5 key facts about this project
01
Utilizes charred wooden shingles for enhanced durability and fire resistance.
02
Incorporates cross-laminated timber panels to reduce carbon footprint and improve insulation.
03
Features a bent A-frame design that allows optimal natural light penetration.
04
Includes dedicated spaces for culinary education linked to urban agriculture.
05
Facilitates community interaction through multifunctional areas designed for engagement.

## Project Overview
Located in San Francisco, California, the Green-House project occupies one of the few remaining plots of land historically used for farming. The design seeks to acknowledge this agricultural legacy while addressing the modern demand for multifunctional spaces. By combining elements of traditional greenhouses with residential structures, the project aims to create a hybrid facility that serves both ecological and community objectives.

## Spatial Organization and User Experience
The architectural layout includes two primary components: "wooden boxes" that house flexible, multifunctional areas and "glass boxes" dedicated to agricultural uses. This spatial strategy allows the structure to reflect its historical context while accommodating the diverse needs of urban life. The design encourages interaction among community members through various shared spaces, such as a youth center and a market area. These environments foster engagement and promote sustainable practices among residents.

## Material Selection and Sustainability
Materials play a crucial role in the project's environmental strategy. The façade utilizes expansive glass to optimize natural light and solar gain, while wooden elements contribute warmth and emphasize the use of renewable resources. Metal frames provide structural support and durability, enhancing the building's overall resilience. Insulation materials are strategically integrated to improve energy efficiency, contributing to the project's adaptive response to climate variations and reinforcing its commitment to sustainability. The overall design seeks to establish a harmonious connection between the built environment and its natural surroundings, aligning with the vision of creating a community-oriented, environmentally sustainable urban space.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
