## 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 Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
