"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.

Vancouver Tall Challenge: Building Higher Downtown

`
Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
