The CTRL+P Home is an innovative housing solution designed to meet the demands of modern living. Positioned in both urban and rural settings, it provides a compact and practical space for individuals and families. The design emphasizes versatility and sustainability, aiming to create a comfortable environment that encourages a connection with nature and responsible living.

Spatial Efficiency and Flexibility

The layout of the CTRL+P Home focuses on making the most of limited space. It includes interconnected areas that allow for various activities, such as working, cooking, and relaxing, all within close proximity. This design maximizes functionality, providing room for personal privacy while still encouraging social interaction among residents. The result is a living space that adapts as needs change over time.

Sustainable Energy and Water Management

A significant aspect of the CTRL+P Home is its capability for off-grid living. The home incorporates systems for collecting solar energy and harvesting rainwater, allowing it to operate independently from traditional utilities. This approach reduces reliance on external resources, promoting a self-sufficient lifestyle. Additionally, the design includes areas for growing food, which further supports sustainability and food security.

Material Innovation and Construction Techniques

The CTRL+P Home employs modern construction methods, particularly 3D printing, to create its structure. This technique supports rapid building while using fewer resources. The home also makes use of biobased materials, like hemp composites, which are environmentally friendly and contribute to a healthier space. These materials are a key part of the strategy to lessen the overall impact on the environment during construction and throughout the home's lifetime.

Design Integration with Nature

Biophilic design elements are prevalent in the CTRL+P Home, promoting a close relationship between the inhabitants and their surroundings. Large windows and easy outdoor access ensure that natural light fills the interior spaces. This connection to the outdoors encourages a sense of well-being and provides scenic views that enhance day-to-day living.

One notable aspect of the CTRL+P Home is its focus on creating opportunities for gardening and cultivation, thereby supporting a lifestyle that values both nature and self-sufficiency. The design creates an environment where residents can engage with their surroundings actively.

`
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.
