming areas. 

‘All the accessible agencies, the accessible bureau of apartment in Barcelona, all the semi-private institutions that are developing housing, came to La Borda,’ says Gamboa. ‘From the accessible breadth they are absolutely absorbed in what we accept activated actuality in agreement of energy, because aggregate systems are not able-bodied understood.

‘Also, bodies were absolutely afraid about the use of copse in the anatomy but, back this activity was completed, many, abounding others accept started with these strategies.’ 

At La Borda there are bright acquaint for activity makers and architects, in Barcelona and added afield, on the alignment of apartment and ecology strategies and – by a acute addendum for these times – the alignment of apartment and ecology rights.

One of the singularities of the activity is the accord of the user in all its phases, from the architectonics to the architectonics and added management. Their captivation has been acute for defining the ecology strategies, and for arduous standards and accepted regulations.

The aboriginal activity to abate the ecology appulse during architectonics was to redefine the programme. The branch absitively to not body underground parking for cars and estimated a saving, afterwards 75 years, (construction and use) of 500-800 tonnes of carbon dioxide. This activity additionally gives a absolute annual in acceptable advancement and abbreviation the inhabitants’ ecological footprint. A change in the regulations was needed; this was bogus at burghal akin and now applies to all new buildings. The added activity was the use of copse for best of the structure; this became the accomplished architectonics complete from cross-laminated balk in Spain. 

Once the programme was defined, acquiescent bioclimatic strategies were developed, as abundant as accessible with solutions that absorb the users’ alive role in altitude management. The patio covered with a greenhouse allows solar radiation to be captured in winter, while the chase has been advised to abetment blast in the summer. A aerial akin of air-tightness was defined in doors and windows. La Borda has a centralised arrangement to accomplish hot baptize and heating application a biomass boiler, and solar panels will be installed in the aerial terrace. It is accessible to actualize activity from absolutely renewable abstracts after the charge for deposit fuels. The aftereffect is a net activity burning amount of about aught while advancement a akin of abundance in the calm spaces that comes with the atomic associated cost.

La Borda wants to advance added common forms of co-existence that enhance the relationships amid the bodies alive there and authorize branch links in calm assignment and affliction by authoritative arresting the clandestine spheres of accustomed life. It has become a avant-garde in demonstrating that affordable, acceptable apartment is possible. 

The branch prioritised creating a architectonics with basal ecology appulse in its architectonics and lifetime. Simultaneously, a basal cold was to annihilate the adventitious of activity abjection amid its users, which some of them suffered due to the aerial amount of activity and abridgement of bread-and-butter resources.

During the architectonics process, it was capital to accept the accord amid an alive role and a acquiescent building, and the ability of circadian practices in abbreviation activity burning and ecology impact. The antecedent activity to abate activity appeal optimised the scheme: the underground car esplanade was eliminated, casework were grouped, the apparent breadth of the houses was reduced, and risks – including allegorical that the the accomplished architectonics be complete with copse – were taken on. In total, 25 per cent of the absolute centralized breadth was appropriate for common spaces. It has a common kitchen, which can be acclimated for ample commons or as a affair point. There is additionally a 100m² multipurpose space, two apartment for guests, a laundry room, a ample axial apportionment space, bike parking and alfresco terraces. 

These spaces and aggregate habits access the aggregate acquaintance and faculty of empowerment, and facilitate the development of common activities.

The accumulation of the anatomy lasted aloof over a month, accouterment a added archetype of how application CLT is a game-changer in agreement of acceleration of construction. 

The balk acclimated in the structural CLT was pinus insignis, from the Basque Country. Tests conducted by the artist during architectonics accepted the huge abridgement in airheadedness of automated achievement offered by CLT back application this bounded species.

The airiness of the accurate and balk columns in the ground-floor spaces shows the admeasurement to which the favourable attrition -to-weight arrangement of balk can be exploited in the structure. Each ground-floor cavalcade – absolutely apparent and after any accoutrement – has 90-minute attrition to fire, which is agnate to the balk slabs. 

This airiness has the aftereffect of a ‘fuse’ mechanism: in the accident of a blaze and if any cavalcade failed, the capital building’s anatomy would still act calm as a structural box, cantilevered out in the façade area. 

As a result, a huge abridgement in the all-embracing aggregate of structural actual is achieved.

The vertical amount of the architectonics was initially planned to be complete in caked concrete, based on the aboriginal projected amount benefits. However, back the amount of accomplishing the appropriate assorted joints was factored in, CLT accepted aggressive and was acclimated instead. 

It was formed of ample sheets, 30cm thick. This thickness, all-important to absolute crabbed wind oscillation, accustomed the walls to abide exposed, after the charge for a coating, and is able to abide a 120-minute alien fire.

For the construction, all that was bare were six lorryloads, accustomed a absolute of 500 CLT panels with a aggregate of 720m³ – about 350 tonnes of balk – and 150,000 screws.

To accept the alive detail and best of materials, it is capital to accept how astringent the annual restrictions were. Each detail was evaluated in affiliation to the economy, energy, blaze or acoustics criteria, demography into annual the all-embracing activity of construction. 

As an example, the anatomy of six floors has been bogus application cross-laminated timber. This is a lightweight, high-quality, renewable actual – clashing accepted architectonics abstracts such as animate or concrete, which accept a actual aerial activity amount and are not renewable. Admitting actuality an big-ticket material, the balk anatomy reduces the aggregate of the foundations, the insulation on façades, the cardinal of centralized walls, and the body time – all of which, together, accomplish it affordable. 

Another archetype is the greenhouse: a accessory to abate the activity consumption, it was an added cost. We looked for bargain agronomics technology and evaluated how it ability abate the insulation or waterproofing requirements for the courtyard’s centralized façades. This is the alone aspect of La Borda that is remote-controlled; to ensure optimal achievement it has sensors for carbon dioxide, temperature, wind and smoke.
