General information
The architecture studios Arqbag cooperative and Edra architecture km0 together with the construction company Coeco cooperative starting a new project, the consultancy and prefabrication of construction products of raw earth and with the focus on reducing emissions from the construction sector and generating new decentralized employment opportunities. The protagonist of the project: construction with earth.
Catalonia has a long tradition of construction with earth, from Ponent to the Empordà, however, the industrialization of construction materials has eclipsed the traditional techniques such as construction with raw earth. So, could we recover the earth as a building material adapted to the current needs?
Construction with raw earth has many benefits for the habitability of the spaces around us. It is not only a material that allows structural walls to be made, but that, due to its mass, has a lot of thermal inertia, which means that it stores heat in winter (and gradually releases it towards the interior regulating the temperature), as well as in summer the heat stored in the wall during the day is released to the outside with the freshness of the nights. In addition, it has the ability to regulate the humidity of spaces and to breathe. That is why earth is conceived as one of the healthiest materials for construction. The earth is compacted humid, and when dry, it raises great resistance and hardness, which also protects itself from the rain and wind.
The land is revalued when contacting waste management companies, with a clear commitment to circularity and low environmental impact. It is mainly a raw matter and, therefore, not cooked, with the energy saving and the null contamination that this entails. Finally, a prefabricated system is proposed that allows us to improve working conditions and have greater control of costs and deadlines at the time of execution of the work.
The commitment to prefabrication is crucial for the updating of traditional, conscious and responsible techniques with the climate context and proximity resources. The fact of opting for the industrialization of the earth has a primary objective: to ensure that its qualities can be available to more people and that the material is a competitive alternative to the current construction systems, both at the cost level and at the speed of construction. In this way, it is intended to achieve a catalog of options of low environmental and healthy impact construction materials at everyone's reach.
Main features and goals of the crowdfunding campaign
Our goal is to be able to produce large format compacted earth prefabricates. We have the expertise of a team that has been working with the earth for more than 20 years, studying its structural, biological and environmental qualities, and developing a feasibility plan and business model that not only offers a healthy and safe product to the market but is able to generate a network of decentralized jobs.
Now is the time to start the project, and that is why we need to generate the infrastructure, update the regulations of the construction sector and disseminate these new (or not so new) ways of building:
– low impact at adjusted prices – popularizing low environmental impact construction and dissociating the concept of sustainability of products accessible to a minority of society, can be achieved thanks to the industrialization of the system, reducing a hard labour derived from the current manual process to achieve rammed earth elements and being able to increase its production.
— circularity — to ensure that a large part of the raw material we use in the construction world comes from prior waste management instead of using extraction material. To take away from the earth the label of “waste” and to put on it that of “resource” is one of the social needs that our product aims to cover.
And this is how we want to achieve it:
1—the raw material is obtained from excavation companies and waste management companies. The earth they currently receive is reused only to cover and naturalize old landfills, this project gives it value and makes it another resource.
2—we place the epicenter of our production in the city of Balaguer, where we have a warehouse where we can store the earth and manufacture the parts on demand. The strategic position of the factory allows us to cover a large amount of the territory and reach projects within a radius of 200 km, an optimal distance to maintain the low environmental impact of the product.
3—we offer as a technical office two services to be able to implement this system. A first comprehensive service of drafting the entire project (architectural, accompaniment, and environmental advice); and the second, the adaptation of the construction system to projects that want to opt for prefabricated earth as construction material, promoted from a owned meterial laboratory.
4—the construction of the prefabricated structure of rammed earth is carried out with the own means and personnel in our facilities.
5—the finished product has a last warranty and maintenance service.
Why this is important
The national and European environment increasingly tends to the implementation of regulations and guidelines that lead us towards a construction of low environmental impact, industrialized and with products and materials that meet high requirements of circularity. In this present and immediate future is where we detect the opportunity to generate a product that helps us to make this transition process towards a more conscious construction with the environment that surrounds us.
With the common objective of contributing to the decarbonization of the construction sector and the generation of quality and decentralized employment, the industrialization of compacted earth is an essential solution, since another great interest of the land are its almost zero CO2 emissions, a global objective to make a transition towards decarbonization through models, materials, systems and technology that can make us more resistant to these future conditions, and do so at the same time with proposals that take into account the low environmental impact and the health of people.
Arqbag is a young architecture studio that began its activity in 2013, and was formalized as a non-profit cooperative in 2017. Since the beginning they have maintained a strong link with the university (ETSAV – UPC), establishing their workspace in the same campus where they trained, as well as the collaboration and leadership of subjects and projects that are developed, a constant contact with research and innovation.
Its activity is articulated through three complementary vectors: social, environmental and material, through three lines of action within the cooperative: participation, environmental consultancy and architectural design.
It is a company positioned in the sector as an expert in technological innovation thanks to its direct contact with the Polytechnic University of Catalonia. They develop and advise energy efficiency and low environmental impact projects in the construction sector.
Edra arquitectura Km0 is an architecture studio specialized in efficient and low environmental impact architecture that was born in 2003 rooted in Ayerbe, a town in the province of Huesca. Edra works in all the Catalan and Aragonese provinces participating in the development of rural areas and their communities, from a global and sustainable vision, focused on comfort, energy efficiency and design with local materials and low ecological footprint. She has a research experience from the EdraLab laboratory itself develops materials based on soil and natural fibers that she implements in her projects.
It is a company positioned as an expert in projects and construction works with earth within the construction sector. In addition to developing them, it also advises energy efficiency and low environmental impact projects built with earth.

Coeco is a family work cooperative created in 1980 and constantly evolving. They are dedicated to the world of construction, restoration and facilities of all types of buildings.
They believe in the combination of Mediterranean wet constructions and Central European dry ones to carry out efficient projects, respectful of the environment and the health of people. In this sense, they are always open to combining different techniques and solutions in each project, betting decisively on combining earth and wood in the same project.
It is a company positioned in the sector as an expert in bioconstruction, developing works with natural materials such as earth and wood. They have built projects of all scales with these types of materials.
Arqbag and COECO, we have participated jointly in the SAVASCO project co-financed by INTEREG POCTEFA (to find constructive solutions based on the reuse of agri-food waste from the cultivation of corn and sunflower, through a transversal team France - Andorra - Spain). And together with Edra, they have carried out a Singular Project for the research of construction with prefabricated earth at the national and European level until the definition of Crua.

Social commitment
Agrorural development
We look at the rural environment, which has been systematically devalued and deprived of infrastructures and services as a result of an excessive vision of the city, which has accentuated and aggravated its progressive abandonment and depopulation.
Therefore, it seems strategic to explore the possibilities of rethinking, reorienting and relocating economic activities also in the primary and industrial sectors towards a perspective of proximity, with low energy content and at the same time allowing the activation and networking of the whole territory.
