## Overview

Located in the arid coastal regions of the Gulf Cooperation Council (GCC) countries, the Desert Dwelling is an architectural design focused on sustainability and adaptability. Addressing the environmental challenges characteristic of the region, the design combines local architectural traditions with contemporary practices, aiming to minimize ecological impact while enhancing the user experience.

## Sustainability and Water Management

The design employs several innovative strategies to promote sustainability. Surfaces are treated with hydrophilic coatings to capture atmospheric moisture, converting it into potable water, thus reducing reliance on conventional water sources. Additionally, a rainwater harvesting system is integrated to ensure efficient water management. The dwelling is engineered to operate off-the-grid, utilizing solar energy as its primary power source and prioritizing natural resources for operational efficiency. Natural ventilation is enhanced through a central wind catcher, which facilitates airflow and significantly lessens the need for air conditioning.

## Materiality and User Experience

In selecting materials, the design emphasizes both functionality and aesthetic alignment with the natural surroundings. The south wall incorporates insulated rammed earth, which provides thermal mass to regulate indoor temperatures effectively. Polished concrete flooring offers a cool surface during high temperatures, while large, strategically shaded north-facing windows maximize natural light, enhancing occupant comfort.

The flexibility of the interior space is evident in the open plan layout, featuring a retractable double bed and multi-functional furniture that adapts to varying activities. The color palette reflects natural desert tones, fostering a serene ambiance that complements the dwelling’s environment. Additionally, adjustable mesh shades ensure privacy and light control while integrating technology for improved user comfort. The exterior's simple silhouette and strategic landscaping enhance its visual connection to the surrounding landscape, establishing a seamless integration of built and natural environments.

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.
