Spherical Accommodations Crafted from Basalt and Timber Integrating Geothermal Features

Project in-detail

Crafted from local basalt and timber, the design employs spherical forms to harmonize with the Icelandic landscape while incorporating geothermal features, providing flexible lodging options for visitors.
5 key facts about this project
01
Spherical units allow for reconfigurable living arrangements.
02
Local basalt stone facade integrates with the surrounding terrain.
03
Geothermal features provide sustainable heating and relaxation areas.
04
Phase change materials enhance thermal efficiency in guest accommodations.
05
The design draws inspiration from Norse mythology, particularly Yggdrasill.
Mímisbrunnur is an architectural project located near Lake Mývatn in Iceland that seeks to harmonize the design with the region's unique geological features. The project consists of flexible accommodation units, known as spherical structures, as well as permanent buildings. It signifies a thoughtful integration of modern living spaces with the natural landscape, emphasizing sustainability and energy efficiency.

The primary function of Mímisbrunnur is to provide lodging and communal spaces for guests. It effectively accommodates a variety of uses ranging from tourism to social gatherings, promoting interaction with the dramatic Icelandic scenery. The design features movable spherical units, referred to as "balls," which enhance flexibility and adaptability. These units offer living spaces with panoramic views and an innovative approach to user experience.

Sustainability is a core aspect of this project. The design utilizes locally sourced basalt stone for façade cladding, which allows the architecture to blend seamlessly with the surrounding terrain. The spherical units incorporate phase change materials (PCM) to improve energy efficiency and thermal comfort. Large areas of glazing are employed to maximize natural light, reducing reliance on artificial lighting while providing occupants with views of the natural landscape.

The unique approach of Mímisbrunnur lies in its multifunctional and dynamic design. The use of movable spheres allows for reconfigurable living arrangements, enabling users to experience the natural environment from varying perspectives. Furthermore, the integration of hot spring areas takes advantage of the geothermal activity characteristic of the region, offering a distinctive setting for relaxation and rejuvenation.

In addition to the spherical units, the permanent buildings—namely The Rock and The Hills—serve as communal spaces. The Rock is intentionally designed to resemble its rocky surroundings, while The Hills are designed with amphitheater-style spaces, promoting community engagement. Both structures foster a sense of togetherness among residents and visitors.

Architectural plans and sections illustrate the thoughtful spatial organization and functionality embedded in the design. The project employs efficient water management techniques and is designed to minimize environmental impact. The comprehensive approach to sustainability and local material use underscores Mímisbrunnur as a model for future architectural endeavors.

For a more in-depth understanding of the project, including the architectural designs and ideas behind the structure, it is recommended to explore the project presentation further. Detailed architectural plans and sections provide valuable insights into the design processes and considerations that shape Mímisbrunnur.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
