Constructed from a unique mix of black sand and concrete, enhancing aesthetic and structural integrity.
02
Utilizes geothermal energy for heating and hot water, promoting energy efficiency.
03
Designed as a monolith to blend seamlessly with the surrounding Icelandic landscape.
04
Incorporates cave-like openings for natural light and expansive views, enhancing user experience.
05
Fosters sensory engagement through varied spatial configurations and diverse pathways.
The architectural project under analysis is an innovative structure that incorporates the themes of monolith and cave, designed to harmonize with its natural Icelandic surroundings. The design emphasizes a connection between the built environment and its landscape, utilizing local materials to create a cohesive narrative that reflects the geographic and cultural context of the area. The architectural approach serves as a functional space while contributing to the ongoing dialogue of sustainability and ecological awareness.

Design Concept and Functionality

The project represents a synthesis of natural forms and human needs, with a monolithic structure that offers both stability and aesthetic appeal. It functions as an observatory and retreat, providing visitors with an immersive experience. The design encourages exploration, transitioning through various spatial configurations that mimic the protective qualities of a cave while offering diverse perspectives of the natural landscape.

The primary elements of the structure include the vertical monolith that rises prominently against the skyline, punctuated by cave-like openings. These openings allow natural light to penetrate interior spaces while providing sightlines to the surrounding environment. The use of local concrete, with black sand integrated into the mix, ensures that the structure not only complements the geological characteristics of Iceland but also reduces its carbon footprint.

Unique Design Approaches

What sets this project apart from conventional architectural designs is its deep integration with the landscape. The architecture does not simply sit on the land; it engages with the topography, contouring to align with natural features. The careful crafting of interior spaces, which emulate cave-like experiences, provides users with a sense of enclosure while promoting a connection to the exterior. This duality fosters an environment that is both intimate and expansive.

In terms of materiality, the commitment to local resources is noteworthy. The project utilizes a mix of concrete and black sand, which contributes to a unique texture and color palette that echoes the natural landscape. Additionally, the design incorporates geothermal heating strategies, drawing on Iceland's abundant thermal energy resources. This approach enhances the building's energy efficiency while keeping the environmental footprint minimal.

Sensory Experiences and Structural Details

The project invites visitors to engage with its spaces through a series of carefully designed pathways. As users move from exterior to interior, they encounter varied experiences that highlight contrasts between openness and enclosure. Each level offers different vantage points, giving users an opportunity to appreciate the expansive views of the surrounding terrain.

Architectural elements include large, strategically placed openings that frame natural vistas and allow the interplay of light and shadow throughout the day. This dynamic relationship with the external environment is central to the project, encouraging visitors to engage with the landscape in a meaningful way.

The overall design embodies principles of sustainability, user engagement, and contextual integration, setting a standard for future architectural projects in similar environments. The careful consideration of material choices, spatial organization, and environmental strategies fosters a meaningful interaction between architecture and nature.

For further insights into this unique project, including detailed architectural plans, sections, and design elements, readers are encouraged to explore the comprehensive presentation of the project. Delve into the architectural ideas that shaped this innovative design and their implications for future construction in harmony with the natural world.

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.
