Elevated above the ground, this housing utilizes earth and wooden frames, integrating a rainwater collection system while preserving green spaces, to provide affordable living options in an urban environment.
5 key facts about this project
01
Elevated housing units allow for natural airflow and light access beneath.
02
Earth used as a primary building material enhances sustainability.
03
Integrated rainwater collection system reduces water dependency.
04
Wooden frames offer flexibility in design and aesthetics.
05
Strategic site selection promotes green space within urban density.

The proposed design addresses the pressing need for affordable housing in London, a city known for its dense urban landscape. The approach focuses on using prefabricated elements, with earth as the primary material enclosed within wooden frames. This choice not only aims to reduce construction costs but also aligns with sustainable practices. The housing integrates living spaces within green areas, creating a functional and aesthetically pleasing environment.

Design Concept

The design emphasizes the coexistence of residential units and green spaces. By elevating the homes several meters off the ground, the project preserves existing parkland and promotes a balance with nature. This elevation allows light and air to flow freely around and beneath the units, enhancing the quality of life for residents while minimizing the impact on the surrounding environment.

Materials and Structure

Wooden facades and brick are employed to provide flexibility in design, catering to various economic needs and personal preferences. The use of these materials ensures a robust structure while allowing for different aesthetic expressions. The arrangement of the housing units is centered around vertical axis columns, which not only reinforces the overall framework but also optimizes the spatial layout.

Water Management System

An important feature is the rainwater collection system made of vertical blinds that capture rainwater and direct it into small storage tanks. This system offers a practical solution for domestic water use, particularly where clean water is not necessary. By promoting water conservation, the design reflects a commitment to resource efficiency and sustainability.

Urban Integration

The project’s site selection strategically utilizes underused urban areas, such as the spaces between roads and adjacent parks. This choice enhances urban density without compromising green areas. Additionally, a phased development approach allows for adjustment based on community needs, ensuring that the housing remains relevant to the population it serves.

The arrangement of the living units offers a variety of layouts, making them suitable for different lifestyles. This flexibility enhances the user experience and fosters a sense of community within the residential environment. Each detail contributes to a vibrant and supportive living space.

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.
