Collecting rather than extracting: is this possible for architects?
An aluminium façade that reflects the sky with perfect precision reveals nothing about where its material comes from. A polished stone floor rarely evokes the image of a quarry. Concrete appears neutral, detached from the landscapes it exhausted in order to exist. Timber once existed as part of a living forest, not as a wall.
The violence of extractive architecture often becomes invisible once materials are transformed into clean surfaces and finished buildings. Buildings appear static and permanent, yet they are produced through globally dispersed systems of extraction, labor exploitation and environmental degradation.
Post-extractivist architecture is a fundamental shift in how architecture relates to materials, labor, ecology and time: from domination and consumption toward practices of collecting, care, regeneration, temporality and material awareness.
What is the hidden foundation of architecture?
Modern architecture, despite its progressive image, remains deeply dependent on extraction. That is the process which truly makes construction possible beyond drawings, concepts and visual representations.
In its simplest form, extraction refers to the removal of something and someone claiming it for utilisation elsewhere. Extraction typically refers to material things, from rock, ore, minerals to oil, gas and water.
Almost everything we do, build and consume is linked in some ways to processes of extraction. Building shelters, growing food and clothing ourselves are all material-extractive processes. These imply also seemingly less material forms of extraction, which are energy, labour, time, value or knowledge and it can be human, non-human or non-living.
If extraction, at some level, is essential to the maintenance of life, it becomes extractivism. It is not enough to say that extractivism is anthropocentric, it is capitalocentric. Extractivists, capitalists and colonists share the same ideology of exploitation.
The term extractivism is used to refer to the violent ideology of appropriation underlying much of late capitalism. It is more than just a physical process and includes not only resources, land and infrastructure but also knowledge, labour, culture, policy and economy. These conditions are fundamentally bound up with architectural production, but are often dismissed as being outside of the realm of architectural practice.
On top of that, the promotion of technological innovation has supported our continuously striving for a future in which humans will unquestionably flourish. The assumption of such a future as inevitable, underlies many of the forms of architecture in modernity, feeding our confidence in mastering planetary resources and systems.
This approach to technological capacity has meant that we have constructed nature, material and living, as something external to ourselves and in service to us, rather than intrinsic to our own humanity and actions.
This anthropocentric understanding of nature has long shaped legal, economic and architectural imaginaries. Christopher Stone’s provocative question Should Trees Have Standing? challenges precisely this logic by asking whether natural entities should be recognised as subjects of rights rather than passive resources available for human appropriation.
Is this constructed fact guiding our practices and our perceptions of the world we are living in?
Across the Global, landscapes rich in minerals, forests and water have become arenas of contestation, where local communities face displacement, pollution and the erosion of traditional livelihoods. The expansion of extractive frontiers, driven by global demand for energy and raw materials, has not only intensified socio-ecological inequalities, but also reconfigured the logic and emotional worlds of those affected. These tensions, visible from Latin America to Southeast Asia, show how ecological degradation and social and environmental injustice are deeply intertwined.
Sometimes these consequences are the direct result of apparently noble aims, from enabling greater efficiencies in food production to reducing energy use in buildings via new oil-based insulation products and sealants. But as a toxic by-product of mining rise to the surface many years later in South Africa, chlorinated pesticides are being identified in breastmilk from mothers in India, or adhesives, flame retardants and surface coatings disrupt our bodies’ endocrine and reproductive systems, we realise these ”solutions” create as many problems as they solve.
Architecture, in this context of the emergence of unexpected consequences, must begin to repair, rather than continue to deepen the existing damages.
But can architecture even exist without relying on systems of ecological depletion and colonial extraction?
In modern times, we speak a lot about building sustainable architecture, while continuing to compromise the ability of future generations to meet their own needs, by depleting and damaging resources.
Post-extractivist architecture is not merely a sustainable version of current building practices. It demands more than greener materials or efficient technologies. A post-extractivist architecture could be understood as a shift from extraction toward collecting: a practice grounded not in the continual consumption of new resources, but in the careful reuse, transformation and reinterpretation of what already exists. Collecting thinking transforms architecture from an industrial practice of consumption into one of curation and ecological attentiveness.

It is necessary to make a shift towards collecting inherited matter, existing buildings, embedded histories and already-formed relationships rather than seeking value primarily through the extraction of new resources.
But how to make this shift? Would it be possible for architects?
Drawing out architecture’s relations with extractivism, not only as a related function but as an ideological position that is deeply ingrained in architectural production, is a starting point for real alternatives. These alternatives are already present in many existing practices that face up to the specific conditions of extractivism from which they emerge, showing how identities formed during extractivism can be transformed afterwards, within and through architecture.
Yet these transitions cannot be reduced to technical solutions alone. Simply substituting concrete with bio-based materials or replacing fossil energy with renewable systems does not necessarily dismantle extractive logic. The transition toward green energy itself depends upon new forms of mineral extraction, revealing how sustainability can sometimes reproduce the very systems it seeks to overcome.
From this perspective, the challenge is not simply to identify less harmful materials, but to reconsider the value framework underlying architectural production itself. As John Baird Callicott argues in environmental ethics, nature cannot be reduced solely to instrumental usefulness; it may possess value in and of itself. A collecting architecture therefore requires more than technical optimisation: it implies a different ethical relationship to matter, ecosystems and living environments.
Sophisticated reuse projects that subvert the unidirectional nature of extractivism, such as upcycling secondary materials to produce new building components, seeing buildings themselves as material banks or designing for deconstruction, represent a shift in architectural practice towards recognising and actively intervening in the material and other networks within which architecture is embedded.
Contemporary construction does not simply transform the site on which architecture appears. It reorganizes territories, ecologies and economies that often remain geographically absent from the finished project. Quarries, forests, extraction zones, industrial plants and transport infrastructures become silent extensions of architecture itself. A collecting perspective therefore requires a collapse of these mental distances.
Construction does not simply consume materials; it reorganizes territories, ecologies and economies. We have to learn to collect their histories and trace their future. This perspective requires architects to redraw the boundaries of the project itself.
Once architecture begins to trace the hidden histories embedded within construction, the assumption that resources must always be newly extracted becomes increasingly difficult to sustain. The built environment itself begins to appear differently, not as a collection of finished objects, but as an immense reservoir of latent materials, energies and possibilities.
If extraction has long depended on the continual search for new resources, collecting begins from another assumption: most of what architecture needs is already there, in one form or another.
Existing buildings, abandoned infrastructures, demolition waste and overlooked local material streams contain latent resources that too often remain invisible within conventional construction practices. In this context, architecture no longer asks only what can be built, but what can be recovered, transformed or reinterpreted. Reuse, salvage and urban mining do more than reduce material consumption; they challenge the linear logic through which buildings are produced, consumed and discarded. Collecting discarded materials changes not only material flows but also architectural authorship and values. It transforms architecture from an act of consumption into an act of curation.
Modern architecture has often pursued permanence through stability, imagining buildings as fixed forms capable of resisting change. Contemporary realities, such as climatic instability, evolving social needs, technological transformation, continuously challenge this model.
Stewart Brand’s observation that buildings continuously “learn” through adaptation, maintenance and changing use directly challenges the modern image of architecture as a fixed and completed object. From this perspective, durability may reside less in permanence than in a building’s capacity to transform over time.
A collecting architecture may therefore require another understanding of durability: not permanence, but transformability. To build transformable is not simply to anticipate future modifications; it is to recognize architecture as an ongoing process rather than a completed object. Buildings must be capable of collecting changing uses, behaviours, technologies and contexts throughout their lifespan. In this sense, adaptability becomes a form of material care. By extending relevance beyond initial construction, architecture preserves embedded resources and shifts from a linear cycle of replacement toward a circular process of continuous negotiation with change.
Already in the eighteenth century, Jeremy Bentham proposed a displacement of moral attention away from rational capacity toward the capacity to suffer. Although formulated in relation to animal ethics, this shift resonates unexpectedly with contemporary ecological questions. A collecting architecture might similarly require an expansion of architectural concern toward the often invisible consequences of construction, toward damaged landscapes, vulnerable communities and more-than-human environments affected by architectural decisions.
Collecting requires a transformation in how architecture understands its own role. The architect can no longer operate exclusively as a heroic producer of new forms or a master planner imposing order from above. Instead, architecture begins to resemble a practice of assembly, negotiation and care by collecting relationships, local knowledge, existing resources and long-term consequences.
Such a shift also depends upon institutional and political support, capable of encouraging circular practices and discouraging extractive forms of production. Without this broader transformation, collecting risks to remain a marginal strategy rather than becoming a genuine architectural paradigm.
Perhaps, it would be time to realise architecture is not only what is built, but also what is set in motion
What becomes increasingly difficult to ignore is that architectural decisions are never neutral or isolated. They participate in wider systems of transformation that shape both present and future conditions of life. The materials we choose, the buildings we preserve or demolish, the resources we consider available or disposable, all of these decisions extend beyond their immediate context.
Our present architectural choices shape futures we cannot fully anticipate, but are already producing. Every decision made today participates in shaping conditions that may become irreversible tomorrow, whether in terms of ecological stability, material availability or the possibility of inhabitable environments. This does not place architecture in a position of control, but rather in a position of responsibility that is often larger than it appears.
Perhaps what is at stake is not the possibility of making a perfect shift away from extraction, but the recognition that such a shift is already being negotiated, partially and unevenly, through every architectural act. Whether this negotiation leads toward repair or further degradation remains open. What is certain, however, is that architecture is never only about the present moment of construction. It is always already an intervention into futures that are still unfolding.
