5 key facts about this project
01
Constructed with cross-laminated timber for enhanced structural integrity and insulation.
02
Incorporates a rainwater harvesting system for self-sufficient water usage.
03
Features charred wooden shingles for durability and weather resistance.
04
Designed with a bent A-frame structure for dynamic spatial experience.
05

### Overview

The sustainable cabin is located in Latvia, designed to meet the demands of varying seasonal climates while integrating with the natural environment. The project emphasizes low maintenance and functionality through the application of sustainable practices and material usage.

### Spatial Strategy

The cabin features a layout that distinguishes between public and private areas, enhancing user experience and comfort. A covered porch facilitates interaction and provides shelter from the elements, while an entrance area minimizes environmental infiltration, enhancing hygiene and accessibility through the integration of a composting toilet. Flexible sleeping arrangements, such as foldable platforms, contribute to efficient space utilization, enhancing privacy without compromising functionality.

### Material Selection and Sustainability

The use of materials is a defining characteristic of the cabin’s design. Cross-laminated timber (CLT) serves as the primary structural element, offering lightness and thermal efficiency while ensuring integration with the forested landscape. Siberian larch cladding complements the natural surroundings with its weather-resistant properties, while a concrete base provides stability in the coastal environment. Triple glazing enhances insulation and allows for ample natural light, supporting energy efficiency.

Sustainable practices are integral to the project, featuring a rainwater harvesting system that promotes self-sufficiency and minimizes dependence on external water sources. The possible inclusion of solar panels contributes to energy efficiency, while the selected materials are durable and low-maintenance, addressing the climatic challenges of the area while ensuring the longevity of the structure. The cabin's adaptable orientation accommodates varying site conditions, thereby allowing for privacy while fostering community engagement through its thoughtful layout design.

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.
