The Wavehouse is designed to promote a sense of calm and connection with the surrounding landscape. Situated in a lush environment, it serves as a retreat for meditation and self-reflection. The concept emphasizes the relationship between organic forms and nature, creating spaces that engage the senses and support individual well-being.

Design Approach

The approach to design focuses on creating an inviting atmosphere conducive to meditation. The building features a unique egg-cave-like structure that is both appealing and practical. As visitors approach the Wavehouse, they traverse a narrow path that draws their attention to the richness of the natural surroundings. This gradual transition encourages users to leave behind the busyness of daily life and prepare for a peaceful experience.

Structural Components

Geometric principles play a key role in the integrity and flow of the space. The exterior of the Wavehouse follows a Gaussian curve, while the interior employs a catenary arch. These forms provide strength while minimizing the amount of material needed. The layout allows for open areas that enhance movement and interaction, making it easy to navigate the space while appreciating its calming atmosphere.

Material Selection

One significant material used in the construction is rammed earth, known as Taipa. This choice reflects an understanding of how materials can impact comfort and sustainability. Taipa provides good thermal insulation, helping to keep the interior temperature stable. It also allows moisture to escape, which contributes to a healthy indoor climate. Using a natural material helps the building harmonize with its environment, emphasizing a connection to the earth.

Functional Organization

Every aspect of the building is arranged with care. The kitchen, shower, and toilet facilities are integrated into the hillside, reinforcing the bond between the structure and its natural setting. Storage solutions are designed to be discreet, with drawers built into the stairs, allowing for easy access to yoga mats and other items. This thoughtful organization supports practicality while enhancing the user experience.

The large deck extending from the zen-room offers a clear view of the landscape, featuring a water reservoir that serves both functional and aesthetic purposes. The water naturally filters, inviting visitors to engage with this calming element. This interaction with water enriches the overall experience of the Wavehouse, grounding it within the serene setting.

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.
