Rammed earth walls and flooring made from local shells create a culturally resonant care centre that serves the healthcare needs of the Quandamooka people.
5 key facts about this project
01
Rammed earth walls utilize local soil, connecting the building to its landscape.
02
Shell flooring incorporates collected materials from the nearby shoreline.
03
A central campfire hearth serves as a multifunctional gathering space.
04
Design integrates natural plant fibers for woven screens, enhancing user privacy.
05
The layout promotes intuitive navigation and strong community interaction.

The Minjerribah Care Centre is located on North Stradbroke Island in Queensland, designed to serve the healthcare needs of the Quandamooka people. The facility focuses on creating a supportive environment that respects and integrates the cultural identity of the local Indigenous community. The overall design emphasizes accessibility and community engagement, aiming to enhance both emotional and physical wellbeing.

Design Concept

The layout of the care centre is organized to encourage easy navigation and foster social interaction. Key spaces, including the main entrance, reception area, and communal facilities such as the chapel and reading room, are thoughtfully placed to support their respective functions. This arrangement allows users to move through the space intuitively while promoting a sense of community.

Visual Integration

A significant feature of the design is its strong connection to the natural landscape. Large windows and outdoor spaces provide clear views of the beach and surrounding environment. This connection allows people to engage with nature, which contributes to an overall healing experience. The design facilitates a strong relationship between indoor living and the outdoor environment.

Material Use

In line with the concept of "Care for the Country," materials chosen for construction are essential to the design. Rammed earth walls use local soil, which strengthens the link to the landscape. Concrete from a nearby quarry supports the structure, while screens made from natural plant fibers offer privacy without sacrificing light. Recycled timber frames are used throughout the building to minimize environmental impact and promote sustainability.

Key Design Features

The campfire or hearth serves as a central gathering space, encouraging community interaction. It acts as a focal point for both social activities and cultural practices. The thoughtful arrangement of functional spaces, such as quiet rooms and other amenities, meets the specific needs of the community while honoring cultural traditions.

In the interior, the use of shells collected from the shoreline in the flooring adds a unique tactile quality. This detail enhances the sensory experience of the space and reinforces the connection to the coastal landscape, allowing users to feel a part of their environment.

`
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.
