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.

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.
