Translucent ETFE Dome Over Sustainable Vertical Gardens in Desert Habitat

Project in-detail

A transparent ETFE dome integrates passive ventilation and vertical gardens to create a sustainable habitat tailored for arid desert conditions, serving as a refuge for both people and local ecology.
5 key facts about this project
01
Translucent ETFE structure allows for optimal daylight while minimizing heat gain.
02
Vertical gardens capitalize on sustainable agricultural practices within the habitat.
03
The design incorporates traditional Qanat-inspired water management systems.
04
Natural ventilation is achieved through strategically placed windcatchers.
05
Reinforced concrete and fiberglass materials enhance structural durability and efficiency.
Arcadia is an architectural design project meticulously developed to address sustainability and inhabitability within desert climates. This project integrates historical architectural practices with contemporary design principles to create a self-sustaining habitat that performs effectively in extreme conditions. The central concept of the project is inspired by ancient water management systems, particularly the Qanat, which allows for water transport and management in arid environments. Arcadia aims to establish an ecological equilibrium where human habitation is harmonized with the natural environment.

The design consists of a large semi-transparent dome structure that provides thermal comfort while allowing natural light penetration. This element serves as the primary shelter and is crafted from materials such as ETFE and glass, which enhance energy efficiency while maintaining structural integrity. Internal spaces are organized into multifunctional areas, including vertical gardens that facilitate food production and improve air quality. The circulation pathways integrate seamlessly with these spaces, ensuring fluid movement throughout the habitat.

Unique Design Approaches

One defining feature of Arcadia is its innovative approach to passive environmental control. The incorporation of windcatchers allows for natural ventilation, minimizing the reliance on mechanical systems. This architectural feature is essential in desert climates, where the outdoor temperatures can be extreme. Furthermore, the design employs thermal mass principles, enabling the building to retain and release heat as needed, thus moderating indoor temperatures effectively.

Water management is another critical aspect of the project. Inspired by the Qanat system, the design incorporates a network of underground tunnels facilitating efficient water transport. This not only addresses the scarcity of resources in desert conditions but also reinforces the building's sustainability credentials. The inclusion of vertical gardens supports biodiversity and aids in microclimate control within and around the structure.

Architectural Details and Materials

The choice of materials plays a significant role in the performance of Arcadia. Reinforced concrete is used for its strength and durability, while sustainable timber elements contribute to the aesthetic warmth of the interior spaces. Additionally, the use of fiberglass in combination with glass creates lightweight yet robust structural elements, further enhancing the overall efficiency of the design.

The project's layout and features also respond to climatic variations, ensuring that occupants remain comfortable irrespective of external environmental conditions. The blend of innovative engineering techniques with traditional knowledge provides a substantial framework for future developments in similar contexts.

For those interested in delving deeper into the intricacies of Arcadia, a review of architectural plans, architectural sections, and architectural designs will provide comprehensive insights into its construction and function. Exploring these elements will enhance understanding of the various architectural ideas that are woven throughout the 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.
