Translucent Concrete and Volcanic Aggregate Shape a Geothermal Coffee Shop in Iceland

Project in-detail

Constructed using translucent concrete and volcanic aggregate, the coffee shop harnesses geothermal energy to integrate seamlessly with Iceland's landscape while promoting community interaction.
5 key facts about this project
01
Constructed with translucent concrete, the building allows natural light to permeate while retaining privacy.
02
Utilizes volcanic aggregate as a primary material, enhancing thermal insulation and energy efficiency.
03
Incorporates a modular hexagonal design that facilitates flexible space usage and promotes community interaction.
04
Employs geothermal energy systems for sustainable heating and cooling, minimizing ecological impact.
05
Features a landscape that supports local biodiversity, blending the built environment with nature.
The architectural project "Straw" is designed as a coffee shop located in Iceland, drawing inspiration from the region’s unique geological characteristics, including volcanic rock and geothermal energy. This design is characterized by a modular structure that utilizes hexagonal forms, promoting both functionality and aesthetic appeal. The primary objective of "Straw" is to create a space that fosters community interaction while remaining environmentally sustainable.

The coffee shop encompasses a combination of public and private areas that accommodate various activities, such as social gatherings and everyday operations. The design integrates natural light through strategically placed skylights and uses energy-efficient practices rooted in the Icelandic landscape. The choice of materials reflects both local availability and the demand for sustainable performance, ensuring compatibility with the surrounding environment.

Material and Structural Innovation

One of the standout features of "Straw" is its material composition, which includes concrete, peleth, translucent concrete, polycarbonate, and perlite. Each material serves a specific purpose while contributing to the overall sustainability of the project. The use of volcanic aggregate not only aids in reducing the carbon footprint but also enhances thermal insulation and structural resilience. This focus on local materials underscores the project’s commitment to sustainability and ecological sensitivity.

The design incorporates advanced geothermal systems that optimize indoor climate control by utilizing the earth's natural heat. This represents a unique approach in architectural design, utilizing passive heating and cooling mechanisms to minimize energy consumption. Additionally, the building’s hexagonal modules encourage efficient space utilization and facilitate natural ventilation, which enhances occupant comfort.

Community-Centric Design Approach

"Straw" emphasizes community engagement through its layout and space planning. The interconnected public areas are designed to encourage interaction among visitors, fostering a sense of belonging and community spirit. This is further reinforced through transitional spaces that serve not just as physical connectors but as social hubs. This unique approach sets "Straw" apart from typical coffee shop designs, focusing not merely on the commercial aspect but also on social sustainability.

Moreover, the careful integration of the architecture with the surrounding landscape allows for a seamless flow between the built environment and nature. Landscaping elements are designed to support local biodiversity while enhancing the overall aesthetic of the project.

For a comprehensive understanding of the architectural strategies employed in "Straw," it is recommended to explore the architectural plans, architectural sections, architectural designs, and architectural ideas presented. Delving into these elements will provide deeper insights into the project's innovative approaches and its contributions to sustainable architecture in unique geographical contexts.

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.
