A dual-layer glass facade enhances energy efficiency while providing unobstructed views of the surrounding Icelandic landscape in a timber retreat designed for hospitality and relaxation.
5 key facts about this project
01
Forged with a dual-layer glass facade that enhances light entry and insulation.
02
Incorporates geothermal energy systems for sustainable heating and hot water.
03
Features modular guest units with adaptable configurations for diverse visitor needs.
04
Utilizes charred wooden shingles for durability and aesthetic integration with nature.
05
Overlooks the Icelandic landscape, maximizing exposure to natural phenomena such as the northern lights.

### Overview

Located in Iceland, the Northern Mirror project reflects the region’s distinctive landscape and atmospheric conditions, including prolonged sunsets and northern lights. The design focuses on transparency, allowing occupants to engage with Iceland’s natural beauty while creating an immersive internal environment that enhances aesthetic and functional experiences.

### Spatial Organization

The layout strategically divides the building into functional zones. Public areas feature a spacious entrance that promotes relaxation and social interaction, complemented by accessible pathways connecting various sections. Private accommodations are designed as modular units that can host individuals or small groups, offering flexibility in use. Common spaces, including kitchens and dining areas, are designed to facilitate both communal activities and privacy, featuring large windows that enhance connectivity with the external surroundings.

Additionally, the roof is fitted with photovoltaic panels, reinforcing the project's commitment to sustainability by generating energy to support the building's needs.

### Material Selection

The materiality of the Northern Mirror is integral to its design ethos. Externally, double layers of glass enhance energy efficiency and sound insulation, while varying opacity levels cater to specific functional requirements within. Internally, white wood finishes provide warmth and contrast to the modern glass facade. A robust structural framework of steel profiles ensures durability without compromising the minimalist aesthetic. Opaque glass is strategically used to enhance privacy in guest modules, facilitating a balance between openness and seclusion.

This careful selection and integration of materials not only harmonize with the rugged landscape but also promote energy efficiency and environmental responsiveness.

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.
