Design Solution: The design began with a meticulous botanical study of the wooded site. To ensure that no trees were felled, the architectural volumes were broken into separate modules that weave organically through the natural clearings and topographical contours. Glass corridors connect these volumes while also connecting the inhabitants with the exterior.

This nonorthogonal footprint minimizes environmental impact and creates inward-facing courtyards, which promote consistent cross-ventilation and soft daylighting passing through the trees. The thermal strategies implemented eliminate the need for HVAC systems, relying on passive interior airflows and convection as well as a careful balance of thermal mass and insulation. The project achieves complete energy autonomy via integrated rooftop photovoltaics and comprehensive wastewater treatment. A system of infiltration trenches, mineral filters, and constructed wetlands naturally purifies all gray and black water, which is later used to irrigate the landscape. Rainwater is harvested via a simple system that collects runoff from the roof into ceramic terra-cotta vases—fabricated by local artisans—distributed around the exterior of the house.

Critically, the dwelling serves as an economic model. While typical construction in Ecuador allocates approximately 30 percent of the budget to labor, this project channeled 70 percent directly to skilled workers. This investment empowered local Quechua builders, whose ancestral artisanal expertise in earth building techniques was central. By prioritizing local craft and expertise, use of raw unprocessed materials, the dwelling expresses a harmony between high-performance design, ecological stewardship, and community vitality.

Structure and Materials: The structure uses laminated pine grown near the Cotopaxi volcano, benefiting from mineral-rich volcanic ash. Walls are bahareque, interwoven reeds plastered with earth sourced from the site, finished in quartz, earth and lime. These incorporate natural plant-based gums, ensuring non-cracking durability. The thermal envelope is sealed by a ventilated facade of burnt local pine. The roof features a 4-inch-thick layer of carrizo, earth, lime, and lightweight volcanic pumice rock. A roof layer of burnt-wood siding is over an air cavity. Interiors have bamboo flooring and polished concrete. Local artisans crafted the wood window frames, doors, and tadelakt—a lime-plaster finishes—in the showers.
