In 2015, “3D printing” still conjured up images of the absurd, the novel or the futuristic — think custom tabletop game pieces, small replacement parts, decorative novelties and even 3D-printed chocolate.��

But��Maggie Grout (Mgmt’21) has never been one to think small. At just 15 years old, three years before she enrolled as a Buff, Grout walked up to her dad and asked a life-changing question: “What if we 3D-printed a school?”��

The answer, in the form of Grout’s nonprofit��, would ripple out to impact not only her own future, but the futures of families and communities across the globe.��

Welcome to Bougainvillea��

In 2022, seven years after Grout’s initial idea sparked, Bougainvillea was born — a 700-square foot, 3D-printed school in south central Madagascar and Thinking Huts’ first officially completed project.��

According to�� and��, sub-Saharan Africa faces the highest education exclusion rates in the world. In Madagascar, the crisis is acute: three-fourths of secondary-age children don’t attend school due to issues like overcrowding and dangerous commutes. One-third won’t complete primary education, and 97 percent of 10-year-olds who finish primary school cannot read simple sentences.��

Thinking Huts hopes to change that. Bougainvillea is small but mighty, holding up to 30 students and serving as a beacon of hope for the local community and proof of Thinking Huts’ potential to address the global education opportunity gap.��

And while the grunt work of planning and preparing spanned the better part of a decade, the execution was swift — using an industrial-scale 3D printer and a cement mixture, an on-site team printed the modular wall components in just 18 hours. These units were designed to fit together seamlessly, forming a puzzle-like assembly to complete the structure. The roof, doors and windows, handcrafted by local artisans and builders, were added on several weeks later.��

Grout recalls: “When I was looking at the walls being printed, I kept thinking, ‘Oh, my gosh, this is crazy. It’s finally happening.’”��

Patience Pays Off

Thinking Huts was forged at the intersection of two different causes: education and sustainability. For Grout, they are intimately connected.��

“We know that in order for us to continue to increase access to education in these communities, we have to have a focus on sustainable building metrics,” said Kristen Harrington, director of development at Thinking Huts. “A lot of organizations focus on speed. But if you’re looking at how to build more holistic communities and better equip families and address the poverty cycle, you have to take the whole picture into account.”��

While this kind of long-term, intersectional problem-solving does not lend itself to the immediate gratification of a “quick fix” — each decision requires careful thought, planning and foresight — Grout said the result is lasting.����

“It’s not an overnight thing,” said Grout. “We’re trying to set up the next few generations to succeed and go further than us, rather than thinking of the short term. It’s a long haul type of journey.”��

A Relational Approach

For Thinking Huts, this kind of holistic approach means focusing on building strong, equitable, sustainable relationships in their partner communities.��

“Relationship building is a slow drip,” Harrington said. “It’s an opportunity for us to really assess what’s going to be able to create sustainability in these structures for generations.”����

In order to create this sense of longevity, Thinking Huts spends time building trust with community leaders and students, taking their needs and skills into account and assessing how to collaborate with local workers, builders, artisans and technicians. For Bougainvillea, this meant partnering with area manufacturers in the construction process, handing off 3D operational skills that can be applied to future construction projects.

Grout said this relationship-first ethos has roots in her years at 91������, where she said the people she met were the most impactful, including her mentorship with��Mike Leeds (Fin’74).��

“I think even now I’m realizing how critical it is to have a network of people around you,” she said. “The relationships I developed are the biggest things that I took away from school.”

CEO with a Story

Grout said her passion for educational opportunities has been a lifelong journey. Born and abandoned in a rural village in China, she was adopted by American parents at 18 months old and grew up in the U.S.��

“I think I’ve already always been more aware of how people’s lives are different from mine,” said Grout. “I had big visions from a young age, just knowing my life could have followed a very different path. That’s what drew me more to understanding the importance of education.”

The result is a work ethic and leadership style that Harrington said extends beyond her years and has garnered international attention from major media outlets like Forbes and Good Morning America. In fall 2024, Grout was featured as one of��

“Maggie has this true grit and determination,” said Harrington. “She doesn’t want any child to feel like they don’t have the access that she had because she was adopted. So now she can bring opportunity to children in the pockets of the world that often don’t see innovation.”

Honeycomb on the Horizon

For Grout and her team of 10, Bougainvillea is just the beginning. Next up is the Honeycomb Campus. Named for its design of adjoining hexagonal bases, this multi-building project will serve three remote villages on the west coast of Madagascar. The project is set to include solar power and Wi-Fi access and will impact more than 200 students ages four to 16, starting in summer 2025.��

When asked about her approach to the future and how she’d encourage other innovators in philanthropy and sustainability, Grout emphasized a sense of hope.��

“I know that what we do now will have a major impact later on,” she said. “I am trying to aspire for a legacy of change, even if it takes time.”
