5 key facts about this project
01
A double-glass roof melts snow into water, directing it to a hydro power system.
02
The building features a water reservoir with a 400 millimeter capacity for efficient runoff management.
03
Cross-Laminated Timber construction provides strength and sustainability while enhancing aesthetics.
04
Integrated green spaces promote plant growth and improve indoor air quality.
05
Easily accessible areas support community interaction, including playgrounds and recycling facilities.

The Iceland Community Center is designed to tackle the challenges of climate change while encouraging community interaction. Located in a snowy region, the center ensures self-sufficiency and energy efficiency, allowing people to feel comfortable even in harsh weather. The design concept focuses on managing resources, particularly using snow as a key element in the building's function.

Design Features

A significant aspect of the center is its double-glass roof, which has a heating wire system embedded within. This system melts the snow that accumulates, turning it into water that flows into the building's hydro power system, centrally located within the structure. The roof is designed at a 45-degree angle to help the snow slide off easily, minimizing the risk of buildup and ensuring consistent performance.

Water Management

The community center includes a water reservoir with a capacity of 400 millimeters. This reservoir captures both rainwater and melted snow, providing a steady supply of water for various needs. The clean water is filtered through the hydro power system and repurposed for indoor irrigation, supporting the building's function as a greenhouse while enhancing air quality inside.

Structural Composition

Construction relies on Cross-Laminated Timber (CLT) and Glued Laminated Timber (Glulam) for strength and stability. These materials support the structure and reflect a commitment to sustainable building practices. The community center also contains spaces for different activities, including a public greenhouse, recycling area, and children’s playground, all designed to foster a sense of belonging among residents.

Interior Environment

The layout promotes social interaction, incorporating areas like a shower room, kitchen, dining room, and conference room. Natural light and ventilation are prioritized throughout the design, creating an open and welcoming space that encourages gatherings. Green spaces integrated within the interior contribute to a pleasant atmosphere, blending nature with daily life in functional ways that enrich the overall experience of the community.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
