Alter is a minimalistic design that focuses on flexibility and user experience. Located in a natural environment, the structure functions as a versatile shelter that can adapt to create various temporary spaces. The main concept centers on encouraging users to personalize their surroundings, fostering a deep connection between the space and its occupants.

Design Concept

The structure features a series of lifted platforms connected to a central pavilion with a corrugated roof. While the main part remains fixed, the walls can slide, and the roof pivots, allowing users to shape their environment according to their needs. This approach creates an interactive space that promotes both community and solitude.

Spatial Organization

The layout consists of three distinct areas: the Attic, Living, and Cellar. Each space is designed to offer unique experiences that serve different functions. The Attic uses a manual pulley system to open the roof, letting in natural light and inviting moments of reflection. This upper space encourages users to engage their imaginations and embrace the concept of daydreaming, emphasized by its capacity for change.

The Living area is designed with varied platforms that allow for personalization. Users can shift timber panels to create their own spaces. This focus on customization promotes active engagement with the architecture, encouraging mindfulness and a sense of belonging.

The Cellar provides a quieter retreat, characterized by its enclosed atmosphere. Here, the design conveys a sense of depth, offering a space for individuals to process thoughts and seek solitude. When all movable components are closed, this area becomes a peaceful sanctuary away from external distractions.

Material Selection

Inspiration for the design comes from traditional New Zealand Department of Conservation (DOC) Huts, incorporating local architectural features. The use of timber, plywood panels, and native hardwood supports efficient construction in remote locations while respecting local building traditions. The red corrugated roof is a distinctive element, acting as a visual focal point in the surrounding landscape.

The ability to manipulate the walls to reveal underlying structural elements adds depth to the user experience. This interaction fosters a sense of independence and promotes a relationship between the natural environment and the architectural space as occupants fully embrace the potential of the design.

The contrast between open and enclosed areas within Alter enhances its adaptability, ensuring that the architecture responds to the needs of individuals and the surrounding landscape.

`
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.
