Rammed Earth Structure Nurtures Biodiversity Through Organic Growth

Project in-detail

Constructed from rammed earth and designed with a material gradient, the incubator supports local flora through a dynamic microclimate while focusing on ecological rehabilitation in the desertifying environment of Delos Island.
5 key facts about this project
01
Constructed with a variable material gradient to support structural stability and nutrient release.
02
Functions through three distinct stages to facilitate ecological rehabilitation over time.
03
Serves as both an incubator for local flora and a shelter for wildlife.
04
Utilizes rammed earth for high thermal mass and biodegradability.
05
Strategically placed openings allow sunlight to create dynamic light patterns within the structure.

The Hearth incubator is a well-considered structure located on Delos Island in the Cyclades archipelago of southern Greece. It aims to rehabilitate landscapes that are suffering from rapid desertification. The design serves as a temporary, biodegradable solution for supporting local flora while also accommodating various forms of wildlife. The concept is grounded in creating microclimates that enhance the conditions needed for plant growth and contribute positively to the surrounding ecosystem.

Design Concept

The design revolves around fostering ecological growth through a structured process. The Hearth operates in three stages that allow it to adapt and change over time. Initially, it cools the ground, increases moisture levels, and provides shaded areas for local fauna. This first phase not only aids in environmental recovery but also promotes awareness among visitors, blending educational elements with practical function.

Stages of Development

As the project progresses, the Hearth gradually releases a combination of local shrub and grass seeds, influenced by seasonal rains. This stage highlights the connection between the structure and natural processes, making it an active participant in its environment. The architectural form becomes a facilitator of ecological transformation, adapting to various environmental conditions.

Self-Sustaining Habitat

In its final stage, the Hearth evolves into a self-sustaining green incubator. As it dissolves into the landscape, it leaves behind nutrient-rich topsoil that promotes the growth of diverse plant life. This transformation illustrates the long-term effects of the structure on the ecosystem, contributing to a healthier and more balanced environment.

Materials and Sustainability

The construction employs rammed earth as its primary material, a choice that reinforces sustainable building practices. This material offers high thermal mass and a substantial surface area, making it effective as a heat sink while allowing for gradual biodegradability. The pillars are designed with a varied material gradient, leading to stable structure and controlled release of nutrients and seeds. This thoughtful engineering demonstrates a strong understanding of the relationship between architecture and nature.

The Hearth incubator exemplifies the potential for design to engage with and foster the environment. Sunlight filters through strategically placed openings, creating soft patterns of light on the ground. These details enhance the ecological experience of the setting, reminding visitors of the connection between human-made structures and the natural world.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
