Over 1 million people in Nicaragua are homeless. KuNa, in Mayan “House of Nature”, is a bamboo social housing program managed by the communities of Chontales, Salinas de Nahualapa and El Astillero. 
Our mission is to create a bamboo based economy that empowers the community to design and build their own homes using local, regenerative and high performing materials. In 2021/2022, the NGO Casa Congo launched KuNa and built the first 21 bamboo homes.

Introduction
After Nicaragua was struck by two category four hurricanes, Eta and Iota, tens of thousands of people were left with almost nothing. These hurricanes from late 2020 highlighted a broader issue around Nicaragua’s housing crisis, which counts over 1 million people living without adequate shelter and with less than $3/day.
In this challenging context of climate disasters and poverty, there is hope: bamboo. Bamboo has over 1,500 different species and two of the strongest types (Asper and Guadua) are abundant in Nicaragua. Aside from bamboo’s ability to sequester carbon, grow rapidly and enhance ecosystems, bamboo is also an incredibly versatile building material. 
Before initiating the design and planning of KuNa, the project team conducted multiple surveys with local community members and the architecture was defined through a participatory design process.
Casa Congo partnered with ANF and INVUR to introduce guadua bamboo to the local building code and approve its utilization for social housing, which had typically been delivered out of less sustainable traditional building techniques. MARENA (local ministry of environment) was a key stakeholder to support KuNa due to the decarbonization potential of bamboo homes compared to traditional ones. 
The first 21 beneficiaries to receive a KuNa home were selected within El Astillero based on poverty thresholds and family requirements, with a view to then scale the program in the following years to end the housing crisis in this village.

Impact
KuNa’s mission is not to give homes to communities in need, it’s to give communities the skills and tools to build their own homes sustainably in the long term. 
Given Nicaragua’s lack of infrastructure and industry around bamboo, KuNa’s first step was to establish the country’s first complete bamboo supply chain – from farm to wall. The key to KuNa’s success revolved around the team “Construyendo Suenos”, which comprises of over 70 farmers, carpenters and project beneficiaries who rallied together to make their dreams come true. 
We trained farmers in the Chontales region to improve the forestry management of 6 hectare of bamboo and established a salt based treatment centre with the community of Las Salinas of Nahualapa, where we leverage ocean tides to fill natural salt pools and cure bamboo. We trained a team of carpenters and built a prefabrication workshop and storage shed in El Astillero, where the dried bamboo is sorted in sizes and then transformed into modular panels following a series of standardized steps (150 poles / home).
So far, KuNa has given a home to 21 families in need and its impact in terms of long-term education and capability building is significant. Having a safe and well-designed house is a life changing asset. 
Thanks to a collaboration with a student from the Polytechnic of Milan, each KuNa house will also have an agroecological garden with medicinal plants, food and water management systems. 
So far, Kuna has indirectly impacted around 1000 local people and set a new case study for bamboo social housing in Nicaragua.

Core team
KuNa was a truly multi-disciplinary and international team effort that involved many private and public organizations. 
The project was initiated and lead by Sol Rodriguez and Nicholas Kaspareck, co founders of Casa Congo and respectively an engineer specialized in mass timber and an architect experienced in sustainable development.  Manuel Cortez, school director of Casa Congo, and Guillermo Lopez, El Astillero's best builder, ran the project locally and oversaw logistics.  
Casa Congo formed a team of carpenters comprised of local men and women who saw KuNa as an opportunity to learn about bamboo. This team later self proclaimed themselves as “Equipo Construyendo Suenos” – the Team Building Dreams.
A critical part to the mission was the arrival of Don Oscar Ruiz. Don Oscar is a Colombian farmer with over 40 years of experience in bamboo silviculture who came to Nicaragua to train the farming cooperative in Chontales and handover his knowledge to Dona Rita, who lead the local bamboo harvesting efforts.
Jaime Pena, founder of Arquitectura Mixta, volunteered his time to design KuNa and then introduced Tacuara, a Colombian bioconstruction collective. Uraba Ponzone lead Tacuara’s team of bamboo masters in Nicaragua for three months and trained the local community in bamboo carpentry and prefabrication. 
From the other side of the world, Francesca Aiuti, an intern from the Polytechnic of Milan, designed the KuNa agroecological gardens and handed a playbook over to the families.
Many more organizations and individuals were part of this epic effort - it really does take a village!

Where are we now
KuNa was launched in March 2021 and achieved practical completion on September 30th 2022. So far we have:
  • Trained 70 farmers and carpenters in bamboo silviculture and construction
  • Established a bamboo pilot plantation 
  • Built 1 prefab workshop and storage facility 
  • Built 1 temporary treatment and drying facility
  • Integrated guadua bamboo in Nicaragua's building code
  • Sunk 40 tCO2e 
  • Built 21 homes 
We've established a complete value chain, from farm to wall and the local community now has the tools and skills to procure bamboo and build more homes independantly.
An indication of our team’s capacity:
90% funding already raised
100% expertise already found
50% materials / equipment already found
100% builders already found
Finance: € 77,500
Following the first pilot, KuNa is now a project ready to be replicated and improved. However, due to budget and timing constraints, KuNa does not have an ideal prefab workshop and lacks enough tools / equipment to truly scale the program in El Astillero. Our request for additional funding would be primarily channelled towards upgrading our workshop and purchasing more power tools.
  • New flooring for workshop
8,000
  • New roof with raiwater collection system
12,000
  • Photovoltaic panels and battery system
45,000
  • Equipment and power tools
10,000
  • Land concession for workshop (5 years)
2,500
Skills: Planning & Management
As a final contribution of expertise, KuNa requires an expert in managing workshops and production facilities to train 1 - 2 community members of El Astillero to be the KuNa workshop managers. This would include empowering the local team with skills and tools to perform inventory controls, workflow management, PMP’s and other best practice SOP’s to run a bamboo workshop of this kind. Ideally this person can also supervise the launch of new bamboo initiatives such as furniture making.

Hands
The first iteration of KuNa has been entirely focused on the bamboo architectural structure and electrical / hydraulic systems. It would be of real value to have volunteer architects and builders focused on creating bamboo furniture, also leveraging the bamboo offcuts. Many women of the local community have expressed a desire to learn how to make bamboo furniture – either to furniture their new KuNa homes or to sell and make Astillero into a bamboo craft village.
