From Hostel Room Model to 1500+ Foldable Buildings: IIT Grads Build Infrastructure That Travels

A foldable building is a structure designed to travel in a compact, folded form and become usable after reaching its destination. This matters when people need shelter or healthcare quickly, especially where transporting bulky construction materials is difficult.

The article gives one clear example: Modulus developed MediCAB as a portable healthcare unit. It could be configured for screening, isolation and intensive care. A unit was deployed in Wayanad, Kerala, in 2020, with support from Habitat for Humanity. The excerpt states that it could be transported in folded form, but does not describe its hinges, panels, joints or assembly sequence.

The broader idea is speed and mobility. Instead of waiting years for permanent construction, organisations can move a prepared structure to a site and open it there. This can help remote communities and crisis-affected areas. However, the supplied excerpt does not provide enough technical detail to explain exactly how Modulus assembles its foldable buildings.

The article excerpt does not state how many foldable buildings Modulus Housing has built overall. It therefore cannot support a reliable total. Giving a number would go beyond the available information.

It does identify one specific deployment. In 2020, Modulus sent a MediCAB unit to Wayanad, Kerala, with support from Habitat for Humanity. The unit was designed for portable healthcare and could be configured for screening, isolation and intensive care. Earlier, the company had also made portable cabins for construction sites and migrant workers.

The excerpt describes Modulus working across disaster response, construction and healthcare. It does not provide a complete list of locations or a final count of buildings. It also does not mention the schools, anganwadis or agricultural shelters named in the question. Those details would require additional source material beyond this excerpt.

The 2015 Chennai floods exposed a long gap between emergency relief and permanent housing. Shreeram Ravichandran saw families near Chennai’s OMR and ECR lose thatched homes, belongings and living space within hours. Relief arrived quickly, but rebuilding could take years. He began asking what families could use during that transition.

At IIT Madras, Shreeram and his childhood friend P Gobinath studied the aftermath of the 2004 Indian Ocean tsunami. They found that families might receive tents or tarpaulins within days, while permanent homes could take five or even ten years. In Gobi’s hostel room, they experimented with cardboard and thread to develop a sturdier shelter.

The Centre for Innovation gave them Rs 50,000, and Nirmaan later provided Rs 2 lakh. After graduating in 2018, they committed full-time to the idea and started Modulus Housing. Their original disaster-shelter problem became the foundation for portable buildings.

When emergency relief arrives quickly but permanent housing takes years, communities face a dangerous transition. Families may receive food, water, tents or tarpaulins, yet still lack a durable place to live. The immediate crisis may end, but daily uncertainty continues.

The Chennai floods made this visible to Shreeram. In settlements between OMR and ECR, thatched homes and belongings disappeared within hours. He contrasted those families’ experience with his own: his neighbourhood had power cuts and food interruptions, but his building remained standing. For affected families, he said, the land had become empty.

The article connects this problem to earlier tsunami rehabilitation. Temporary shelters might last only the first 30 days, while permanent homes could take five or ten years. That gap became Modulus’s original problem statement. Portable buildings were meant to offer a sturdier bridge between immediate relief and permanent housing.

Portable buildings occupy the space between emergency shelters and permanent buildings. Tents and tarpaulins can provide immediate cover, but the article presents them as short-term solutions. Permanent houses offer a lasting settlement, yet rehabilitation may take several years. Portable buildings aim to address the long period between those two points.

Modulus began with the question of whether it could build something sturdier than a tent, quick to transport and easy to open at the site. The founders linked this need to families who might wait five or ten years for permanent housing. Their goal was not simply faster relief, but a more usable structure during the transition.

The excerpt does not state the precise materials, lifespan, cost or weather performance of Modulus buildings. It does show the operating difference: tents or tarpaulins arrive early, permanent buildings arrive later, and portable structures are designed to move and deploy between those stages.

Modulus moved beyond disaster shelters because disaster demand could not be planned reliably. Shreeram recognised that being prepared for disaster was itself a luxury, while communities faced everyday infrastructure problems. The company needed a practical use for its technology between emergencies.

It began making portable cabins for construction sites and migrant workers. This work generated revenue after roughly a year and a half without it. It also showed the founders that portable buildings could help in rural and remote places, where good materials and skilled labour were difficult to obtain. Their vision therefore expanded beyond post-disaster buildings.

The team later explored portable healthcare infrastructure with SELCO Foundation. During COVID-19, hospitals needed beds and isolation spaces quickly, leading to MediCAB. The supplied excerpt does not explain Modulus’s work with schools, anganwadis or agricultural shelters, but the broader pattern is clear: reuse the same portable-building approach for recurring needs.

Reusable, movable infrastructure is valuable when a place is remote, temporary or affected by crisis. The structure must travel efficiently, reach difficult sites and become useful without a long construction process. Reuse also allows one design approach to serve changing needs, such as shelters, cabins or healthcare spaces.

The article identifies three practical principles behind Modulus’s approach: the building should be sturdier than a tent, quick to transport and easy to open at the site. The founders also focused on places where construction is hard because materials and good labour are scarce. MediCAB applied the same portable-building idea to screening, isolation and intensive care.

The excerpt does not explain the exact engineering details, such as connection systems, structural materials, folding geometry or transport dimensions. It does show the larger mechanism: prepare a movable unit, take it where needed, configure it for the task and avoid rebuilding everything from scratch.
