## Overview
Located in Dubai, the semi-subterranean house embodies a contemporary response to the region's harsh climatic conditions while prioritizing cultural heritage and environmental sustainability. The design integrates innovative architectural strategies rooted in local traditions, effectively addressing the significant challenges posed by the desert environment. Emphasizing energy efficiency, thermal comfort, and biophilic principles, the project serves as a blueprint for sustainable living in urban contexts.

### Site Configuration and Spatial Organization
The layout of the house is meticulously planned to optimize natural ventilation and minimize solar exposure. The ground floor accommodates communal gathering spaces, such as the Majlis, living room, kitchen, and bathrooms, which are designed to enhance light flow and encourage airflow. Private spaces, including bedrooms and utility areas, are situated underground to promote relaxation and privacy. The first floor features a balcony and additional bedrooms, ensuring expansive views while maintaining sheltered privacy. This configuration allows for passive cooling and thermal comfort, crucial in the Dubai climate.

### Material Selection and Sustainability
The project incorporates a range of carefully selected materials that contribute to its sustainability goals. Insulated Concrete Forms (ICF) provide enhanced thermal insulation, while terracotta elements are used for perforated screens that offer both shade and aesthetic value. Natural plasters resonate with the local architectural style and support environmental adaptability. Incorporating local plant species in landscaping fosters a biophilic connection to the environment. The integration of solar panels further underscores the commitment to sustainable energy solutions, reducing reliance on fossil fuels and supporting the overall efficiency of the residence.

The exterior features terracotta screens designed with parametric patterns that reflect cultural motifs, merging functionality with aesthetic appeal. The semi-subterranean approach serves to significantly reduce energy costs associated with cooling, demonstrating a forward-thinking framework that balances modern needs with traditional influences.

`
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.
