Emilio López Arquitecto Builds a 50 m² Volcanic Hillside Retreat from Salvaged Materials in Ecuador

Fifty square meters is not much house. On the eastern flanks of Ilaló, an extinct volcano fifteen kilometers from Quito, that constraint becomes the entire argument. Quinchuyaku House, designed by Emilio López Arquitecto, is a compact timber cabin at 2,600 meters altitude that draws half its material from the demolition of an old house in central Quito: beams, columns, windows, doors, stairs, countertops. It runs on solar power, drinks only rainwater, and composts its own waste. The building is a closed loop disguised as a weekend retreat.

What makes the project worth studying is not the checklist of sustainable features, though the checklist is long. It is the way López treats scarcity and salvage as formal generators rather than limitations. The house's double-opening envelope, two funnels converging along an east-west axis, is oriented to pull cross ventilation through the interior and frame the surrounding eucalyptus forest that the project itself aims to gradually replace with native species. The roof planes detach from the facade plumb lines to accommodate water harvesting. Every quirk in the geometry traces back to a resource problem solved without mechanical systems. The result is a cabin that looks simple and operates with the metabolic complexity of the hillside it sits on.

Salvaged Timber as Structure and Character

From the outside, Quinchuyaku reads as two white angled walls cinching a gridded timber facade. The post-and-beam frame, assembled entirely from recycled lumber, is left exposed on the principal elevation, giving the house a warm, modular face that contrasts with the smooth rendered panels flanking it. The grid is not decorative: each opening holds a salvaged window or door, sized by what was available rather than what was drawn. López turned the dimensional inconsistencies of reclaimed material into a composition that feels handmade without being precious.

The white cladding folds at sharp angles to direct rainwater off the envelope and into storage tanks set nearby. Because the roof does not align with the walls below, the building gains an unexpected sectional profile, part tent, part funnel. Seen from the hillside path, the cabin looks simultaneously rooted among the eucalyptus trunks and slightly airborne, as if the landscape could reclaim the ground beneath it at any time.

Living in 50 Square Meters

Inside, the economy of space is rigorous. The living area doubles as a reading room, with timber floors and walls creating a continuous warm surface that absorbs afternoon sunlight pouring through the glazed east-west openings. There are no partition walls in the conventional sense; furniture and changes in ceiling height do the work of separating zones. A person reading near the glass doors occupies the same volume as the kitchen behind them, yet each area feels distinct.

The kitchen tucks under exposed beams with open shelving and a horizontal window that frames a close view of the forest canopy. Countertops and the staircase were built from reclaimed components, and the detailing is rough in the best way: joinery that acknowledges the history of the wood rather than sanding it into anonymity. The result is a domestic interior that carries the patina of two buildings, the old Quito house and the new volcanic one, simultaneously.

Framing the Landscape Through Work and Rest

A desk placed against the gridded window wall turns the sloped terrain and scattered trees into a working backdrop. The timber mullions break the view into dozens of small frames, so the landscape registers as texture rather than panorama. It is a deliberate move: you are not meant to gaze passively at the volcano but to live inside its ecology, aware of wind, light, and the slow replacement of eucalyptus with native planting happening just beyond the glass.

Cross ventilation driven by the east-west funnel orientation eliminates any need for air conditioning in Ilaló's dry temperate climate. The house breathes with the hillside. Gray water from bathrooms and the kitchen is redirected to irrigate newly planted trees, while terraced gardens and infiltration ditches outside manage stormwater and rebuild eroded soil. Living here means participating in a landscape restoration project whether you intend to or not.

Mingas and the Politics of Building Together

López built Quinchuyaku through mingas, the Andean tradition of participatory communal labor. Local workers and close friends made design decisions on site during construction, and the built result diverges from the initial drawings in ways that López treats as improvements rather than compromises. Columns land where collective judgment placed them. Window groupings shifted to accommodate available salvaged frames. The architecture carries the intelligence of many hands.

In a discipline obsessed with authorial control, this is a provocation. The minga process means the architect proposes a framework and then cedes portions of it to collaborative problem-solving. The building's slight imperfections, a beam that is thicker than its neighbor, a door that sits a few centimeters off-center, are evidence of that negotiation. They also make Quinchuyaku more legible as a building that was made rather than merely manufactured.

Plans and Drawings

The site plan reveals how tightly the cabin is threaded between existing trees on the contoured slope. The footprint is minimal, barely a notch in the hillside, with the dual funnel orientation clearly legible in the roof outline. Surrounding tree canopies dwarf the structure, reinforcing the project's ethos: the house is a guest on this land, not a colonizer of it. Terracing lines and infiltration ditches are suggested in the grading, hinting at the soil regeneration strategy that extends the project well beyond its walls.

Why This Project Matters

Quinchuyaku House is an argument against the idea that sustainability requires expensive technology or large budgets. Solar panels, rainwater harvesting, dry toilets, gray water irrigation, and composting are all straightforward systems here, made feasible by the small scale of the building and the willingness to work with imperfect salvaged materials. The real innovation is organizational: the minga process, the acceptance of on-site improvisation, and the commitment to replacing an invasive forest with native species over years, not months. The house is designed to improve its site slowly, which is a time horizon most architecture refuses to engage with.

For architects working in the Global South or anywhere that resources are constrained, this project offers a useful model. It demonstrates that a 50 m² cabin built from 50% recycled material by a community of non-specialists can be spatially generous, ecologically restorative, and architecturally precise. López proves that circularity and craft are not opposing values. They are, in fact, the same discipline practiced at different scales.
