Rammed concrete walls and locally sourced clay create a harmonious living environment on a hillside, designed to foster community interaction while addressing accessibility needs.
5 key facts about this project
01
Rammed concrete walls provide significant thermal mass, enhancing energy efficiency.
02
Locally sourced clay is used for earthen coatings, connecting the building to its environment.
03
The design includes universal accessibility features in all residential units.
04
Circular pathways facilitate natural movement and engagement among residents.
05
A bent A-frame structure integrates seamlessly with the hillside topography.

### Overview

The Weik Hill project is situated on a hillside, drawing inspiration from historical hillside villages in Portugal to create a residential community that promotes inclusivity and accessibility. The design employs the natural topography, featuring a gentle slope that encourages social interaction among residents and enhances overall community cohesion. The concept of "Weik," rooted in Old Middle English as a term for a social unit, underscores the project's commitment to fostering a cohesive living environment.

### Spatial Configuration and Accessibility

The architectural layout consists of a variety of living accommodations, including 22 single-bed suites and 21 double-bed suites, complemented by communal dining areas and recreational facilities. Accessibility is a key focus, with universally designed suites equipped for wheelchair use, ensuring that all inhabitants can navigate the space comfortably. Circulation pathways are integrated throughout the design, facilitating movement while encouraging interactions among residents. The inclusion of common gathering spaces and a chapel, with seating for 20, further enhances community engagement.

### Material Selection and Environmental Considerations

The project incorporates a diverse range of materials to reflect a commitment to sustainability and local sourcing. Rammed concrete is utilized for its structural integrity and thermal mass, while local clay provides earthen coatings that add natural textures to the building's form. The design features hardwood flooring for warmth and aesthetic appeal, complemented by expansive floor-to-ceiling glass windows that promote daylighting and connectivity with the outdoors. Steel is used in critical structural elements, ensuring durability, and natural insulation within the walls enhances energy efficiency. These material choices collectively contribute to minimizing the ecological footprint of the development.

`
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.
