With a unique double-skin cooling system inspired by Bedouin architecture, these sustainable lodges enable comfortable living in Abu Dhabi's arid climate while fostering community interaction.
5 key facts about this project
01
Unique double-skin façade enhances natural ventilation and cooling efficiency.
02
Fabrication allows for easy assembly and disassembly to adapt to site conditions.
03
Wooden framework combined with soundproofing materials ensures acoustic comfort.
04
Efficient water management system supports two days of supply for occupants.
05
Solar panels generate renewable energy to power cooling and lighting systems.

The Megadunes Ecolodges are located in Abu Dhabi, a region known for its dry climate and rich Bedouin culture. These lodges serve as sustainable living spaces that reflect both traditional architecture and modern engineering techniques. The design focuses on effective heat management while promoting a relationship between the structures and the surrounding landscape.

Architecture Concept
The design emphasizes a hybrid climatic system, inspired by the ventilation features of traditional Bedouin tents. Each lodge has a double skin that promotes airflow as hot air rises and escapes. This approach enhances energy efficiency and creates a comfortable indoor climate, responding well to the high temperatures typical of the area.

Spatial Arrangement
The lodges are designed in circular forms, with interiors that evoke natural canyon shapes. This layout allows for easy movement between spaces and encourages social interaction among residents. The design emphasizes a connection to nature, creating an intimate experience with the surrounding environment.

Structural Design
A wooden framework supports the lodges, complemented by drywall interiors. This combination ensures both strength and lightweight adaptability to the varied soil conditions of the site. Soundproofing materials are used in the walls to enhance privacy and comfort. Additionally, the lodges are raised on micro piles, ensuring stability across different ground types.

Sustainable Systems
Efficient energy use is a key feature of the design. The lodges utilize high-efficiency fan coil units for cooling, along with low-energy heat pumps that operate on solar power. This reliance on renewable energy significantly reduces the need for conventional power sources. The water system is well-planned, with supply levels calibrated for two days of use, including water-saving fixtures and a management system for wastewater.

The integration of solar energy includes a lithium battery, making energy available when needed, especially at night. Overall, the design prioritizes sustainability while ensuring comfort. The thoughtful combination of natural systems and modern technology creates an environment that is both functional and respectful of the local climate and culture.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
