Rammed Earth Walls and Shell Flooring in a Cultural Care Centre

Project in-detail

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.

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.
