Housing NOW
Myanmar

Myanmar has been experiencing a sequence of overlapping crises for several years. In February 2021, the military coup triggered a nationwide political conflict that rapidly escalated into armed confrontation across large parts of the country. About 120,000 houses have been burned down, infrastructure was destroyed, and large populations were displaced. By 2025, nearly four million people were internally displaced. At the same time, Myanmar has been facing increasingly severe environmental disasters. Cyclones and high-wind events regularly damage rural settlements. In 2024, one of the most severe flood seasons in recent decades affected large areas of the country.

In March 2025, a historical magnitude earthquake, 7.7 on the Richter scale, in central Myanmar. Mandalay, the country’s second-largest city, was heavily damaged. These crises do not happen in isolation. Conflict, natural disasters, economic collapse, and supply chain disruptions interact with each other and compound the housing crisis. In many regions, the reconstruction of a house cannot rely on imported materials, large industrial supply chains, and international contractors. What can realistically be mobilized are local materials, local skills, and local labor. This is the context in which Housing NOW began developing a series of bamboo-based housing systems.

Bamboo does not need to be introduced in Myanmar. It has been used for housing for generations, remains widely used today, and will continue to be used regardless of whether organizations like ours are present or not. It is deeply embedded in local building culture, which means that in many villages, it is still possible to find carpenters who already know how to build with it using established vernacular techniques. That matters for us because our work does not begin from a foreign material or an imported construction logic.

It begins from an existing material culture, an existing labor base, and an existing market. It also begins from a material that remains one of the cheapest available for construction in Myanmar, especially when compared to timber, steel, or concrete. For many low-income households, bamboo is still simply the only realistic way to build. A common assumption in humanitarian construction is that the solution lies in designing one ideal house, a model that can be deployed everywhere. Our experience in Myanmar suggests the opposite. The more a housing system is tailored to a specific situation, the more effective it becomes. Instead of searching for a single universal design, we developed a toolkit of solutions. Today, the work operates through three complementary housing systems: prefabricated bamboo houses, community-driven reconstruction, and an open-source construction manual. Each system responds to a different set of constraints.

The prefabricated bamboo housing system began as a technical experiment. The objective was simple: develop a housing unit that could be produced quickly, transported easily, and assembled by a small team while maintaining structural reliability. Instead of relying on large bamboo culms traditionally used in construction, the system uses bundled, small diameter bamboo. These smaller poles are extremely common on the local market and normally used for fencing or agricultural structures.

A single pole can cost a few cents. Large structural bamboo, by comparison, can cost between $2 to $3 per culm. The idea was to transform this undervalued material into a structural system. Bundles of small bamboo poles are assembled into prefabricated structural frames. These frames interlock to form the skeleton of the house. The geometry distributes loads across multiple poles rather than relying on a single structural element. This prefab system depends on the existence of a production base.

Housing NOW’s workshop infrastructure in Bago City includes bamboo treatment systems, material preparation areas, and prefabrication space and storage. The system did not emerge from drawings alone. Over time, seven full-scale prototypes were constructed and tested in real conditions. Each prototype was tested using a dynamometer. A rope was attached to the structure and pulled horizontally with a truck to simulate lateral loads. These loads represent the forces produced by strong winds or earthquakes. Because the house is rectangular, it was tested in two directions.

On the long side, the structure resisted loads approximately to 330 kilograms, and on the short side, the resistance reached around 250 kilograms before the system began to fail. Interestingly, the bamboo frame itself rarely fractured. The material’s flexibility allowed the structure to deform significantly without breaking. In many tests, the failure occurred at the foundations. The footings were pulled out of the ground and the house tilted rather than collapsing. In one test, the team placed approximately 1.1 ton of bricks on top of the structure and left the load on the frame for about six days. The structure remained stable.

These experiments revealed several important design improvements. Firstly, the size of the bamboo bundles evolved. Early prototypes used fewer poles to bundle. Over time, the number increased until the structure reached a balance between material efficiency and structural resistance. Second, the joinery between bundles improved. Interlocking connections between structural members increased overall stiffness. One of the most important improvements came from modifying the bracing system. Two diagonal braces were connected beneath the floor beam, directly interlocking with each other.

This created a triangular structural geometry that significantly increased stiffness in the middle of the span and reduced bouncing in the floor structure. This incremental process, testing, observing failure, adjusting the design, was done without formal structural engineering supervision. It was a very direct experimental method of engineering based on real-world testing rather than theoretical modeling. Furthermore, over the years, the design of the house evolved. Today, the upgraded version uses timber wall framing instead of a bamboo walling, six-millimeter cement board wall panels instead of a bamboo mat, and a reinforced floor buildup combining bamboo tiles and gypsum board.

In other words, the project did not freeze at prototyping stage. It evolved through direct correction of weak points. The most significant validation of the system came unexpectedly. The 26 housing units project was not initially conceived as a demonstrator project. It emerged as part of an emergency response for families already displaced by conflict. The objective at that stage was not to test the prototype, but to deliver housing quickly, at low cost, and with a system that could be assembled with local participation under unstable conditions.

By that point, the structural system had already gone through multiple iterations across earlier pilot projects. The bundled bamboo logic, the bracing strategy, and the assembly sequence had all been progressively refined through full-scale testing and on-site construction. Twenty-six units marked the first moment where the system was deployed at a larger scale in a real settlement context. In March 2025, a magnitude 7.7 earthquake struck central Myanmar. At that time, the site was located approximately 15 kilometers away from the epicenter.

Some of the houses were already completed, while others were still under construction. After the earthquake, all 26 structures remained intact and fully operational. For a system developed through incremental field testing rather than formal laboratory validation, this event became the most direct confirmation of its structural behavior. It demonstrated that a low-cost bamboo housing system built with local materials and semi-skilled labor could withstand a major seismic event in real conditions.

Today, all units are occupied. These houses are part of an emergency response system, but they are not designed as a short-term shelter. Globally, displacement tends to last for far longer than initially expected. Recent studies indicate that people can remain in refugee or displacement conditions for an average of around 17 years. In Myanmar, the current crisis has already been ongoing for five and a half years.

Based on this reality, the houses were designed with a minimum lifespan of approximately 10 years. With regular maintenance, their lifespan can extend beyond that. The intention is not to provide a temporary fix, but to create a structure that can support families over a significant portion of their displacement period. Today, these prefabricated houses can be assembled in about seven days with small team working together with displaced families. The cost per unit ranges between approximately 1,000 to 1,300 US dollars, the price of a smartphone.

Beyond this initial deployment, the system is being considered at a larger scale. One of the current developments is the construction of a prefabrication warehouse in Bago City using the same structural logic. The building spans 14 meters without intermediate support and uses bundled bamboo members similar to those used in the housing system, but at a larger scale and with increased structural demands. The objective is to move from individual housing units towards a more robust production infrastructure. If bamboo construction is to operate at scale in Myanmar, it requires not only housing design, but also the capacity to produce, treat, store, and distribute materials efficiently. In that sense, the housing system is no longer only a response to emergency condition. It is becoming part of a broader construction ecosystem where material production and design are aligned to support long-term rebuilding efforts across the country.

The second housing system emerged after the earthquake. The prefabricated houses worked well in organized project and displacement camps, but reconstruction across rural villages required different approach. Families rebuilding their homes after disasters rarely want identical houses. Household sizes vary, plots are different, and many families reuse salvaged materials from damaged homes. At the time, mobility across the country had become extremely difficult. Military checkpoints restrict movement between villages, and many young men avoid traveling because of the risk of conscription.

In one reconstruction project, workers trained in one village refused to travel to the nearby village because a checkpoint separated the two locations. They feared being stopped and forced into military service. As a result, a new team had to be recruited and trained locally in the second village. These constraints made centralized construction teams unrealistic.

Instead, the reconstruction model shifted towards a decentralized community construction In this system, houses are being built directly by local villagers. Housing NOW intervenes in three main ways: procurement, funding, and structural standards. The standard reference unit in this post-earthquake model is 15 square meter with a team of five workers, typically four local construction workers and one local supervisor. One house can usually be completed in seven days once materials are available on site. The reference budget recorded for this model is 7,900,000 Myanmar kyat per house.

Procurement became essential because building materials disappeared from the local market after the earthquake. In Mandalay, demand for timber spiked dramatically as residents rushed to rebuild. Instead of buying materials locally, Housing NOW sourced them from other regions of the country. Timber purchased in Bago could be up to five times cheaper than in Mandalay, even after including transportation cost. One element remains consistent across all houses: the raised floor. The house is built on stilts with the living space elevated above ground level. This responds to several conditions at once.

It protects the house from flooding during the rainy season, it improves ventilation and reduces heat inside the upper living space, and it creates a shaded area underneath the house. This typology was not introduced by Housing NOW. It was selected by the communities themselves based on what they already know works in their environment. The overall form follows the local farmhouse logic, a raised dwelling adapted to climate, seasonal rains, and rural patterns of living. This lower level is important in local daily life.

It functions as a way similar to a zayat, a vernacular Burmese resting area used in farm settings during the hottest hours of the day. We have seen this space used by elderly family members to rest in the cooler air below the house without having to remain inside the enclosed upper volume. In some cases, it can also serve as a working space or as shelter for animals. Above, the house itself is not fixed in every detail.

The household and the local carpenter can decide where to place the windows, how large they should be, where the entrances should be located, and how internal partition walls should be arranged. Families can also choose to enlarge the house with their own contribution or build a smaller version and retain the remaining balance in cash. Another detail also comes directly from local construction culture. At the top of the staircase, before entering the house, the balcony handrail is often given a distinct design by the carpenter. This is not something introduced by Housing NOW.

This is a traditional feature found in local farmhouses around Mandalay and in Kachin State, including houses around Indawgyi Lake. This element, like the stilt typology itself, was naturally adopted by the communities for their own houses, maintaining continuity with familiar building practices while integrating the new structural system. The role of Housing NOW in this system is not to replace that language. It is to support it with procurement, funding, and structural standards so that the communities can keep building in ways they already recognize while achieving better structural safety and durability.

The third intervention concerns structural standards. One challenge encountered during construction was convincing local carpenters to include diagonal bracing in the houses. Bracing is not traditionally used in many rural structures, and workers sometimes omitted it to save time or material. However, after witnessing the damage caused by the earthquake, the importance of lateral bracing became clear. The project team insisted that each house include two diagonal braces on each side of the structure to improve resistance against wind and seismic loads. This requirement sometimes required repeated supervision and training, but it significantly improved the structural performance of the houses. Through this decentralized model, reconstruction can continue simultaneously across multiple villages without requiring a centralized workforce.

The third system developed as a continuation of the previous two. As construction became more decentralized, it also became clear that scaling impact through internal teams alone would not be possible. The political situation, mobility restrictions, and overall instability make it increasingly difficult to grow a centralized workforce. If the objective is to reach a large number of households, construction needs to move further away from the organization itself.

At the same time, working closely with communities and carpenters revealed something important. Bamboo construction is already deeply embedded in everyday life across Myanmar. People have been building with bamboo for generations and continue to do so today. One of the main reasons is economic. For a large part of the population, bamboo remains the most affordable construction material available. This means that construction is already happening independently of any external intervention. Houses are being built, repaired, extended, and maintained continuously. The question is not how to replace a system, but how to improve it. The manual was developed in response to this observation.

Over a period of approximately 18 months, Housing NOW compiled a set of targeted improvements that can be applied directly to existing construction practices. The focus is not on teaching how to build a house from zero and not on prescribing a fixed design. It is identifying where small changes can significantly increase durability, structural performance, and lifespan. The manual covers several domains. It includes bamboo treatment methods, joint improvement techniques, structural reinforcement strategies, harvesting guidelines, and also bamboo clump management.

This last component is important because it extends the scope of the construction beyond the building itself. By managing bamboo clumps more carefully, it is possible to both double the quantity and improve the quality of the harvested bamboo over time. Following specific harvesting cycles and maintenance practices, a household can produce more culms from the same plant over a three-year period, while also improving their suitability for construction. This turns bamboo not only into a building material, but into a small-scale economic resource that can generate additional income.

The technical content of the manual is based on a broad collection of references. Innovations were gathered from different regions, including South America and Africa, and combined with local knowledge from Myanmar. These techniques were then filtered based on the realities of the context: limited funding, limited access to materials, and limited access to tools. One of the key selection criteria was that all techniques must be achieved without electricity. Many of the communities concerned have little to no access to power, and this situation is becoming more constrained over time.

All methods described in the manual rely on manual tools and locally available resources. Another important criterion was cost. The manual prioritizes techniques that either reduce cost or introduce improvements without increasing it. In some cases, this involves rethinking materials that are already present in the environment. One example we got from South Sudan is the use of recycled bicycle inner tubes. This can be cut into strips and then used as binding elements for bamboo joints.

Unlike traditional natural fiber ropes, which tend to loosen over time, these rubber strips maintain tension and allow the joints to remain stable despite seasonal changes in humidity. The material is widely available, often considered waste, and can be repurposed at no cost. This approach reflects the overall logic of a manual. It does not aim to replace existing construction culture, but to add value to it through precise low-cost improvements. The manual is intentionally designed as a flexible tool. Each section presents multiple options rather than a single prescribed method. Builders can choose techniques depending on the material available to them, the local condition, and the specific requirements of the house they are working on.

In that sense, the manual is not a design guide. It’s a technical toolkit. The document itself is formatted as a laminated sheet that can be folded and carried on site. It is meant to be used during construction, not studied beforehand. Today, about 2,000 hard copies have been distributed in different regions of Myanmar together with NGOs. The intention is that these techniques continue to circulate beyond any single project. Even in areas where organized construction cannot reach, local builders can continue to apply and adapt these improvements. This is the final step in the process. From prefabricated systems to community-led construction to distributed technical knowledge, each stage moving further towards decentralization. The goal is not only to build houses, but to enable a construction ecosystem that can operate independently under constraint and unstable conditions.

Across Myanmar’s overlapping crisis, conflict, natural disasters, economic instability, rebuilding houses is not a single technical problem. It requires multiple approaches operating simultaneously. Prefabricated bamboo housing allows rapid deployment where organized projects are possible. Community-driven reconstruction enables villages to rebuild autonomously under mobility restrictions, and the construction manual spreads technical knowledge beyond the reach of any single organization. Together, these systems form a toolkit for rebuilding homes in one of the most complex humanitarian environments in the world. And at the center of the toolkit is a material that has been present in Myanmar for centuries, bamboo. Not as a symbol of sustainability, but as a practical material capable of rebuilding homes under the most difficult conditions.

The idea came from a practical constraint. In Myanmar, large structural bamboo is not always available in the right price, quality, quantity, or location. While small diameter bamboo is more accessible and easier to handle. Instead of treating it as a secondary material, we explored how it could be bundled, repeated, and assembled into a stronger structural frame. Bundled bamboo is not new in itself. There are examples in Myanmar and elsewhere where bamboo culms being tied and grouped together for columns, beam trusses, or temporary structures. What is more specific in our work is the use of small diameter bamboo in a prefabricated modular housing frame produced with jigs in Bago, transported to site, and assembled with community participation.

The prefab logic is not unique to Housing NOW. Globally, there has been a strong push towards modular and prefabricated construction from Katerra’s attempt to industrialize housing in the United States to bamboo-specific models such as BASE Bahay and Kawayan Collective in the Philippines. Similar low-cost biomaterial housing approaches are also emerging in East Africa, including Easy Housing in Uganda and EarthEnable. Housing NOW’s system is part of a broader movement, but it is much more context-specific. It was developed for displaced communities in Myanmar during a civil war with extremely small budgets, unstable logistics, import restrictions, and limited access to skilled labor.

So yes, the general logic of prefabrication can spread, but our exact small diameter bundle bamboo system is not a simple open source recipe or something that can be responsibly copied from photos or drawings. The system requires years of prototyping, imported tools, specific jigs, large material orders, and constant micro adjustments at both the detail scale and the full house scale. Some of the tools and materials we used would now be difficult or impossible to import into Myanmar.

For an individual family, the investment in tools, jigs, testing, and fabrication setup would not make sense for a single house. This is why we separate two forms of knowledge transfer. The DIY manual is meant to be open and enabling. It helps displaced families and local carpenters to improve the bamboo house they already know how to build using locally available resources. The prefabricated bundle bamboo system is different. It is an engineered construction system developed through significant research and development, and we are protecting it through patent application in Myanmar. The aim is not to hide knowledge from communities, but to prevent larger construction companies from copying humanitarian research and commercializing it without us.

The manual was researched through a mix of field experience, expert interviews, technical literature, and humanitarian shelter precedents. Some references came from established bamboo sources such as “Towards Resilient Bamboo Forestry” by Arief Rabik and Ben Brown, “Bamboo: The Gift of the Gods” by Oscar Hidalgo López, and the humanitarian bamboo guidelines developed through the Humanitarian Bamboo Project by Dave Hodgkin and Humanitarian Benchmark Consulting. Other details came from the field innovation rather than conventional bamboo textbooks. The South Sudan inner tube detail, for example, came from the flood resilient shelter research developed by Medair with EPFL’s Structural Xploration Lab.

That project combined computational design, local material prototyping testing, and field workshops for flood-affected communities in South Sudan. A lot of useful humanitarian construction knowledge is not well indexed online. It often exists in prototypes, NGO reports, workshop documents, field tests, local improvisations, or conversations with practitioners. So when a method does not appear clearly on the internet, it does not mean it is invented. It may simply never have been turned into a researchable technical standard. For our manual, we did not copy random techniques. We cross-checked ideas against bamboo construction logic, local material availability, cost, ease of use, and whether a carpenter in Myanmar could realistically apply them. The manual is hands-on because the audience is hands-on.

We are currently working across several directions. Housing NOW has completed three bamboo clinic projects, one in the Burmese Himalayas on the outskirts of Puta-O, one in Yangon slum of Hlaing Thar Yar, and one in Thanlyin Township, south of Yangon. Together, these clinics support healthcare programs treating HIV, tuberculosis, malaria, and mosquito-borne diseases with an expected capacity of around 200,000 consultations per year. We are also building an ECCD center in a slum south of Yangon, combining bamboo architecture, playground design, and community infrastructure for children and caregivers.

In Bago, we are developing our prefabrication workshop, a large-scale bamboo structure that pushes our small diameter bundled bamboo technology to a new level. It is not only a workshop, but a piece of experimental engineering and an architecture developed through years of research, structural testing, and full-scale prototyping. Once completed, it will allow us to increase the production of prefabricated low-cost housing units for IDP camps in Myanmar. In parallel, we are developing BentShelters, a modular bamboo community shelter system derived from the mathematical research of Alain Lobel in the 1990s.

The project resolves a complex geometric problem through repeatable joint and identical bamboo members, allowing the system to be prefabricated, transported, and assembled with a high level of quality control. The ambition is to create a three-dimensional catalog of deployable shelters, classrooms, kitchens, meeting space, and community structures that can vary in shape and scale while remaining based on the same modular logic. Looking ahead, we want to take what we have learned in Myanmar into new contexts. We are now exploring opportunities in Uganda, Bhutan, Kenya, India, and Ghana, especially with low cost, bio-based, and locally buildable construction systems could support housing, school, clinics, and community infrastructure.
