The Andes House Reimagined — Aluminum Leads Modular Innovation
On the Andes House prototype, and what shifts when the materials logic moves to aluminum.

In 2022, Ignacio Rojas Hirigoyen Architects teamed up with The Andes House design group to unveil a game-changer in Casablanca, Chile: an Industrialized Building System Prototype—a modular marvel tackling the global housing crisis. Originally dubbed "The Andes House," this 85-square-meter prototype was a bold step toward affordable, sustainable construction, using recycled wood fiber panels and lightweight steel. But what if we shifted the materials logic to aluminum—a low-carbon, endlessly recyclable powerhouse? Let’s reimagine The Andes House with aluminum at its core, amplifying its mission for a world that desperately needs smart, scalable housing.
Adaptable Structures has been doing research and development on industrial methods since 2014. The Original Andes House: A Modular Milestone Picture this: a sleek, gabled structure perched on tripod foundations in Chile’s rugged terrain, assembled in hours by a small crew. The Andes House prototype wasn’t just a house—it was a system. With interlocking wooden sub-modules framed by steel, it offered Lego-like flexibility: snap together a home, a school, or a clinic, then take it apart and rebuild it elsewhere. Its sustainability cred came from recycled wood, a fog-catching roof for water, and solar panels for off-grid living. At its heart was a vision—fast, practical housing for a crisis-hit world.
But while wood and steel worked, they carried limits: timber’s processing waste (up to 40% lost) and steel’s heft clashed with the dream of ultimate efficiency. Enter aluminum—a material that could turbocharge this concept into Construction 5.0 territory.
Why Aluminum? Aluminum isn’t just a shiny upgrade; it’s a materials revolution. Imagine The Andes House reengineered with low-carbon aluminum modules:
- Lightweight Strength: Aluminum cuts the weight of steel without sacrificing durability, making transport and assembly a breeze—crucial for remote or disaster-struck areas like Chile’s coast.
- Zero Waste: Unlike wood, which loses efficiency in milling, aluminum can be remelted with 95% less energy than primary production. Pair it with a waste-free manufacturing process, and you’re looking at a system that leaves nothing for landfills.
- Recyclability: At the end of its life, an aluminum Andes House doesn’t rot or rust—it’s recovered and reused, feeding a circular economy that wood and steel can’t match.
- Decontamination Edge: Aluminum’s corrosion resistance means you can power-wash interiors clean—a low-liability perk for housing in tough conditions.
Aluminum-Powered Modularity
The original Andes House thrived on simplicity: standardized parts locked with wedges, no heavy machinery needed. Swap in aluminum, and that simplicity scales up. Picture lightweight aluminum sub-modules—46 core parts—forming the same 85-square-meter footprint. Two bedrooms, two bathrooms, and an open living space, all snapped together with precision. The tripod foundations stay, but now they’re supporting a structure that’s easier to lift, shift, or stack.
Anyplace Modular Research and Development
Need more space? Add a module. Want to repurpose it as a clinic? Swap interiors—all removable for quick reconfiguration or cleaning. Aluminum’s versatility turns The Andes House into a chameleon: a home today, a community hub tomorrow, without the waste of tearing down and rebuilding.
Sustainability Supercharged
The Andes House already leaned green with its recycled wood and passive features. Aluminum takes it further:
- Carbon Cut: By dodging timber’s processing losses and steel’s energy-intensive production, aluminum—especially low-carbon variants—slashes the carbon footprint. Think hydroelectric-powered remelting, leaving only oxygen as a byproduct (shoutout to tech like Elysis ( www.elysis.com)). More on the sustainability of aluminum www.aluminum.org
- Forest Relief: Moving away from wood eases pressure on Chile’s forests, letting them sequester carbon naturally while we build smarter.
- Longevity: Aluminum resists rot, pests, and wear, outlasting wood in harsh climates and reducing replacement costs.
That fog-catching roof? Still there, now atop an aluminum frame that’s lighter to install and tougher against the elements. Solar panels? They fit seamlessly, powering an off-grid life with even less structural strain.
Construction 5.0 DfIND: Aluminum’s Moment
The Andes House tapped into Industry 4.0—automation, efficiency, and scalability. Aluminum pushes it to Construction 5.0: an industrialized building that’s not just fast but future-proof. Originally, Ignacio Rojas Hirigoyen and The Andes House aimed to solve housing shortages worsened by pandemics, price spikes, and climate chaos. An aluminum shift doubles down on that mission:
- Speed: Modules roll out of factories anywhere, containerized for rapid deployment—think shelters in hours for Chile’s earthquake zones.
- Scale: A system designed for mass production could churn out thousands of units, meeting Latin America’s housing deficit head-on.
- Resilience: Aluminum’s durability stands up to the region’s wild weather, from coastal fog to inland heat.
A Vision Reborn
The Andes House was always about accessibility—architecture that serves, not distances. Reimagined with aluminum, it’s leaner, greener, and meaner (in a good way). It’s still —cozy, practical, adaptable—but now it’s a lightweight titan ready to tackle housing crises worldwide. Less waste, more possibility, all while letting forests breathe. This isn’t just a tweak; it’s a transformation. Aluminum turns The Andes House into a beacon of what construction could be—sustainable, scalable, and relentlessly practical. Ignacio Rojas Hirigoyen’s vision meets a materials logic that’s ready for the future. Who’s in for the ride?
