A cylindrical light well and built-in clay chimney define a microhouse that seamlessly integrates nature with functional living spaces, promoting sustainable off-grid living in a compact form.
5 key facts about this project
01
Cylindrical light well enhances natural light and spatial perception.
02
Built-in clay chimney efficiently supports heating requirements.
03
Modular "moveonetes" allow flexible organization of living spaces.
04
Circular openings frame views and connect indoor and outdoor environments.
05
Sustainable materials are sourced locally to minimize environmental impact.

The "Pinecone" microhouse offers a modern solution to living in harmony with nature, balancing function and simplicity. Located in a boreal mountain area, the design seeks to create an environment where residents can reconnect with the natural world while enjoying essential comforts. The structure draws inspiration from local plants, particularly the shapes of pine trees and pinecones.

Design Concept
The core concept features a cylindrical light well at the center of the house. This design allows for abundant natural light, contributing to an open feeling within the compact space. Surrounding the light well are various areas designed for specific purposes, such as cooking, bathing, and relaxing. This layout helps maximize usability and encourages flexibility for different activities.

Spatial Organization
The microhouse prioritizes a minimalist approach, minimizing excess furniture to enhance the connection between indoor and outdoor spaces. Large circular openings, inspired by tree hollows, frame views of the landscape and encourage interaction with the environment. These design choices promote a daily engagement with nature, enriching the living experience.

Material Use
The choice of materials reflects a commitment to sustainability and energy efficiency. A built-in clay chimney provides effective heating, contributing to overall comfort. Insulation techniques use local resources that help lower energy needs while maintaining a cozy atmosphere.

The design of the "Pinecone" microhouse is defined by the thoughtful circular openings that connect the interior spaces with the natural surroundings. These elements invite light and views into the home, creating a sense of warmth and clarity that enhances daily living.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
