Mycelium-Insulated Living Space With Hydroponic Terrace

Project in-detail

Constructed with raw earth and mycelium insulation, the design incorporates a hydroponic terrace, creating a sustainable living space that seamlessly blends modern functionality with ecological principles.
5 key facts about this project
01
Constructed using 3D-printed raw earth for structural integrity.
02
Features a bio-plastic grid made from algae to enhance ecological balance.
03
Incorporates an efficient rainwater collection system for sustainable water use.
04
Equipped with a hydroponic system for cultivating plants in an urban setting.
05
Utilizes a mycelium insulation layer for improved thermal and acoustic performance.

The Symbiotic Dome serves as an exploration of adaptability and sustainability within a compact living space. Its design prioritizes ecological balance while also considering the needs of its occupants. The overall approach focuses on creating versatile environments where spaces can easily change based on different activities and daily routines. The concept emphasizes the importance of open areas combined with efficient use of materials to foster a harmonious relationship between people and their living surroundings.

Design Concept

The layout features movable walls that allow for a variety of configurations. Occupants can create distinct rooms for privacy or open up the space for communal gatherings. This flexibility supports various activities, enhancing how users interact with their environment. The design invites a rethinking of traditional living spaces by offering dynamic options that adjust to individual preferences and needs.

Terrace Integration

An outdoor terrace forms an essential part of the design, set apart from the surrounding environment by a grid made from algae-based bio-plastic. This feature adds visual interest while also functioning as a hydroponic garden for small plants. By integrating nature into the living space, the design showcases the potential benefits of greenery, promoting health and well-being among occupants.

Materiality and Construction

The materials chosen reflect a dedication to sustainability and efficiency. The walls are created using a 3D printing process that employs raw earth, providing strength while minimizing environmental impact. Mycelium is incorporated for insulation, both thermal and acoustic. Furthermore, a rainwater collection system installed on the roof supports responsible water management, while algae-filled photobioreactor cells provide an innovative energy solution, functioning similarly to conventional solar panels.

Functional Systems

A significant aspect of the design involves the algae photobioreactor system, which includes a growth tank for harvesting algae and a compressed air inoculation system. This setup efficiently recycles water, utilizing grey water to minimize waste generation. The fast growth rate of the algae enhances energy production, allowing the structure to maintain its operations sustainably. Finally, the building method involves 3D printing technology, which reduces typical construction waste.

The dome's outer layer made from algae bioplastic adapts to various environmental conditions, ensuring the structure remains protected while supporting ecological practices.

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.
