Constructed with recycled plastics and concrete, this pyramid-shaped dwelling integrates modular design for adaptive living in a sustainable environment.
5 key facts about this project
01
Constructed entirely from recycled plastics, reducing environmental impact.
02
Pyramid shape optimizes natural ventilation and rainwater management.
03
Modular layout allows for flexible reconfiguration of living spaces.
04
Pre-fabricated components streamline assembly and minimize on-site waste.
05
Integration of communal and private areas fosters a sense of community.

### Overview and Concept

The Stack House is designed as a sustainable residential structure that employs innovative construction methods with a focus on ecological integrity. Located in a landscape that supports natural integration, this project utilizes modular construction techniques that allow for adaptability and efficient material use. The design emphasizes the principles of sustainable living through carefully considered material selection and spatial organization.

### Architectural Configuration and Functionality

The Stack House features a distinctive pyramid shape, which serves significant functional purposes. The sloped roof aids in rainwater management by efficiently directing runoff for potential harvest and promotes natural ventilation, enhancing indoor air quality. The building’s geometry incorporates a facade with a mix of triangular elements and perforated sections, optimizing both aesthetic appeal and functional light control while maintaining privacy.

The interior is organized into flexible modules that cater to diverse living arrangements, allowing occupants to adapt spaces as their needs evolve. Key areas include a central living space designed for interaction, private sleeping and study modules that ensure seclusion, and multi-functional zones that encourage community engagement. Unique design elements, such as suspended netting in high-ceiling spaces, provide innovative lounging areas while optimizing spatial utility through built-in storage solutions.

### Material Selection and Sustainability Practices

The project prioritizes sustainability by utilizing a variety of recycled and locally sourced materials. Key components include:

- **Recycled Plastics**: Shredded plastics are transformed into structural elements, addressing waste reduction and providing a sustainable material narrative.
- **Concrete**: Selected for its structural integrity, this material also contributes to cost efficiency.
- **Plywood and Aluminum**: Plywood enhances warmth in the interior while adding structural support, with aluminum used for durability and low maintenance in window framing.
- **Glass**: Large windows maximize natural light, fostering a connection between interior and exterior environments.

These material choices illustrate a commitment to resourcefulness, as well as the integration of environmental consciousness into the architectural design. Additionally, the use of prefabrication techniques enhances construction efficiency, minimizing waste and ensuring quality control during assembly. The design strategically incorporates energy-efficient elements, such as optimized window placement to maximize natural light and breezes, aligning with passive solar heating principles.

Vancouver Tall Challenge: Building Higher Downtown

`
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.
