Translucent Concrete and Volcanic Rock Harmonizing in a Geothermally Efficient Visitor Hub

Project in-detail

Crafted from local volcanic rock and enhanced with translucent concrete, the coffee shop seamlessly integrates into Iceland's rugged terrain while harnessing geothermal energy to create a welcoming space for visitors to relax and learn about the unique landscape.
5 key facts about this project
01
Constructed from local Pelelith, the design emphasizes energy efficiency through natural insulation.
02
Translucent concrete elements enhance natural light while maintaining thermal performance.
03
A hexagonal layout fosters community interaction and encourages diverse visitor flow.
04
The integration of geothermal heating systems reflects the site's geological features.
05
Biophilic design principles are used to create habitats for local biodiversity within the landscape.
The project known as "Straw" features an architectural design for a coffee shop situated within Iceland's volcanic landscape, capturing the essence of the surroundings while serving a functional purpose. This architectural endeavor represents a thoughtful integration of modern design principles with the unique geographical and environmental characteristics of the area, making it a significant addition to the local context.

The primary function of the "Straw" coffee shop is to provide a space where visitors can enjoy coffee and learn about the volcanic landscape and geothermal systems that characterize Iceland. The architectural form promotes not only a comfortable atmosphere for patrons but also facilitates educational opportunities, making it a point of interest that blends leisure with knowledge-sharing.

Central to the project are the carefully considered layout and design elements which enhance its functionality and connection to the environment. The structure employs a hexagonal configuration, optimizing space for both public and private functions while facilitating natural movement throughout the areas. This layout includes prominent spaces such as the coffee shop, a visitor information center, an exhibition area dedicated to volcanic activity, office spaces, and restrooms, all interconnected by thoughtfully designed circulation pathways.

Materiality plays a crucial role in this project, with an emphasis on local and sustainable choices that reflect the geological context of Iceland. The primary material used is Pelelith, a type of local volcanic rock that serves to insulate and regulate building temperatures effectively. Reinforced concrete and translucent concrete are utilized not only for their structural properties but also for their ability to manage light and thermal exposure within the building. The innovative use of translucent concrete allows ambient light to filter in, creating a welcoming and pleasant ambiance while maintaining energy efficiency.

To enhance the project’s sustainability, it incorporates advanced energy systems designed to leverage Iceland's geothermal resources. Geothermal heating is used to regulate the indoor climate, while natural ventilation methods are employed to ensure a fresh and comfortable atmosphere. The integration of expandable pathways and open areas promotes natural airflow, reducing the need for mechanical cooling systems. The architectural design focuses on biophilic principles, reinforcing a connection to nature through landscaped courtyards and spaces that encourage the presence of biodiversity.

One of the unique design approaches of "Straw" lies in its adaptability to various functions and events. This flexibility is essential in a public space where varying visitor needs must be accommodated. The modularity of the layout enables the coffee shop to serve as a venue for community gatherings, exhibitions, and educational programs, making it a versatile asset to the locality.

In addition to its functional attributes, the architectural design of "Straw" pays homage to the rich cultural heritage of Iceland. It reflects an understanding and appreciation of the local environment and engages with it rather than imposing on it. This nuanced approach invites potential visitors to immerse themselves not only in the experience of enjoying coffee but also in the broader narrative of the volcanic landscape that surrounds them.

The project exemplifies a seamless blend of architectural design and environmental awareness, with integrated systems ensuring energy efficiency and comfort. By exploring the architectural plans, sections, and detailed designs, readers can gain deeper insights into how "Straw" fulfills its role as a coffee shop while celebrating Iceland's unique geothermal features and cultural identity. Engaging with the project presentation will provide a comprehensive understanding of the architectural ideas that informed its design, enhancing appreciation for this thoughtful blend of functionality and environment.

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.
