Set against the rugged landscape of Iceland, the design seeks to create a meaningful relationship between the natural environment and human-made structures. Its setting is marked by diverse geological features, which serve as both inspiration and foundation for the spaces being proposed. Central to the plan is a grotto, designed to evoke the feeling of exploring hidden depths. This project invites visitors to engage with the striking features of the land while providing a place for reflection and exploration.

Grotto Design

The grotto is the heart of the design, capturing the essence of the landscape's natural fissures. Its interior consists of gentle curves that create intimate spaces, offering a sense of shelter from the elements. This design allows visitors to connect with the surroundings on a personal level, encouraging exploration and discovery as they navigate through the space.

Pathways and Movement

Pathways weave throughout the site, created with a flexible design that changes in width and purpose. These routes guide visitors toward key locations, including the caves of Grjótagjá and an open-air museum. With various observation points along the way, the pathways enhance the experience, allowing visitors to pause and appreciate the beauty of the landscape, highlighting the connection between architecture and nature.

Pinnacle Tower

A prominent pinnacle tower rises above the site, providing expansive views of the surrounding area. Its vertical design contrasts with the grotto and serves as a navigation marker. Various viewing platforms are incorporated into the tower, encouraging visitors to appreciate different perspectives of the landscape, thus deepening their engagement with the environment.

Material Expression

The selection of materials reinforces the connection to the site. The grotto's façade is clad in basalt plates, similar to the natural formations found in Iceland, making the structure visually align with its surroundings. Inside, timber facings on the ceiling add warmth to the space, creating a welcoming atmosphere. The roof, covered in turf, is a nod to traditional Icelandic architecture and also provides natural insulation, adding an ecological aspect to the overall design.

Amidst these elements is a café located within the grotto, designed for visitors to gather and rest. It offers a comfortable place to enjoy the views and the atmosphere, allowing for moments of pause as guests experience the unique blend of architecture and the natural beauty of Iceland.

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.
