Welcome to CO-HAB/RAVAL!
We are a team made up of two engineering and architecture research groups from the Universitat Politècnica de Catalunya (REARQ-UPC and GICITED-UPC) and the Oasiurbà association (a group working towards social transformation through housing in the Raval neighbourhood).
We encourage you to take part in the CO-HAB/RAVAL project. Its main goal is to improve quality of life for inhabitants of the neighbourhood through the co-design and co-construction of small renovation projects in collaboration with local associations, neighbours and professionals.

Method and work phases
Guidance and participation
This phase includes a wide range of participants: UPC researchers, NGOs, neighbourhood associations, residents, local businesses and representatives of local administrations.

The co-design phase involves the selection of spaces and working areas, the pre-selection of pilot buildings, participatory sessions and the preparation of a catalogue of micro-projects.
6 working areas for use in the second phase are chosen.
1 - Habitability and healthiness
2 - Security
3 - Resiliency
4 - Inclusion
5 - Sustainability
6 - Health
Inner courtyards for ventilation and illumination (finishes, lightwells, pest management, etc.).
Electrical installations (circuit breakers), fire load, combustible materials, lessons on serious structural damage and signage.
Construction or redistribution of mobile elements (furniture that can be used for work from home or storage in common spaces).
Signage or support elements, small interventions for improving accessibility (portable ramps, railings, signage).
Thermal insulation for interior spaces, support for the thermal performance of windows and doors, solar protection (weather stripping, double glass, etc.).
Training on healthy usage habits, community management and use, conservation and maintenance of spaces and new or existing constructive systems (ventilation, solar protection, humidity regulation, conflict management, compatibility and management of turns and usage times).
Results and replicability
A shared, participatory database. Mapping and prioritization of a selection of cases where intervention is needed.
Co-design of a catalogue of micro-projects
Collaborative preparation of a catalogue of micro-projects for the renovation of residences and shared spaces in the Raval neighbourhood. These micro-projects can also be applied to other areas of Barcelona’s old city. Specific proposals for each of the six working groups + full projects.
Implementation of 8 prototypes
Co-construction and collaborative implementation of eight prototypes in pilot buildings.
Collaboration methods and networks
The proposed method is a result in and of itself: it promotes the creation of long-lasting collaborative networks.
Impact on the environment and
The prototypes address the health problems present in old buildings, such as foul smells or excess humidity due to a lack of ventilation. These solutions are also designed to be environmentally sustainable, with the generation of new forms of ventilation using passive, natural systems.
It has been shown that quality of life improves when neighbours see themselves as part of a community; this is particularly true for disadvantaged neighbourhoods. Shared areas like rooftops can serve as gathering spaces that help to forge connections among residents.
Our prototypes also promote a local, circular economy. All prototypes were made with support from small, local businesses to ensure they can be manufactured in the neighbourhood.
