Fjallahellir Mountain Cave is an architectural endeavor that blends a modern cinematic experience with the natural beauty of Iceland. Set against the striking landscape, the building is designed to reflect the character of its environment while serving as a space for Icelandic cinema. The project emphasizes clear lines and modest forms, creating a strong connection to the nearby geographical features.

Architectural Layout

The building consists of three main sections: Viewing, Meeting, and support spaces. This organization provides clarity and accessibility for visitors, enhancing their overall experience. The entry is oriented towards Grjótagjá, guiding individuals into the building and inviting them to participate in the cinematic experiences offered.



Transitional Experience

Visitors enter through a long ramped corridor. This corridor serves as a buffer, allowing guests to leave the outside world behind and adjust to their new surroundings. Besides functioning as the main entrance, it includes support areas such as coat check, contributing to a smooth arrival and setting the stage for the experience ahead.



Communal Atrium

At the center of Fjallahellir is a sunken atrium that provides connections to the landscape and the overhead sky. Designed to encourage interaction, this space features a bar for refreshments and a large pre-function area that promotes social engagement. High ceilings and open views to the outside create a lively atmosphere, merging the interior with the environment.



Film Experience and Design Detail

The path to the theater evokes a sense of entering a cave, with the space intentionally placed below ground to take advantage of the earth’s natural warmth. Above the theater, a gallery showcases heavy timber structures that reflect local craftsmanship. A dramatic catwalk invites visitors to explore, linking different parts of the building. The striking wooden wall draws the eye and encourages guests to discover what lies beyond, leaving a lasting impression of the space and its connection to the landscape.

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.
