5 key facts about this project
01
ETFE panels allow for significant natural light while reducing heat loss.
02
Coupled roof frames create open, column-free interior spaces.
03
The terraced promenade fosters social interaction and community engagement.
04
Hydroponic farming facilities promote sustainable practices within the community.
05
Rainwater collection systems are integrated into the pitched roof design.

Triple Peaks is located in Skútustaðahreppur and focuses on the ideas of community and recycling. The design serves both existing residents and new community members, creating a center that encourages social interaction while promoting environmentally friendly practices. The project aims to turn standard recycling into something more meaningful, featuring three main activities: managing organic waste, exchanging second-hand goods, and engaging in collaborative upcycling.

Spatial Configuration

The design includes three main spaces: a greenhouse, a second-hand resource exchange center, and a workshop. Each area is designed to fulfill its specific purpose while allowing for fluid movement and interaction. The second-hand resource exchange center sits at the heart of the building, connecting the other two spaces for easy access and engagement.

Promenade Design

Within the second-hand resource exchange center, the terraced promenade extends diagonally through the space. It serves as an informal area for displaying and interacting with second-hand items, similar to a marketplace. This design encourages community gatherings and fosters connections among users. At the northern end, the workshop is dedicated to various upcycling activities, reinforcing the project's focus on creativity and resource use.

Architectural Form

The overall shape of Triple Peaks draws inspiration from traditional Icelandic architecture. By using pitched roofs, the design creates three distinct volumes that represent the separate programs. This method enhances visual appeal and clarifies the connection between each space and its function. The interplay of space and volume highlights the building’s purpose as a community hub, where people come together to interact and collaborate.

Structural Details

Each of the four volumes features coupled roof frames supported by wooden columns. This approach reduces the need for numerous structural supports, resulting in open interior spaces that promote social interaction. The exterior is well-insulated to withstand the local climate. Large skylights are placed throughout the building to bring in natural light while minimizing energy loss. The sloped roofs also allow for rainwater collection, showcasing the commitment to sustainability woven into the design.

Through these thoughtful details, the project creates an environment that fosters community engagement. The combination of distinct volumes and the clever use of light results in a space that invites activity and connection.

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.
