"LUCIÉRNAGA" is located in the Vale de Moses and is designed to blend into the mountainous landscape while providing a peaceful space for rest. The concept is inspired by bioluminescent insects, resulting in small pods that emit gentle light. This design aims to create a connection between the built environment and nature, enhancing comfort and self-sufficiency for users.

Design Concept

The layout consists of two main areas: a rest area and a cleanness area. The rest area focuses on a central bed, creating a calming space for relaxation. In contrast, the cleanness area is divided to maintain privacy, allowing for necessary functions without compromising comfort. This thoughtful arrangement encourages interaction with the natural surroundings.

Materiality

The design features a rock basement, with wood used for the floor, divisions, and roof, alongside rammed earth for the walls. These materials not only support sustainability but also connect the structure to its environment. Using locally sourced materials helps reduce the ecological footprint and enhances the building's longevity.

Sustainability Features

"LUCIÉRNAGA" incorporates systems for self-sufficiency, such as photovoltaic panels and atmospheric water capture. These elements promote environmental responsibility by reducing dependence on external resources. The positioning of the pods follows the natural contours of the land, which aids in proper drainage and protects the integrity of the landscape.

Design Detail

Large openings in each pod offer sweeping views of the surroundings, bringing ample natural light into the spaces. This design choice invites the outdoors in, enriching the experience of both the architecture and the landscape. The fluid transition between inside and outside enhances the sense of tranquility for occupants.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
