The Myvatn Community Centre is located in Iceland and aims to meet the needs of the local community through a focus on sustainability. Serving as a gathering place for residents, the building incorporates features that promote environmental care and community engagement. The design follows the principles of cradle to cradle, emphasizing ways to reduce, reuse, remake, recover, and renew materials. This approach enhances both the building's function and the sense of community.

Site Planning and Layout

The layout of Myvatn Community Centre is organized for ease of access and functionality. It features a main entrance that leads into a welcoming reception area, where visitors can quickly orient themselves. The design includes various spaces tailored to community activities, such as places for meetings, learning, and socializing. This intentional arrangement encourages participation and connection among residents.

Sustainable Features

A key aspect of the centre is the greenhouse that uses geothermal energy for heating. This makes it possible to grow fresh produce, even in Iceland's cold climate. The greenhouse not only supports local agriculture but also serves as a learning tool for community members. A multi-functional room is incorporated into the design, allowing for a range of activities that stimulate social interaction and collaboration.

Material Selection

The choice of materials plays a significant role in ensuring the building's sustainability. Ethylene Tetrafluoroethylene (ETFE) is chosen for its lightweight nature and complete recyclability. Glued Laminated Timber (glulam) comes from FSC-certified sources, reinforcing responsible forestry practices. Concrete with volcanic ash is used for its durability and local relevance, supporting both the structure and environmental goals.

Innovative Systems

The Myvatn Community Centre employs advanced systems to enhance efficiency. A high-performance HVAC system improves energy use throughout the facility, while a greywater recycling system manages water resources effectively. Insulation made from Icelandic sheep wool also contributes to energy efficiency and supports local industry. Together, these elements create a practical and enduring resource for the community.

The entrance features a large glass façade that allows ample natural light to flow in, creating a bright atmosphere that connects the interior spaces with the beautiful landscape outside.

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.
