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 MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.
