The Light Triangle is located near Lake Myvatn in Reykjahlio, Iceland. It features a triangular design that focuses on enhancing user experience through effective use of space and natural light. Flexible areas within the building allow for various activities, accommodating the needs of different users in a tranquil setting.

Architecture Concept

At the heart of the design is a large skylight that plays a key role in maximizing light. Situated centrally and elevated, the skylight allows sunlight to flow into the space. Light reflects off the pavement, illuminating surrounding areas and creating a connection between inside and outside.



Environmental Responsiveness

The architecture responds well to its environment, featuring a triangular base defined by a steel envelope that forms the exterior. This layer provides strength and durability. Inside, a wooden envelope brings warmth and a natural quality to the interior spaces. This thoughtful combination enhances both functionality and aesthetics.



Material Choices

The skylight consists of triple-glazed hermetic units with PVC profiles, which improve insulation and energy efficiency. An inclined sheet metal roof is effective in directing water away while contributing a sleek profile. The facade uses glass and prefabricated concrete slabs covered with Corten steel, which withstand the local climate and requires little maintenance.



Functional Layout

The layout includes key functional areas such as waiting spaces, an office, a coffee shop, and storage. An inner courtyard serves as a communal area, enhancing interaction among users. These spaces are designed to encourage a sense of community and connection, enhancing the overall experience within the building.



The skylight not only acts as an important design feature but also optimizes energy performance, creating a greenhouse effect that helps maintain comfort and harnesses solar energy throughout the day.

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.
