Where are we now
The multidisciplinary team of the PHF has been working in Corralones since 2020 together with the community, achieving in a first time a photogrammetric survey and a participatory diagnostic and mapping of the neighbourhood. From this diagnosis emerged the need to generate quality public space and to requalify and expand the existing community centre. Through a participatory workshop, a programme of needs was drawn up and a project proposal was developed for both the external and internal spaces. Thanks to a small amount of funding that was secured in 2021, it was possible to implement the requalification and reforestation of the external space, including a small place and a playground.
An indication of our team’s capacity:
50% expertise already found
30% materials / equipment already found
60% builders already found
Finance: € 15,000
The Corralones Community Learning Centre project is part of a multi-scalar, participatory and actor-driven process. The funding’s request of 15’000 € corresponds to the 50% of the estimated construction cost through the acquisition of the principals construction materials, which will serve as a trigger to create a generator of opportunities and exchange for the community.
50% of the funding will be covered by the community as a counterpart with constructions materials and qualified and no qualified labor force through the community work. The team of the Pro-Habitat Foundation also enters as a counterpart with human resource, especially with the design process and the construction supervision.

Skills: Technique, Financial advice, PR & Marketing
Financial advice
We would be really glad to obtain advice on financing possibilities to make the project real, due to the limited economic resources of the community.
Techniques
The project contemplates walls made of Compressed stabilized Earth Blocks (CSEBs) with lime, that have been developed in collaboration with the Faculty of Architecture and Habitat Sciences of the University Mayor of San Simón. We would very much like to be able to exchange with experts in order to improve and optimize its characteristics and the production process.
PR and Marketing
We would very much like to strengthen our communication capacities in order to strengthen networks and partnerships.

Stuff: Materials, Equipment & tools
We currently have a Cinva-Ram machine for the production of Compressed Stabilized Earth Blocks. However, we have seen the need to optimize the production process, as most of the process is done manually, which makes the process very time consuming. In order to be able to replicate the use of this ecological material with the Corralones Community Learning Centre project, it would be very useful to have the following equipment available:
- Compulsory Mixer: approx. USD 2.500, which would speed up the grinding and mixing of soil and clay.
- Optimized Cinva-Ram: aprox. USD 600. The cinva-ram currently available is a prototype that needs to be improved for higher strength and faster production.

Hands
The exchange and collaborative work that is generated between practitioners, the community and the Pro-Habitat Foundation team is very important to generate sustainable processes and collective learning among all actors.
We always work really well together with local and international volunteers and interns and will be very pleased to collaborate with new one.
For this project we would need volunteers to support the final design process (architecture and engineering) as well as the construction process, e.g. for the production of the Compressed Stabilized Earth Blocks, wooden structure assembly, etc. They will integrate our multidisciplinary team and work together with the community.
