Constructed with cross-laminated timber and mineral wool insulation, this modular housing solution challenges traditional living by maximizing utility within a compact footprint while providing flexible space for modern urban living.
5 key facts about this project
01
Modular design reuses the dimensions of a parking space for housing solutions.
02
Features a retractable bed for versatile use of space in the dual-purpose room.
03
Roof integration of solar panels promotes energy efficiency and sustainability.
04
Constructed with structural mineral wool insulated CLT for better thermal performance.
05
Outdoor terrace provides access to light and air in a compact urban setting.

The Purposeful Spaces project offers a practical solution to the housing needs of young people living in urban areas. As cities grow and living costs increase, finding adequate and affordable housing becomes a challenge. The design concept focuses on reimagining living spaces by adapting dimensions commonly found in parking lots. This innovative approach leads to the creation of modular housing units that can be produced efficiently, providing both functionality and flexibility for residents.

Concept and Organization

The layout consists of two levels, organized to enhance daily living. The ground floor includes essential areas such as a kitchen, living room, and bathroom, designed with clear separations that improve accessibility. On the first floor, residents will find a workspace and a bedroom, along with a versatile room that can be used as either an office or guest bedroom, thanks to a retractable bed that saves space.

Utilization of Outdoor Spaces

Outdoor areas play an important role in the design. The roof features a terrace that allows for natural light and fresh air, which is especially valuable in crowded urban settings. Another section of the roof is reserved for solar panels, capturing renewable energy that can be stored for use in the home. This element of the design supports sustainability while making efficient use of available resources.

Material Considerations

The exterior walls consist of structural mineral wool insulated cross-laminated timber (CLT). This material not only provides a sturdy framework but also enhances thermal performance. The use of exterior glazing with outward-opening windows allows for better air circulation while maintaining privacy and safety. These material choices reflect a focus on practical living while promoting environmental responsibility.

One notable feature of Purposeful Spaces is its focus on adaptability. Adjustable elements, like a height-adjustable dining table, cater to the various needs of residents. The design prioritizes comfort without compromising on function, allowing for a living environment that can change according to individual lifestyles and preferences.

`
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.
