The Iceland Cave Tower project is an architectural endeavor that seamlessly integrates with the rugged Icelandic landscape. Its design reflects an exploratory approach to merging natural and constructed environments, drawing inspiration from geological formations inherent to the region. The project embodies a concept where architecture serves not only as a physical structure but also as a narrative space that invites interaction and contemplation.

This project focuses on creating a multi-functional tower designed to engage visitors with its environment. The primary function is to serve as an observation point, providing breathtaking views of the surrounding geological features and landscape while also offering sheltered spaces for relaxation and reflection. Thus, the architecture is intended to foster a connection between users and nature, enhancing the experience of the unique Icelandic conditions.

In conceptualizing the design, the architects have prioritized the use of local materials. Basalt stone is employed prominently in the construction, reflecting the geological character of Iceland and contributing to the thermal efficiency of the structure. The inclusion of timber introduces warmth to the interiors, contrasting effectively with the stone façade. Glass elements create transparency, allowing natural light to flood the interiors while framing views of the exterior environment.

One of the notable aspects of the Iceland Cave Tower is its distinctive form, which mimics the rugged, angular profiles of natural cave formations. This variable geometry serves not only aesthetic purposes but also functional ones, promoting airflow and enhancing natural lighting conditions. The architectural design deliberately avoids conventional shapes, opting instead for a more organic, carved appearance that aligns with the topography of the site.

The architectural layout includes both public and semi-public spaces that facilitate different modes of interaction. By creating a sequence of experiences through varying spatial configurations, the design encourages exploration and movement. The multi-level layout allows visitors to ascend and descend through the tower, experiencing shifts in perspective and interaction with light and shadow.

The project emphasizes sustainability, using locally sourced materials and passive heating techniques. The structural choices made in the design aim to minimize energy consumption and environmental impact while enhancing the resilience of the building against Iceland’s climatic challenges.

In summary, the Iceland Cave Tower exemplifies innovative architectural thinking grounded in local context. Its design integrates functional needs with environmental considerations, establishing a harmonious relationship with the surrounding landscape. For further details, including architectural plans, sections, and designs, we encourage readers to explore the project presentation. Engaging with these elements will provide deeper insights into the architectural ideas that define this unique Icelandic project.

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.
