Integrating wool insulation with customizable movable steel boxes, this compact home prioritizes sustainability and personal expression while offering flexible living solutions.
5 key facts about this project
01
Wool insulation enhances thermal efficiency.
02
Movable steel boxes allow for space customization.
03
Upcycled wood cases minimize environmental impact.
04
Vertical greenhouse supports sustainable living.
05
Design incorporates off-grid rainwater collection systems.

The design integrates the classic tiny house concept with an emphasis on sustainability and flexibility. Set in a context that encourages innovative living, it prioritizes customizable spaces tailored to residents' needs. The aim is to create environments that adapt and evolve, offering both functionality and a connection to the outside.

Structural Foundation
A strong structural wall forms the backbone of the design, equipped with wool insulation for thermal regulation. This wall supports a range of movable components, including steel boxes and wooden cases, allowing residents to define their space. The emphasis on adaptability provides an opportunity for occupants to personalize their living environment, responding to different life situations and activities.

Spatial Arrangement
The layout includes key areas such as a bedroom designed to provide a natural atmosphere and a living room measuring 25 square meters. The design fosters a fluid relationship between inside and outside spaces, facilitated by sliding boxes that can be moved as needed. This element invites natural light and air, enhancing the overall living experience while reinforcing the bond with the surrounding environment.

Sustainable Practices
Sustainability is a core component of the design, evident through its off-grid systems. Features include an accessible septic tank and ample outdoor storage, which promote efficient space use. A vertical greenhouse serves as both a functional and aesthetic element, while the use of upcycled wood for outdoor cases highlights the commitment to environmental responsibility. The design encourages minimal waste through practical storage solutions, such as compost access and a dedicated kitchen area.

Innovative Elements
Technical innovations such as rainwater collection systems and solar panels demonstrate a focus on reducing dependence on external resources. Each aspect of the design prioritizes practicality and a thoughtful consideration of modern living. The moveable sliding boxes not only serve a functional purpose but also add a dynamic visual appeal to the facade. This feature reinforces the structure's ability to adapt while contributing to its overall character.

`
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.
