A solar greenhouse integrates with a cross-laminated timber house, providing flexible living spaces and an art workshop that seamlessly connects to the serene lakeside environment.
5 key facts about this project
01
A solar greenhouse acts as a communal space and captures winter sunlight.
02
Cross-laminated timber panels provide structural integrity and promote sustainability.
03
Glazed walls enhance natural light and connect interiors visually with the lake.
04
Flexible workspaces in the art workshop allow for both collaboration and privacy.
05
Protected basements accommodate local bat habitats, supporting biodiversity.

The redevelopment of a lakeside site focuses on creating a painters' house and workshop that harmonize with the natural surroundings while addressing user needs. This project retains the existing structures’ footprints, which will be demolished and replaced by new buildings. The design concept emphasizes lake views and integrates functional spaces to enhance the overall experience.

Design Concept

The design prioritizes several essential elements: respect for the natural environment, an emphasis on views of the lake, the use of renewable energy, and the provision of flexible living and working arrangements. A walkway connects the new structures, providing easy access to the lake while considering local wildlife, such as having protected areas in the basements for bat populations. This pathway not only links the project site to the main road but also ensures year-round accessibility.

Spatial Organization

The layout of the painters' house consists of two apartments, each with two bedrooms located on the ground floor. The upper level is dedicated to living and kitchen spaces, designed to maximize the experience of lake views. A communal area sits between the two residences, surrounded by large glazed walls that allow sunlight to enter, turning it into a usable solar greenhouse during the winter months.

Workshop Integration

The design of the painters' workshop centers on flexibility, accommodating the diverse needs of the artists. Adaptable spaces within the workshop can be configured for communal events or separated into smaller rooms for individual projects through movable curtains. This versatility allows for both social interaction among artists and spaces for focused work.

Materiality and Sustainability

Drawing elements from Latvian vernacular architecture, the design features ground floor cladding that resembles traditional stone basements, while the upper portions incorporate modern wooden cladding. The main structure utilizes laminated wood and cross-laminated timber walls. The roof is made of sheet metal, contributing to the durability of the buildings. Renewable energy systems, including wind turbines, are included, emphasizing a commitment to sustainability and enhancing the connection to the surrounding environment.

Large glazed walls in the communal area serve practical purposes while providing abundant natural light. This design decision enhances the indoor experience, allowing occupants to engage with the seasonal changes outside and the calming presence of the lake.

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.
