The Meditation Cabin: Lighthouse is situated in Itabashi City, Tokyo, and provides a space for meditation and relaxation amidst busy urban life. Designed as a retreat for individuals, the tower cabin stands with a footprint of less than 6 square meters. Its compact size allows for flexible placement in various locations, making it an accessible sanctuary for those seeking a moment of peace.

Architectural Concept

The cabin features a hyperboloid form, which enhances its structural stability and efficiency. The superstructure is made of prefabricated elements, allowing for quick assembly in a factory setting and easy relocation to different sites. This modular design caters to the varying needs of urban users while ensuring the cabin is efficient to build and install.

Functional Organization

Inside, the cabin includes three distinct levels to serve specific purposes. The ground level acts as a transition space, allowing visitors to leave behind the stresses of the outside world. Enclosed by a metal mesh, this area offers both visual privacy and abundant light, creating an inviting atmosphere that connects visitors with their surroundings.

The second level is focused on rest and recovery. It is designed with comfortable seating spaces, encouraging visitors to take a break and enjoy the tranquility. This thoughtful arrangement fosters a sense of comfort, making it easy to unwind.

On the rooftop, a meditative space awaits, complete with panoramic views of the city. Here, ivy is planted on the balcony, adding greenery and promoting a bond with nature. This element enriches the experience, inviting reflection and a deeper connection to the environment.

Materiality

Sustainability is a key consideration in the design. Bamboo is used throughout the cabin, valued for its strength and environmental benefits. Its lightweight characteristics simplify construction and transport, making it a practical choice for a modular building. The metal mesh on the ground level contributes to privacy, while also keeping the space airy and bright.

The rooftop area, adorned with lush ivy, allows visitors to pause and reflect while surrounded by nature. This combination creates an environment that encourages mindfulness and helps individuals reconnect with themselves amid the urban setting.

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.
